Climate Crisis: Terraforming the Desert

green_machineNow that I’m back from my European adventure, I finally have the time to catch up on some news stories that were breaking earlier in the month. And between posting about said adventure, I thought I might read up and post up on them, since they are all quite interesting to behold. Take, for example, this revolutionary idea that calls for the creation of a rolling city that has one purpose in mind: to replant the deserts of the world.

Desertification is currently one of the greatest threats facing humanity. Every year, more than 75,000 square kilometers (46,000 square miles) of arable land turns to desert. As deserts spread – a process that is accelerating thanks to climate change and practices like clear-cutting – the UN estimates that more than 1 billion people will be directly affected. Many of them, living in places like Northern Africa and rural China, are already struggling with poverty, so the loss of farmland would be especially hard to handle.

green_machine_balloonsAs a result, scientists are looking to come up with creative solutions to the problem. One such concept is the Green Machine – a floating, self-powered platform that would act as a mobile oasis. Rolling on treads originally designed to move NASA rockets. Designed by Malka Architecture and Yachar Bouhaya Architecture for the Venice Biennial, this mobile city would roam the drylands and plant seeds in an effort to hold back the desert.

The huge platform would be mounted on sixteen caterpillar treads originally made to move NASA rockets, while giant floating balloons that hover from it capture water condensation. As the first treads roll over the soil, the machine uses a little water from the balloons to soften the ground while the last set of treads injects seeds, some fertilizer, and more water. The entire platform would run on renewable power, using a combination of solar towers, wind turbines, and a generator that uses temperature differences in the desert to creates electricity.

green_machine_cityThe machine could theoretically capture enough energy that it can self-support an entire small city onboard, complete with housing, schools, businesses, parks, and more farmland to grow produce for the local area. This city would house and support the many researchers, agronomers, workers and their families that would be needed to oversee the efforts. Similar to what takes place in oil drilling, these individuals could be flown in for periods of work that could last up to sixth weeks at a time before rotating out.

The designers were inspired by Allan Savory, who has proposed a much lower-tech version of the same process that relied on cattle to naturally till and fertilize the soil. For the architects, building on this idea seemed like a natural extension of their work. If the machine went into action at desert borders, the designers say it could help formerly barren soil produce 20 million tons of crops each year, and could even help slow climate change by capturing carbon in soil.

green_machine_terraOver time, biodiversity could also gradually return to the area. The architects are currently working on developing the project on the Moroccan side of the Sahara Desert. As Stephane Malka, founder of Malka Architecture, put it, it’s all about using the neglected parts of the world to plan for humanity’s future:

For a long time, my studio has developed work around neglected spaces of the city. Deserts are the biggest neglected space on Earth, as they represent more than 40% of the terrestrial surface. Building the Green Machine units would be able to re-green half of the desert borders and the meadows of the world, while feeding all of humanity

As to the sheer size of their massive, treaded city, the designers stressed that it was merely an extension of the challenge it is seeking to address. Apparently, if you want to halt a worldwide problem, you need a big-ass, honking machine!

The Future of Cities: eVolo’s 2014 Skyscraper Competition

3028400-slide-launchspireThe skyline of the future… Chances are, it’s something we’ve all wondered about at one time or another. Given the current rate of urban expansion, combined with population growth and environmental concerns, it’s essentially a given that cities of the future will look quite different from cities today. And when it comes time to break new ground and convert old centers, contracts will be given to those designs that can meet all of these challenges.

That’s the idea behind eVolo Magazine’s Skyscraper Competition, an annual event that for the past nine years has awarded architects and planners who create the problem-solving skyscrapers of the future. This year, over 600 entries were submitted from around the world, and top marks were given for those that addressed the problems or urban sprawl, pollution, sustainable living, and incorporated the latest in design technology.

These included the latest in renewable energy, carbon-capture technology, additive manufacturing (aka. 3D printing), and of course, the time honored concept of Paolo Soleri’s Arcology – a school of thought that merges architecture with ecology for smarter and more sustainable living. Here are just a few of the entries that received top marks in this year’s competition, which include the top three and numerous honorable mentions:

Winners:

Vernacular Versatility:
0302-0The winner of this year’s Skyscraper Competition, this entry was created of Korean-American designer Yong Ju Lee. who used the concepts of the “Hanok” and “Gagu” as his inspiration. In traditional Korean architecture, the Hanok refers to a type of house with an exposed wooden structure and tiled roof. Gagu refers to a special wooden structural element that is located directly beneath the main roof where the column meets the beam and girder and fastens them without the need for nails or additional parts.

Traditionally, this structural system has only ever been employed in the creation of single-story residences. However, modern modeling software