Visions of the Future: Life in the 2030’s

future-city-1Gauging what life will be like down the road based on the emerging trends of today is something that scientists and speculative minds have been doing since the beginning of time. But given the rapid pace of change in the last century – and the way that it continues to accelerate – predicting future trends has become something of a virtual necessity today.

And the possibilities that are expected for the next generation are both awe-inspiring and cause for concern. On the one hand, several keen innovations are expected to become the norm in terms of transportation, education, health care and consumer trends. On the other, the growing problems of overpopulation, urbanization and Climate Change are likely to force some serious changes.

index-awards-horizontal-galleryHaving read through quite a bit of material lately that comes from design firms, laboratories, and grant funds that seek to award innovation, I decided to do a post that would take a look at how life is expected to change in the coming decades, based on what we are seeing at work today. So here we go, enjoy the ride, and remember to tip the driver!

Housing:
When it comes to designing the cities of the future – where roughly 5 of the worlds 8.25 billion people are going to live – meeting the basic needs of all these folks is complicated by the need to meet them in a sustainable way. Luckily, people all across the world are coming together to propose solutions to this problem, ranging from the small and crafty to the big and audacious.

wallsmart_paintConsider that buildings of the future could be coated with Smart Paint, a form of pigment that allows people to change the color of their domicile simply by pushing a button. Utilizing nano-particles that rearrange themselves to absorb a different part of the spectrum, the paint is able to reflect whatever wavelength of visible light the user desires, becoming that color and removing the need for new coats of paint.

And consider that apartments and houses in this day could be lighted by units that convert waste light energy from their light bulbs back into functional ambient light. This is the idea behind the Trap Light, a lamp that comes equipped with photoluminescent pigments embedded directly into the glass body. Through this process, 30 minutes of light from an incandescent or LED light bulb provides a few hours of ambient lighting.

trap_lightAnd in this kind of city, the use of space and resources has come to be very efficient, mainly because it has had to. In terms of low-rent housing, designs like the Warsaw-inspired Keret House are very popular, a narrow, 14-sqaure meter home that still manages to fit a bathroom, kitchen and bedroom. Being so narrow, city planners are able to squeeze these into the gaps between older buildings, its walls and floors snapping together like Lego.

When it comes to other, larger domiciles (like houses and apartment blocks), construction is likely to become a much more speedy and efficient process – relying on the tools of Computer-Assisted Design (CAD) and digital fabrication (aka. the D-process). Basically, the entire fabrication process is plotted in advance on computer, and then the pieces are tailor made in the factory and snapped together on site.


And lets not forget anti-gravity 3-D printing as a means of urban assembly, as proposed by architecture students from the Joris Laarman Lab in Amsterdam. Using quick-hardening materials and dispensed by robot-driven printers, entire apartment blocks – from electronic components to entire sections of wall – within a few days time. Speedier, safer and more efficient than traditional construction.

Within these buildings, water is recycled and treated, with grey water used to fertilize crops that are grown in house. Using all available spaces – dedicated green spaces, vertical agriculture, and “victory gardens” on balconies – residents are able to grow their own fruits and vegetables. And household 3-D food printers will dispense tailor-made treats, from protein-rich snacks and carb crackers to chocolate and cakes.

anti-grav3dAnd of course, with advances in smart home technology, you can expect that your appliances, thermostat, and display devices will all be predictive and able to anticipate your needs for the day. What’s more, they will all be networked and connected to you via a smartphone or some other such device, which by 2030, is likely to take the form of a smartwatch, smartring or smartbracelet.

Speaking of which…

Smart Devices and Appliances:
When it comes to living in the coming decades, the devices we use to manage our everyday lives and needs will have evolved somewhat. 3-D printing is likely to be an intrinsic part of this, manufacturing everything from food to consumer products. And when it comes to scanning things for the sake of printing them, generating goods on demand, handheld scanners are likely to become all the rage.

consumer_2030That’s where devices like the Mo.Mo. (pictured above) will come into play. According to Futurist Forum, this molecular scanning device scans objects around your house, tells you what materials they’re made from, and whether they can be re-created with a 3-D printer. Personal, household printers are also likely to be the norm, with subscriptions to open-source software sites leading to on-demand household manufacturing.

And, as already mentioned, everything in the home and workplace is likely to be connected to your person through a smart device or embedded chips. Consistent with the concept of the “Internet of Things”, all devices are likely to be able to communicate with you and let you know where they are in real time. To put that in perspective, imagine SIRI speaking to you in the form of your car keys, telling you they are under the couch.

future-officeTelepresence, teleconferencing and touchscreens made out of every surface are also likely to have a profound effect. When a person wakes in the morning, the mirror on the wall will have displays telling them the date, time, temperature, and any messages and emails they received during the night. When they are in the shower, the wall could comforting images while music plays. This video from Corning Glass illustrates quite well:


And the current range of tablets, phablets and smartphones are likely to be giving way to flexible, transparent, and ultralight/ultrathin handhelds and wearables that use projection and holographic technology. These will allow a person to type, watch video, or just interface with cyberspace using augmented reality instead of physical objects (like a mouse or keyboard).

And devices which can convert, changing from a smartphone to a tablet to a smartwatch (and maybe even glasses) are another predicted convenience. Relying on nanofabrication technology, Active-Matrix Organic Light-Emitting Diode (AMOLED) technology, and touch-sensitive surfaces, these devices are sure to corner the market of electronics. A good example is Nokia’s Morph concept, shown here:


Energy Needs:
In the cities of the near-future, how we generate electricity for all our household appliances, devices and possibly robots will be a going concern. And in keeping with the goal of sustainability, those needs are likely to be met by solar, wind, piezoelectric, geothermal and tidal power wherever possible. By 2030, buildings are even expected to have arrays built in to them to ensure that they can meet their own energy needs independently.

strawscaperThis could look a lot like the Strawscraper (picture above), where thousands of fronds utilize wind currents to generate electricity all day long; or fields filled with Windstalks – where standing carbon-fiber reinforced poles generate electricity by simply swaying with the wind. Wind farms, or wind tunnels and turbines (as envisioned with the Pertamina Energy Tower in Jakarta) could also be used by buildings to do the same job.

In addition, solar panels mounted on the exterior would convert daylight into energy. Assuming these buildings are situated in low-lying areas, superheated subterranean steam could easily be turned into sources of power through underground pipes connected to turbines. And for buildings located near the sea, turbines placed in the harbor could do the same job by capturing the energy of the tides.

asiancairns_pl14mFurthermore, piezoelectric devices could be used to turn everyday activity into electricity.  Take the Pavegen as an example, a material composed of recycled tires and piezoelectric motors that turns steps into energy. Equipping every hallway, stairwell and touch surface with tensile material and motors, just about everything residents do in a building could become a source of added power.

On top of that, piezoelectric systems could be embedded in roads and on and off ramps, turning automobile traffic into electrical power. In developed countries, this is likely to take the form of advanced materials that create electrical charges when compressed. But for developing nations, a simple system of air cushions and motors could also be effective, as demonstrated by Macías Hernández’ proposed system for Mexico City.

And this would seem like a good segue into the issue of…

Mass Transit:
future-city3According to UN surveys, roughly 60% of the world’s population will live in cities by the year 2030. Hopefully, the 5.1 billion of us negotiating tight urban spaces by then will have figured out a better way to get around. With so many people packed into dense urban environments, it is simply not practical for all these individuals to rely on smog-emitting automobiles.

For the most part, this can be tackled by the use of mass transit that is particularly fast and efficient, which are the very hallmarks of maglev trains. And while most current designs are already speedy and produce a smaller carbon footprint than armies of cars, next-generation designs like the Hyperloop, The Northeast Maglev (TNEM), and the Nagoya-Tokyo connector are even more impressive.

scmaglev-rendering-washington-stationDubbed by Elon Musk as the “fifth form” of transportation, these systems would rely on linear electric motors, solar panels, and air cushions to achieve speeds of up to 1290 kilometers per hour (800 mph). In short, they would be able to transport people from Los Angeles and San Francisco in 30 minutes, from New York to Washington D.C. in 60 minutes, and from Nagoya to Tokyo in just 41.

When it comes to highways, future designs are likely to take into account keeping electric cars charged over long distances. Consider the example that comes to us from Sweden, where Volvo is also working to create an electric highway that has embedded electrical lines that keep cars charged over long distances. And on top of that, highways in the future are likely to be “smart”.

electric-highwayFor example, the Netherlands-based Studio Roosegaarde has created a concept which relies on motion sensors to detect oncoming vehicles and light the way for them, then shuts down to reduce energy consumption. Lane markings will use glow-in-the-dark paint to minimize the need for lighting, and another temperature-sensitive paint will be used to show ice warnings when the surface is unusually cold.

In addition, the road markings are expected to have longer-term applications, such as being integrated into a robot vehicle’s intelligent monitoring systems. As automated systems and internal computers become more common, smart highways and smart cars are likely to become integrated through their shared systems, taking people from A to B with only minimal assistance from the driver.

smart-highwaysAnd then there’s the concept being used for the future of the Pearl River Delta. This 39,380 square-km (15,200 square-mile) area in southeastern China encompasses a network of rapidly booming cities like Shenzhen, which is one of the most densely populated areas in the world. It’s also one of the most polluted, thanks to the urban growth bringing with it tons of commuters, cars, and vehicle exhaust.

That’s why NODE Architecture & Urbanism – a Chinese design firm – has come up with a city plan for 2030 that plans put transportation below ground, freeing up a whole city above for more housing and public space. Yes, in addition to mass transit – like subways – even major highways will be relegated to the earth, with noxious fumes piped and tunneled elsewhere, leaving the cityscape far less polluted and safer to breathe.

Personal cars will not be gone, however. Which brings us to…

Personal Transit:
electric_carIn the future, the majority of transport is likely to still consist of automobiles, albeit ones that overwhelmingly rely on electric, hydrogen, biofuel or hybrid engines to get around. And keeping these vehicles fueled is going to be one of the more interesting aspects of future cities. For instance, electric cars will need to stay charged when in use in the city, and charge stations are not always available.

That’s where companies like HEVO Power come into play, with its concept of parking chargers that can offer top-ups for electric cars. Having teamed up with NYU Polytechnic Institute to study the possibility of charging parked vehicles on the street, they have devised a manhole c0ver-like device that can be installed in a parking space, hooked up to the city grid, and recharge batteries while commuters do their shopping.

chevy_envAnd when looking at individual vehicles, one cannot underestimate the role by played by robot cars. Already, many proposals are being made by companies like Google and Chevrolet for autonomous vehicles that people will be able to summon using their smartphone. In addition, the vehicles will use GPS navigation to automatically make their way to a destination and store locations in its memory for future use.

And then there’s the role that will be played by robotaxis and podcars, a concept which is already being put to work in Masdar Eco City in the United Arab Emirates, San Diego and (coming soon) the UK town of Milton Keynes. In the case of Masdar, the 2GetThere company has built a series of rails that can accommodate 25,000 people a month and are consistent with the city’s plans to create clean, self-sustaining options for transit.

Robotaxi_2getthereIn the case of San Diego, this consists of a network known as the Personal Rapid Transit System – a series of on-call, point to point transit cars which move about on main lines and intermediate stations to find the quickest route to a destination. In Britian, similar plans are being considered for the town of Milton Keynes – a system of 21 on-call podcars similar to what is currently being employed by Heathrow Airport.

But of course, not all future transportation needs will be solved by MagLev trains or armies of podcars. Some existing technologies – such as the bicycle – work pretty well, and just need to be augmented. Lightlane is a perfect example of this, a set of lasers and LED lights that bikers use to project their own personal bike lane from under the seat as they ride.

lightlaneAnd let’s not forget the Copenhagen Wheel, a device invented by MIT SENSEable City Lab back in 2009 to electrify the bicycle. Much like other powered-bicycle devices being unveiled today, this electric wheel has a power assist feature to aid the rider, a regenerative braking system that stores energy, and is controlled by sensors in the peddles and comes with smart features can be controlled via a smartphone app.

On top of all that, some research actually suggests that separating modes of transportation – bike lanes, car lanes, bus lanes, etc. – actually does more harm than good to the people using them. In Europe, the traffic concept known as “shared spaces” actually strips paths of traffic markings and lights, and allow walkers and drivers to negotiate their routes on their own.

transportation_tripanelShared spaces create more consideration and consciousness for other people using them, which is why the Boston architecture firm Höweler + Yoon designed the “Tripanel” as part of their larger vision for the Boston-Washington corridor (aka. “Boswash”). The Tripanel features a surface that switches among grass, asphalt, and photovoltaic cells, offering a route for pedestrians, bikers, and electric cars.

Education:
When it comes to schooling ourselves and our children, the near future is likely to see some serious changes, leading to a virtual reinventing of educational models. For some time now, educators have been predicting how the plurality of perspectives and the rise of a globalized mentality would cause the traditional mode of learning (i.e. centralized schools, transmission learning) to break down.

Classroom-of-the-Future01And according to other speculative thinkers, such as Salim Ismail – the director of Singularity University – education will cease being centralized at all and become an “on-demand service”. In this model, people will simply “pull down a module of learning”, and schooldays and classrooms will be replaced by self-directed lessons and “microlearning moments”.

In this new learning environment, teleconferencing, telepresence, and internet resources are likely to be the main driving force. And while the size and shape of future classrooms is difficult to predict, it is likely that classroom sizes will be smaller by 2030, with just a handful of students using portable devices and display glasses to access information while under the guidance of a teacher.

envisioning-the-future-of-educationAt the same time, classrooms are likely to be springing up everywhere, in the forms of learning annexes in apartment buildings, or home-school environments. Already, this is an option for distance education, where students and teachers are connected through the internet. With the addition of more sophisticated technology, and VR environments, students will be able to enter “virtual classrooms” and connect across vast distances.

According to Eze Vidra, the head of Google Entrepreneurs Europe: “School kids will learn from short bite-sized modules, and gamification practices will be incorporated in schools to incentivize children to progress on their own.” In short, education will become a self-directed, or (in the case of virtual environments) disembodied experienced that are less standardized, more fun, and more suited to individual needs.

Health:
medtechMany experts believe that medicine in the future is likely to shift away from addressing illness to prevention. Using thin, flexible, skin-mounted, embedded, and handheld sensors, people will be able to monitor their health on a daily basis, receiving up-to-date information on their blood pressure, cholesterol, kidney and liver values, and the likelihood that they might contract diseases in their lifetime.

All of these devices are likely to be bundled in one way or another, connected via smartphone or other such device to a person’s home computer or account. Or, as Ariel Schwatz of CoExist anticipates, they could come in the form of a “Bathroom GP”, where a series of devices like a Dr.Loo and Dr. Sink measure everything from kidney function to glucose levels during a routine trip.

doctor_bathroomBasically, these smart toilets and sinks screen for illnesses by examining your spittle, feces, urine and other bodily fluids, and then send that data to a microchip embedded inside you or on a wristband. This info is analyzed and compared to your DNA patterns and medical records to make sure everything is within the normal range. The chip also measures vital signs, and Dr Mirror displays all the results.

However, hospitals will still exist to deal with serious cases, such as injuries or the sudden onset of illnesses. But we can also expect them to be augmented thanks to the incorporation of new biotech, nanotech and bionic advances. With the development of bionic replacement limbs and mind-controlled prosthetics proceeding apace, every hospital in the future is likely to have a cybernetics or bioenhancement ward.

Prosthetic armWhat’s more, the invention of bioprinting, where 3-D printers are able to turn out replacement organic parts on demand, is also likely to seriously alter the field of medical science. If people are suffering from a failing heart, liver, kidney, or have ruined their knees or other joints, they can simply put in at the bioprinting lab and get some printed replacement parts prepared.

And as a final, encouraging point, diseases like cancer and HIV are likely to be entirely curable. With many vaccines that show the ability to not only block, but even kill, the HIV virus in production, this one-time epidemic is likely to be a thing of the past by 2030. And with a cure for cancer expected in coming years, people in 2030 are likely to view it the same way people view polio or tetanus today. In short, dangerous, but curable!

Buying/Selling:
future_money2When it comes to living in 2030, several trends are expected to contribute to people’s economic behavior. These include slow economic growth, collaborative consumption, 3-D printing, rising costs, resource scarcity, an aging population, and powerful emerging economies. Some of these trends are specific, but all of them will effect the behavior of future generations, mainly because the world of the future will be even more integrated.

As already noted, 3-D printers and scanners in the home are likely to have a profound effect on the consumer economy, mainly by giving rise to an on-demand manufacturing ethos. This, combined with online shopping, is likely to spell doom for the department store, a process that is already well underway in most developed nations (thanks to one-stop shopping).

sharing economy brandHowever, the emergence of the digital economy is also creating far more in the way of opportunities for micro-entrepreneurship and what is often referred to as the “sharing economy”. This represents a convergence between online reviews, online advertising of goods and services, and direct peer-to-peer buying and selling that circumvents major distributors.

This trend, which is not only reaching back in time to reestablish a bartering economy, but is also creating a “trust metric”, whereby companies, brand names, and even individuals are being measured by to their reputation, which in turn is based on their digital presence and what it says about them. Between a “sharing economy” and a “trust economy”, the economy of the future appears highly decentralized.

bitcoinFurther to this is the development of cryptocurrencies, a digital medium of exchange that relies solely on consumer demand to establish its value – not gold standards, speculators or centralized banks. The first such currency was Bitcoin, which emerged in 2009, but which has since been joined by numerous others like Litecoin, Namecoin, Peercoin, Ripple, Worldcoin, Dogecoin, and Primecoin.

In this especially, the world of 2030 is appearing to be a very fluid place, where wealth depends on spending habits and user faith alone, rather than the power of governments, financial organizations, or centralized bureaucracies. And with this movement into “democratic anarchy” underway, one can expect the social dynamics of nations and the world to change dramatically.

Space Travel!:
space_cameraThis last section is of such significance that it simply must end with an exclamation mark. And this is simply because by 2030, many missions and projects that will pave the way towards a renewed space age will be happening… or not. It all comes down to whether or not the funding is made available, public interest remains high, and the design and engineering concepts involved hold true.

However, other things are likely to become the norm, such as space tourism. Thanks to visionaries like World View and Richard Branson (the pioneer of space tourism with Virgin Galactic), trips to the lower atmosphere are likely to become a semi-regular occurrence, paving the way not only for off-world space tourism, but aerospace transit across the globe as well.

asteroid_neo_studyPrivate space exploration will also be in full-swing, thanks to companies like Google’s Space X and people like Elon Musk. This year, Space X is preparing for the first launch of it’s Falcon Heavy rocket, a move which will bring affordable space flight that much closer. And by 2030, affordability will be the hallmarks of private ventures into space, which will likely include asteroid mining and maybe the construction of space habitats.

2030 is also the year that NASA plans to send people to Mars, using the Orion Multi-Purpose Crew Vehicle and a redesigned Saturn V rocket. Once there, the crew will conduct surface studies and build upon the vast legacy of the Spirit, Opportunity and Curiosity Rovers to determine what Mars once looked like. This will surely be a media event, the likes of which has not been seen since the Moon Landing.

Mars_OneSpeaking of media events, by 2030, NASA may not even be the first space agency or organization to set foot on Mars. Not if Mars One, a nonprofit organization based in the Netherlands, get’s its way and manages to land a group of colonists there by 2023. And they are hardly alone, as Elon Musk has already expressed an interest in establishing a colony of 80,000 people on the Red Planet sometime in the future.

And Inspiration Mars, another non-profit organization hosted by space adventurist Dennis Tito, will have already sent an astronaut couple on a round-trip to Mars and back (again, if all goes as planned). The mission, which is currently slated for 2018 when the planets are in alignment, will therefore be a distant memory, but will serve as an example to all the private space ventures that will have followed.


In addition to Mars, one-way trips are likely to be taking place to other celestial bodies as well. For instance, Objective Europa – a non-profit made up of  scientists, conceptual artists, and social-media experts – plans to send a group of volunteers to the Jovian moon of Europa as well. And while 2030 seems a bit soon for a mission, it is likely that (if it hasn’t been scrapped) the program will be in the advanced stages by then.

NASA and other space agencies are also likely to be eying Europa at this time and perhaps even sending ships there to investigate the possibility of life beneath it’s icy surface. Relying on recent revelations about the planet’s ice sheet being thinnest at the equator, a lander or space penetrator is sure to find its way through the ice and determine once and for all if the warm waters below are home to native life forms.

europa-lander-2By 2030, NASA’s MAVEN and India’s MOM satellites will also have studied the Martian atmosphere, no doubt providing a much fuller picture of its disappearance. At the same time, NASA will have already towed an asteroid to within the Moon’s orbit to study it, and begun constructing an outpost at the L2 Lagrange Point on the far side of the Moon, should all go as planned.

And last, but certainly not least, by 2030, astronauts from NASA, the ESA, and possibly China are likely to be well on their way towards the creation of a permanent outpost on the Moon. Using a combination of 3-D printing, robots, and sintering technology, future waves of astronauts and settlers will have permanent domes made directly out of regolith with which to conduct research on the Lunar surface.

ESA_moonbaseAll of these adventures will help pave the way to a future where space tourism to other planets, habitation on the Moon and Mars, and ventures to the asteroid belt (which will solve humanity’s resource problem indefinitely), will all be the order of the day.

Summary:
To break it all down succinctly, the world of 2030 is likely to be rather different than the one we are living in right now. At the same time though, virtually all the developments that characterize it – growing populations, bigger cities, Climate Change, alternative fuels and energy, 3-D printing, cryptocurrencies, and digital devices and communications – are already apparent now.

Still, as these trends and technologies continue to expand and are distributed to more areas of the world – not to mention more people, as they come down in price – humanity is likely to start taking them for granted. The opportunities they open, and the dependency they create, will have a very deterministic effect on how people live and how the next generation will be shaped.

All in all, 2030 will be a  very interesting time because it will be here that so many developments – the greatest of which will be Climate Change and the accelerating pace of technological change – will be on the verge of reaching the tipping point. By 2050, both of these factors are likely to come to a head, taking humanity in entirely different directions and vying for control of our future.

Basically, as the natural environment reels from the effects of rising temperatures and an estimated CO2 concentration of 600 ppm in the upper atmosphere, the world will come to be characterized by famine, scarcity, shortages, and high mortality. At the same time, the accelerating pace of technology promises to lead to a new age where abundance, post-scarcity and post-mortality are the norm.

So in the end, 2030 will be a sort of curtain raiser for the halfway point of the 21st century, during which time, humanity’s fate will have become largely evident. I’m sure I’m not alone in hoping things turn out okay, because our children are surely expecting to have children of their own, and I know they would like to leave behind a world the latter could also live in!

News From Space: Luna Rings and Spidersuits!

space_cameraSpace is becoming a very interesting place, thanks to numerous innovations that are looking ahead to the next great leap in exploration. With the Moon and Mars firmly fixed as the intended targets for future manned missions, everything from proposed settlements and construction projects are being plotted, and the requisite tools are being fashioned.

For instance, the Shimizu Corporation (the designers of the Shimizu Mega-City Pyramid), a Japanese construction firm, has proposed a radical idea for bringing solar energy to the world. Taking the concept of space-based solar power a step further, Shimizu has proposed the creation of a “Luna Ring” – an array of solar cells around the Moon’s 11000 km (6800 mile) equator to harvest solar energy and beam it back to Earth.

lunaringThe plan involves using materials derived from lunar soil itself, and then using them to build an array that will measure some 400 km (250 miles) thick. Since the Moon’s equator receives a steady amount of exposure to the Sun, the photovoltaic ring would be able to generate a continuous amount of electricity, which it would then beam down to Earth from the near side of the Moon.

It’s an ambitious idea that calls for assembling machinery transported from Earth and using tele-operated robots to do the actual construction on the Moon’s surface, once it all arrives. The project would involve multiple phases, to be spread out over a period of about thirty years, and which relies on multiple strategies to make it happen.

lunaring-1For example, the firm claims that water – a necessary prerequisite for construction – could be produced by reducing lunar soil with hydrogen imported from Earth. The company also proposes extracting local regolith to fashion “lunar concrete”, and utilizing solar-heat treatment processes to fashion it into bricks, ceramics, and glass fibers.

The remotely-controlled robots would also be responsible for other construction tasks, such as excavating the surrounding landscape, leveling the ground, laying out solar panel-studded concrete, and laying embedded cables that would run from the ring to a series of transmission stations located on the Earth-facing side of the Moon.

space-based-solarpowerPower could be beamed to the Earth through microwave power transmission antennas, about 20 m (65 ft) in diameter, and a series of high density lasers, both of which would be guided by radio beacons. Microwave power receiving antennas on Earth, located offshore or in areas with little cloud cover, could convert the received microwave power into DC electricity and send it to where it was needed.

The company claims that it’s system could beam up to 13,000 terawatts of power around-the-clock, which is roughly two-thirds of what is used by the world on average per year. With such an array looming in space, and a few satellites circling the planet to pick up the slack, Earth’s energy needs could be met for the foreseable future, and all without a single drop of oil or brick of coal.

The proposed timeline has actual construction beginning as soon as 2035.

biosuitAnd naturally, when manned missions are again mounted into space, the crews will need the proper equipment to live, thrive and survive. And since much of the space suit technology is several decades old, space agencies and private companies are partnering to find new and innovative gear with which to equip the men and women who will brave the dangers of space and planetary exploration.

Consider the Biosuit, which is a prime example of a next-generation technology designed to tackle the challenges of manned missions to Mars. Created by Dava Newman, an MIT aerospace engineering professor, this Spiderman-like suit is a sleeker, lighter alternative to the standard EVA suits that weigh approximately 135 kilograms (300 pounds).

biosuit_dava_newmanFor over a decade now, Newman has been working on a suit that is specifically designed for Mars exploration. At this year’s TEDWomen event in San Francisco, she showcased her concept and demonstrated how its ergonomic design will allow astronauts to explore the difficult terrain of the Red Planet without tripping over the bulk they carry with the current EVA suits.

The reason the suit is sleek is because it’s pressurized close to the skin, which is possible thanks to tension lines in the suit. These are coincidentally what give it it’s Spiderman-like appearance, contributing to its aesthetic appeal as well. These lines are specifically designed to flex as the astronauts ends their arms or knees, thus replacing hard panels with soft, tensile fabric.

biosuit1Active materials, such as nickel-titanium shape-memory alloys, allow the nylon and spandex suit to be shrink-wrapped around the skin even tighter. This is especially important, in that it gets closer Newman to her goal of designing a suit that can contain 30% of the atmosphere’s pressure – the level necessary to keep someone alive in space.

Another benefit of the BioSuit is its resiliency. If it gets punctured, an astronaut can fix it with a new type of space-grade Ace Bandage. And perhaps most importantly, traditional suits can only be fitted to people 5′ 5″ and taller, essentially eliminating short women and men from the astronaut program. The BioSuit, on the other hand, can be built for smaller people, making things more inclusive in the future.

Mars_simulationNewman is designing the suit for space, but she also has some Earth-bound uses in mind . Thanks to evidence that showcases the benefits of compression to the muscles and cardiovascular system, the technology behind the Biosuit could be used to increase athletic performance or even help boost mobility for people with cerebral palsy. As Newman herself put it:

We’ll probably send a dozen or so people to Mars in my lifetime. I hope I see it. But imagine if we could help kids with CP just move around a little bit better.

With proper funding, Newman believes she could complete the suit design in two to three years. It would be a boon to NASA, as it appears to be significantly cheaper to make than traditional spacesuits. Funding isn’t in place yet, but Newman still hopeful that the BioSuit will be ready for the first human mission to Mars, which are slated for sometime in 2030.

In the meantime, enjoy this video of the TEDWomen talk featuring Newman and her Biosuit demonstration:

Climate News: World’s Most Potent Greenhouse Gas Found

NASA_global_warming_predFor over a century now, scientists have understood the crucial link that lies between greenhouse gases and the effect known as “Global Warming”. For decades, scientists have been focused on the role played by carbon dioxide and methane gas, the two principle polluters that are tied to human behavior and the consequences of our activities.

But now, a long-lived greenhouse gas, more potent than any other, has been discovered in the upper atmosphere by chemists at the University of Toronto. It’s known as Perfluorotributylamine (PFTBA), a gas that has a radiative efficiency of 0.86 – which is one measure of a chemical’s effectiveness at warming the climate (expressed in parts per million).

upper_atmosphereAt present, the biggest contributor to climate change is carbon dioxide, mainly because its concentrations are so high — 393.1 parts per million in 2012 and growing, thanks to human activity. However, many other gases contribute to this trend – such as nitrogen trifluoride and various chloroflurocarbons (CFCs) – but are less involved in the overall warming effect because their concentrations are lower.

According to the research article, which appeared in a recent issue of Geophysics Research Letters, the concentrations of PFTBA are very small — about 0.18 parts per trillion by volume in the atmosphere (at least in Toronto, where it was detected). But even though the overall contribution of PFTBA is comparatively small, its effect is “on the same scale as some of the gases that the monitoring community is aware of.”

Toronto Skyline With SmogAccording to 3M, a producer of PFTBA, the chemical has been sold for more than 30 years for the purpose of cooling semiconductor processing equipment and specialized military equipment, much in the same way that CFCs have been used. It is effective at transferring heat away from electronic components, and is stable, non-flammable, non-toxic, and doesn’t conduct electricity.

The chemical has an average lifespan of about 500 years in the lower atmosphere, and also like CFC’s, it has long been known to have the potential to cause damage to the ozone layer. But up until now its ability to trap heat in the atmosphere had not been measured, nor had it been detected in the atmosphere. The reason PFTBA is so potent compared to other gases is that it absorbs heat that would normally escape from the atmosphere.

electromagnetic-spectrumHeat, or infrared radiation comes, in different colors, and each greenhouse gas is only able to absorb certain colors of heat. PFTBA is different in that it manages to absorb colors that other greenhouse gases don’t. It was after some was discovered on the university grounds by Professor Scott Mabury that his team began to consider whether any had made it into the atmosphere as well.

Shortly thereafter, they conducted a series of tests to measure the radiative efficiency of the chemical and then began looking for samples of it in the air. This involved deploying air pumps to three locations – including the University of Toronto campus, Mt. Pleasant Cemetery and Woodbine Beach. The samples were then condensed and concentrated, and the PFTBA separated by weight.

airpollution1The end result was that PFTBA was found in all samples, including those upwind from the University of Toronto, suggesting that it wasn’t just coming from the chemistry building. However, the measurements were local and therefore not representative of the global average concentrations of the chemical. Still, its discovery is an indication that dangers might exist.

According to Angela Hong, a PhD student at the UofT department of chemistry and the lead author of the paper, this danger lies in the combined effect PFTBA could have alongside other gases:

If you’re suddenly going to add a greenhouse gas and it absorbs in that region. it’s going to be very potent.

Its effect is far more intense if its effect per molecule is considered, since it is about 15 times heavier than carbon dioxide. What’s more, PFTBA survives hundreds of years in the atmosphere, which means its effects are long-lasting. Fortunately, its use has been regulated under a U.S. Environmental Protection Agency program that promotes alternatives to chemicals that deplete the ozone layer.

pftba-toronto-537x402In addition, chemicals that deplete the ozone layer are recognized by the Kyoto Protocols. As such, it should be an easy matter (from a legal standpoint anyway) to legislate against its continued use. As 3M indicated in a recent press statement:

That regulation stipulates that PFCs [the class of chemical that PFTBA belongs to] should be used only where there are no other alternatives on the basis of performance and safety. 3M adheres to that policy globally.

It added that the company “has worked to limit the use of these materials to non-emissive applications” and emphasized that the concentration of PFTBA found in the atmosphere is very low.

????????????????Nevertheless, this represents good news and bad news when it comes to the ongoing issue of Climate Change. On the one hand, early detection like this is a good way of ensuring that gases that contribute to the problem can be identified and brought under control before they become a problem. On the other, it shows us that when it comes to warming, there are more culprits than previously expected to contributing to it.

According to the most recent IPCC report, which was filed in 2012, the likelihood of us reaching a critical tipping point – i.e. the point of no return with warming – this century is highly unlikely. But that still leaves plenty of room for the problem to get worse before it gets better. One can only hope we get our acts together before it’s too late.

The Future is Here: Wind Drones and Clean Buildings

wind_powerIt’s no secret that wind power is one of main clean forms of energy that is being considered as a viable alternative to coal, oil and gas. But much like solar, tidal and geothermal, the method has some flaws that is preventing it from being adopted in a more widespread fashion. However, as an infinitely renewable source of energy, it likely just a matter of time before technical developments lead to its wholesale use.

The first challenge has to do with size. Currently, wind farms are massive operations, and many designers think they need to continue to get bigger in order to generate the kinds of electricity we currently need. However, a Netherlands-based startup named Ampyx Power is looking in another direction: an airborne wind turbine that they think could capture the same amount of energy as a large operation.

ampyx-power-powerplane-6-topview-1Basically, their design is a small glider plane attached by cable to a generator, which is then deployed into the air and flies in figure eights. As it moves, the glider pulls on the capable, and the generator converts the movement to electricity. Since it isn’t attached to a tower, it can soar nearly 2,000 feet in the air, catching stronger winds that produce about eight times more energy than the lower-altitude breezes that reach a normal wind turbine.

So in addition to being able to produce more power than a typical wind farm, it costs significantly less than its competitor. The average wind farm weighs about 120 metric tons, while the glider system weighs in at a mere 363 kilograms (800 pounds). And in addition to being cheaper than other renewables, the process may even be cheaper than coal.

wind-power-660As Wolbert Allaart, the startup’s managing director, put it:

We’re replacing tons of steel and concrete. It’s a huge materials reduction, and we can produce the same amount of power. That obviously has an effect on cost as well… The whole reason why we’re doing this is because we think we can get the cost of a kilowatt-hour well below the price of coal.

And Ampyx is hardly alone in developing the technology. In fact, their design is similar to California-based Makani Power’s glider. This company was acquired by Google earlier this year, while Ampyx raised the necessary capital via a crowdfunding campaign. And though there are some differences in the design and methods employed, both companies dream of a day when wind will replace coal and other dirty means.

ampyx-power1Because the planes are so efficient, places that might not have worked for wind power in the past – like forests, where trees catch and redirect the wind – could be a fit for the system, so the market is wide open. And given his country’s growing interest in wind power, Allaart hopes to introduce it to the domestic market very soon:

In Holland, where we’re based, we now have a 4.3 billion Euro subsidy scheme for offshore wind. People are starting to wonder already, if we have a technology being developed in our own country that could provide offshore wind at more or less competitive price with coal, why on Earth are we still subsidizing this so heavily? How fast this grows will depend on political will.

pertamina-energy-tower4site-aerialsomAnother very cool wind-related story comes from Jakarta, where a massive tower is being planned that will be capable of generating all its own power. It’s known as the Pertamina Energy Tower, the proposed headquarters of the Pertamina power company. And while the proposed building will be 99 stories in height, it will also gather all its power from wind, solar, and geothermal energy.

When it comes to its wind operations, the building’s height plays to its advantage. At the top of the building, a funnel captures wind, sucks it inside, and speeds it up to run a series of vertical wind turbines. In this respect, the building operates like a giant, vertical wind tunnel. Solar energy will also be incorporated through panels that will cover the roofs of other buildings on the new campus.

pertamina-energy-tower2energy-ribbonsomBut perhaps the most impressive feat comes in the form of geothermal, a type of energy that’s uniquely suited for Indonesia because it’s a volcanic island chain. Geothermal systems in Indonesia can tap directly into superheated sources of subterranean steam with a single pipe, unlike typical systems that are more complicated and expensive to engineer.

Scott Duncan, the director of Pertamina’s architecture firm – Skidmore, Owings & Merrill LLP (SOM) – who led the project, describes it this way:

It would essentially provide an unlimited energy source for the tower and campus and could make the tower the world’s first energy-positive supertall building.

pertamina-energy-tower6In addition to meeting this clean-energy trifecta, the design of the tower is focused on saving energy as much generating it. Sun-shading “leaves” on two sides of the building cut glare and shade the brightest sunlight while still keeping the inside of the offices bright enough to avoid most artificial lighting. Instead of power-sucking air conditioners, the building uses water-based radiant cooling systems to keep the temperatures even.

Along with other strategies, the energy-saving design elements mean that the campus – which will include a mosque, a performing arts and exhibition center, and sports facilities along with the office space – can keep energy use low enough that renewable power may be able to cover its entire energy needs. In short, the building could prove to be a model of energy-independence.

pertamina-energy-tower5However, the motivation for this project go beyond the altruistic, and involve a good many practical considerations. For starters, Jakarta still has an unreliable power grid, and if the campus generates its own power, work and play won’t get interrupted. The buildings also won’t have to rely on diesel fuel generators if the city’s power goes down.

The technology is expected to be adopted elsewhere, particularly China where wind power is expanding all the time. Indonesia, despite its easy access to geothermal energy, is not the windiest place in the world. Cities that are strategically located along coastlines or in elevated regions would find the wind tunnel feature that much more useful, reducing their dependence on the other two forms of energy.

shanghai_towerWhat’s more, this building is in many respects what one would call an Arcology, and just happens to be the second one being planned for construction in the world today. The other, un-coincidentally enough, is China’s Shanghai Tower, a building that is one-third green space and a transparent second skin that surrounds the city in a protective air envelope that controls its internal temperature.

And with global energy prices increasing, the sources of easily-accessible oil disappearing, and atmospheric CO2 levels steadily rising, we can expect to see more buildings like these ones going up all around the world. We’re also likely to see more creative and innovative forms of power generation popping up in our backyards. Much like peak oil, centralized grids and dependence on unclean energy is disappearing…

The Future is Bright: Positive Trends to Look For in 2014

Colourful 2014 in fiery sparklersWith all of the world’s current problems, poverty, underdevelopment, terrorism, civil war, and environmental degradation, it’s easy to overlook how things are getting better around the world. Not only do we no longer live in a world where superpowers are no longer aiming nuclear missiles at each other and two-thirds of the human race live beneath totalitarian regimes; in terms of health, mortality, and income, life is getting better too.

So, in honor of the New Year and all our hopes for a better world, here’s a gander at how life is improving and is likely to continue…

1. Poverty is decreasing:
The population currently whose income or consumption is below the poverty line – subsisting on less than $1.25 a day –  is steadily dropping. In fact, the overall economic growth of the past 50 years has been proportionately greater than that experienced in the previous 500. Much of this is due not only to the growth taking place in China and India, but also Brazil, Russia, and Sub-Saharan Africa. In fact, while developing nations complain about debt crises and ongoing recession, the world’s poorest areas continue to grow.

gdp-growth-20132. Health is improving:
The overall caloric consumption of people around the world is increasing, meaning that world hunger is on the wane. Infant mortality, a major issue arising from poverty, and underdevelopment, and closely related to overpopulation, is also dropping. And while rates of cancer continue to rise, the rate of cancer mortality continue to decrease. And perhaps biggest of all, the world will be entering into 2014 with several working vaccines and even cures for HIV (of which I’ve made many posts).

3. Education is on the rise:
More children worldwide (especially girls) have educational opportunities, with enrollment increasing in both primary and secondary schools. Literacy is also on the rise, with the global rate reaching as high as 84% by 2012. At its current rate of growth, global rates of literacy have more than doubled since 1970, and the connections between literacy, economic development, and life expectancy are all well established.

literacy_worldwide4. The Internet and computing are getting faster:
Ever since the internet revolution began, connection speeds and bandwidth have been increasing significantly year after year. In fact, the global average connection speed for the first quarter of 2012 hit 2.6 Mbps, which is a 25 percent year-over-year gain, and a 14 percent gain over the fourth quarter of 2011. And by the second quarter of 2013, the overall global average peak connection speed reached 18.9 Mbps, which represented a 17 percent gan over 2012.

And while computing appears to be reaching a bottleneck, the overall increase in speed has increased by a factor of 260,000 in the past forty years, and storage capacity by a factor of 10,000 in the last twenty. And in terms of breaking the current limitations imposed by chip size and materials, developments in graphene, carbon nanotubes, and biochips are promising solutions.

^5. Unintended pregnancies are down:
While it still remains high in the developing regions of the world, the global rate of unintended pregnancies has fallen dramatically in recent years. In fact, between 1995 and 2008, of 208 billion pregnancies surveyed in a total of 80 nations, 41 percent of the pregnancies were unintended. However, this represents a drop of 29 percent in the developed regions surveyed and a 20 percent drop in developing regions.

The consequences of unintended pregnancies for women and their families is well established, and any drop presents opportunities for greater health, safety, and freedom for women. What’s more, a drop in the rate of unwanted pregnancies is surefire sign of socioeconomic development and increasing opportunities for women and girls worldwide.

gfcdimage_06. Population growth is slowing:
On this blog of mine, I’m always ranting about how overpopulation is bad and going to get to get worse in the near future. But in truth, that is only part of the story. The upside is while the numbers keep going up, the rate of increase is going down. While global population is expected to rise to 9.3 billion by 2050 and 10.1 billion by 2100, this represents a serious slowing of growth.

If one were to compare these growth projections to what happened in the 20th century, where population rose from 1 billion to just over 6, they would see that the rate of growth has halved. What’s more, rates of population growth are expecting to begin falling in Asia by 2060 (one of the biggest contributors to world population in the 20th century), in Europe by 2055, and the Caribbean by 2065.

Population_curve.svgIn fact, the only region where exponential population growth is expected to happen is Africa, where the population of over 1 billion is expected to reach 4 billion by the end of the 21st century. And given the current rate of economic growth, this could represent a positive development for the continent, which could see itself becoming the next powerhouse economy by the 2050s.

7. Clean energy is getting cheaper:
While the price of fossil fuels are going up around the world, forcing companies to turn to dirty means of oil and natural gas extraction, the price of solar energy has been dropping exponentially. In fact, the per capita cost of this renewable source of energy ($ per watt) has dropped from a high of $80 in 1977 to 0.74 this past year. This represents a 108 fold decrease in the space of 36 years.

solar_array1And while solar currently comprises only a quarter of a percent of the planet’s electricity supply, its total share grew by 86% last year. In addition, wind farms already provide 2% of the world’s electricity, and their capacity is doubling every three years. At this rate of increase, solar, wind and other renewables are likely to completely offset coal, oil and gas in the near future.

Summary:
In short, things are looking up, even if they do have a long way to go. And a lot of what is expected to make the world a better place is likely to happen this year. Who knows which diseases we will find cures for? Who knows what inspirational leaders will come forward? And who knows what new and exciting inventions will be created, ones which offer creative and innovative solutions to our current problems?

Who knows? All I can say is that I am eager to find out!

Towards a Cleaner Future: Solar and Wind Drones

solar_cell_galliumWith supplies of easily accessible fossil fuels diminishing, pushing us towards dirtier sources of oil and natural gas (such as tar sands and frakking), researchers are looking for ways to make renewable energy more efficient and accessible. Towards this end, they are pushing the boundaries of solar cells and wind turbines are capable of, but the constraints of land and weather limit where vast solar or wind farms can be set up.

Luckily, a UK-based company known as New Wave Energy has spent the last few years developing the technology to produce an army of power-generating drone aircraft to overcome these very problems. Basically, each craft is a 20x20m (65ft) flat surface fitted with solar panels and turbines to generate power from the sun and wind, and four small propellers that keep it aloft.

solar_dronesThe drones would be capable of flying at altitudes of up to 15,240 meters (50,000 feet), putting them far above the clouds that can obscure the sun. The propellers would allow the craft to track the course of the sun to remain in optimal position for as long as possible. At these altitudes, the wind is also more consistent and powerful, which means smaller turbines can be used in place of the giant towers necessary down near the ground.

In terms of transmitting that power, the key is in the use of microwaves. In essence, power from the drones would be beamed down as a low-energy microwave and collected by antenna arrays on the ground. These antennas can then be used to turn the electromagnetic radiation into usable DC power and then send it to where it is needed.

solar_drones1One of the benefits of this design is that the proposed drone power plants wouldn’t need to land to refuel themselves. Supposedly, they will be able to power themselves entirely with the energy generated on-board, and still produce 50kW of power. This that means several thousand drones would be needed to power a large city of 205,000 homes.

However, these swarms of robotic power plants aren’t just a way to replace the power infrastructure we already have. They could be used to augment our current power supplies as demand increases, removing the need to expand on large, expensive power plants. Also, they bring power to remote areas with poor service, or to restore power in regions affected by natural disasters.

solar_panelThus, the cost of building and deploying the drones will determine whether or not that’s feasible. At present, the company plans to raise about $500,000 on Kickstarter to fund the construction of a prototype for testing and marketing. If this campaign does turn out to be successful, the first flying power plant could be aloft within six months.

Combined with other improvements that are making wind and solar power more efficient and affordable, and future prospects for space-based solar power (SBSP) that are being made possible thanks to space startups like Google X, we could be looking at a near-future where solar and wind meet the lion’s share of our energy requirements.

Climate Crisis: Illustrative Video of Impending Disaster

IPCC2012_vid3Recently, the United Nation’s Intergovernmental Panel on Climate Change released its 2012 report, which contained some rather stark observations and conclusions. In addition to reconfirming what the 2007 report said about the anthropogenic effects of CO2 emissions, the report also tackled speculation about the role of Solar Forcing and Cosmic Rays in Global Warming, as well as why warming has been proceeding slower than previously expected.

In the end, the report concluded that certain natural factors, such as the influence of the Sun and Cosmic Rays in “seeding clouds”, were diminishing, and thus have a negative effect on the overall warming situation. In spite of that, global temperatures continue to increase, due to the fact that humanity’s output of greenhouse gases (particularly CO2) has not slowed down one bit in recent years.

IPCC2012_vidThe report also goes on to explain detailed scenarios of what we can expect in the coming decades, in extreme and extensive detail. However, for those who have neither the time, patience, or technical knowledge that wade through the report, a helpful video has been provided. Courtesy of Globaia,this four minute video sums up the facts about Climate Change and how it is likely to impact Earth’s many inhabitants, human and otherwise.

Needless to say, the facts are grim. By 2050, if humans remain on their current path, global temperatures will rise more than two degrees Celsius above what it’s been for most of human history. By 2100, it might even climb four degrees. The IPCC report, and this video, confirm what we’ve been hearing everywhere. Arctic sea ice is disappearing, sea levels are rising, storms are getting more destructive, and the full extent of change is not even fully known.

IPCC2012_vid6As the organization that put together this data visualization along with other scientists, Globaia says that it created this video as a call to action for policymakers. Felix Pharand-Deschenes, who founded the Canadian nonprofit company and animated the video, claims that:

If we are convinced of the seriousness of the situation, then political actions and technological fixes will result,” says  “But we have to change our minds first. This is the reason why we try to translate our terrestrial presence and impacts into images–along with the physical limits of our collective actions.

But of course, there’s still hope. As Pharand-Deschenes went on to say, if we can summon up a “war effort,” and work together the way World War II-era citizens did, we could still manage to the social systems that are largely responsible for the problem. This includes everything from transportation and energy to how we grow our food, enough to stay below a two degree rise.

IPCC2012_vid5Of course, this is no small task. But as I love to remind all my readers, research and efforts are happening every day that is making this a reality. Not only is solar, wind and tidal power moving along by leaps and bounds, becoming profitable as well as affordable, we are making great strides in terms of Carbon Capture technology, alternative fuels, and eco-friendly living that are expected to play a huge role in the coming decades.

And though it is often not considered, the progress being made in space flight and exploration also play a role in saving the planet. By looking to make the process of sending ships and satellites into space cheaper, concepts like Space-Based Solar Power (SBSP) can become a reality, one which will meet humanity’s immense power demands in a way that is never marred by weather or locality.

IPCC2012_vid4Combined with sintering and 3-D printing, asteroid prospecting and mining could become a reality too in a few decades time. Currently, it is estimated that just a few of the larger rocks beyond the orbit of Mars would be enough to meet Earth’s mineral needs indefinitely. By shifting our manufacturing and mining efforts offworld with the help of automated robot spacecraft and factories, we would be generating far less in the way of a carbon footprint here on Earth.

But of course, the question of “will it be enough” is a burning one. Some scientists say that an increase of even two degrees Celsius is more than Earth’s creatures can actually handle. But most agree that we need to act immediately to prepare for the future, and that one of the things standing in the way of action is the fact that the problem seems so abstract. Luckily, informational videos like this one present the problem is clear and concise terms.

ipcc2012_vid1The IPCC reports that we only have 125 billion tons of CO2 left to burn before reaching the tipping point, and at current rates, that could happen in just over two decades. Will we have a fully renewable-powered, zero-carbon world by then? Who knows? The point is, if we can get such a task underway by then, things may get worse before they get better, but they will improve in the end. Compared to the prospect of extinction, that seems like a bargain!

In the meantime, check out the video – courtesy of Globaia and the International Geosphere-Biosphere Programme (IGBP) – and try to enjoy it despite its gloomy predictions. I assure you, it is well worth it!

Climate Crisis: The Ongoing Case of Big Subsidies

Pollution over Mexico CityOne of the most recurring talking points in the Climate Change debate is the issue of renewable energy. Particularly, those who take issue with proposed changes for dealing with the problem continue to cite how solar, wind and tidal power are not viable replacements at this juncture. While this talking point is a convenient way of dismissing needing reforms, it neglects two self-evident realities.

For one, it ignores the immense amount of progress being made in the fields of renewable energy. Whereas inefficiency and high costs remained as stumbling blocks in previous decades, an exponential drop in costs and a rise in efficiency has made solar increasingly attractive for power companies in recent years. Wind and tidal are in similar situations, with countries like Scotland and the United Arab Emirates leading the way in making them profitable.

airpollutionSecond, it ignores the fact that developed nations continue to stymie growth in renewables by the continued way in which they commit billions to subsidizing oil and coal. According to a new report from the Overseas Development Institute, public subsidies for fossil fuels totaled $523 billion in 2011. That’s six times the level of support for the renewable energy industry, despite those technologies being less mature than oil and coal.

Among richer countries, the top 11 heaviest carbon emitters spent $74 billion in subsidies in 2011, with Russia, the United States, Australia, Germany, and the United Kingdom leading the way. In the U.S., these included a $1 billion fuel tax exemption for farmers, $1 billion for the Strategic Petroleum Reserve, and $500 million for fossil fuel R&D.

oil_slickIn so doing, these governments are:

…shooting themselves in both feet [by subsidizing] the very activities that are pushing the world towards dangerous climate change… [and] creating barriers to investment in low-carbon development.

According to the British think-tank, this works out a spending of $112 per adult in these nations. But of course, the richest nations are not the only offenders, which nations like Pakistan, Egypt, and Indonesia spending more than twice as much on fossil fuel subsidies as on health. The ODI says the poorest 20% of households typically receive just 7% of overall handouts.

pollution_powerplantBut the ODI may be underestimating the true size of the subsidies in the U.S., depending on how you look at it. Earlier this year, the International Monetary Fund calculated subsidies at $502 billion, a figure which includes the true cost of carbon emissions calculated at a price of $25 a ton. By that measure, global subsidies equal $1.9 trillion.

The report also advises that governments should cut handouts to oil and coal as soon as they can and begin looking after the genuinely poor:

Phasing out fossil fuel subsidies would create a win-win scenario. It would eliminate the perverse incentives that drive up carbon emissions, create price signals for investment in a low-carbon transition and reduce pressure on public finances.

solar_cell1A timely and sound recommendation, and one which cuts to the heart of the matter. In order to address the problem of Climate Change, we must not only adopt better methods for meeting our needs, we must acknowledge the truth of the issue. At the same time, we must acknowledge how ending these subsidies, or redistributing them, would alter the current balance of power on the whole issue of energy.

It’s one thing to claim that alternative methods are unviable when the playing field is level, but since it is not, the argument is essentially hypocrisy. By continuing to finance fossil fuels and coal, we are ensuring that clean energy will remain underdeveloped as an alternative, and hence undermining any chance it has at becoming a true alternative.

So the next time someone tells you that solar or other means of renewable energy are at least 50 years away, or that gas and coal are the only economical means of meeting our energy needs, be sure to ask them why we need to spend half a trillion dollars on them annually.

Typhoon Haiyan From Space

typhoon_haiyanEarlier this month, the Super Typhoon Haiyan smashed into the island nation of the Philippines, leaving an enormous amount of death and destruction in its wake. According to NASA, the typhoon struck with winds that exceeded 379 kilometers per hour (235 mph), while the U.S. Navy Joint Typhoon Warning Center indicates that it has since sustained wind speeds of over 315 kilometers per hour (95 MPH).

Classified as a Category 5 monster storm on the U.S. Saffir-Simpson scale, Haiyan is reported to be the largest and most powerful storm ever to make landfall in recorded human history. The current estimates claim that some 5000 people have died so far, with the final toll expected to be far higher.

haiyan_8_november_2013_0019_utc_0-566x580Given the enormous scale of this typhoon, many of the clearest pictures of it have come from space. Since it first made landfall on Friday, November 8th, many detailed images have been captured by NASA, the Russian Space Agency, the India’s newly-launched Mars Orbiter Mission (MOM), and even from the ISS – courtesy of astronaut Karen Nyberg.

According to NASA, the most detailed data on the storm came from the Tropical Rainfall Measuring Mission (TRMM) satellite, which captured visible, microwave and infrared data on the storm just as it was crossing the island of Leyte in the central Philippines. In addition to gauging wind speed, the satellite was also able to measure precipitation rates and temperature fluctuations.

typhoon_haiyan1Far from simply documenting this tragedy, the high resolution imagery and precise measurements provided by these and other satellites have been absolutely essential to tracking this storm and providing advance warning. Whereas thousands have died in the effected areas, some 800,000 more have been evacuated from the central region of the country.

Coincidentally, NASA’s Goddard Flight Center has just finished assembling the next generation weather satellite known as the Global Precipitation Measurement (GPM), an observatory that is scheduled to replace the Tropical Rainfall Measuring Mission. GPM is equipped with advanced, higher resolution radar instruments and is vital to the continued effort of providing forecasts and advance warning of extreme super storms.

typhoon_haiyan2In the midst of tragedies like Hurricane Sandy and Haiyan, not to mention the escalating risk of super-storms associated with Climate Change, it is good to know that there are silver linings, such as advanced warning and sophisticated instruments that can keep us apprised of the threats we face. For more information on Super Typhoon Haiyan and how you can aid in the recovery, check out the Internationa Red Cross’ website.

And be sure to check out this video of Haiyan as it made landfall, as captured by the Russian weather satellite Electro-L:

Climate Crisis: “Carbon Buster” Bricks

carbon_busterReducing our “carbon footprint” as a society – i.e. finding ways to consume less energy and generate less pollution – is at an all time high in the industrialized world. But for researchers and scientists hoping to avert the worst effects of Climate Change, the real challenge is finding ways to meet human needs that will either be carbon-neutral, or that consume more than they create.

This is the logic behind process like Carbon Capture, the “Smog Vacuum” and now, carbon negative building materials such as the “Carbon Buster”. Basically, it’s a brick that’s partially composed  of wood from old doors and windows (35% to be exact). In addition, it contains nasty pollutants that used to go into the air. But most important of all, more CO2 is locked inside than was emitted during the brick’s production and transport.

carbon_buster1The block is manufactured by a company in the east of England known as Lignacite, a company that has been making products from wood for 65 years. Lignacite recently partnered with another company named Carbon 8, another Suffolk-based company that converts noxious fumes from waste incinerators and combined with CO2, cement and sand to create aggregate.

To create the bricks, this aggregate is mixed with wood shavings from Lignacite’s plant, and Carbon Busters are born. Each one is composed of 50% recycled material and locks in about 14 kg (31 pounds) of carbon dioxide, which includes the CO2 the original trees took in during photosynthesis, and the CO2 captured in the aggregate-making process.

Carbon_Negative_CementGranted, the bricks aren’t exactly aesthetically appealing. But they are relatively lightweight, suitable for even the biggest construction projects, and more fire-resistant than blocks made from stone, which crack and crumble at high temperatures. Since the wood inside these bricks is not exposed to oxygen, they will not burn, but simply calcify and blacken when exposed to fire.

Giles de Lotbiniere, Lignacite’s chairman, claims that so far, roughly 600 homes have been built in the Suffolk area near where the Lignacite plant is situated. He also indicated that they sell at a 5% premium compared to conventional bricks. And while there is currently resistance to using aggregate and wood-based materials on an international scale, de Lothbiniere believes the market will expand in coming years:

Over the years, we’ve wondered if we want to continue making blocks out of wood. Each time we’ve found another reason to do it. Now, with climate change, we’ve found another one.

Just two years ago, Material ConneXion unveiled its own carbon-negative product – a carbon-negative cement composed of magnesium silicate that not only requires less heating, but it is also able to absorb CO2 from the environment as it hardens.

And then there’s Hemcrete, a bio-composite, thermal walling material made from hemp, lime and water that represents an alternative to fiberglass as an insulating material. Much like these other carbon-negative materials, more CO2 is locked-up in the process of growing and harvesting the hemp than is released in the production, and the product is 100% recyclable.

Taken together, materials like these are likely to revolution the construction industry in the coming years, an industry which currently accounts for roughly 38% of the CO2 emissions in the industrialized world.
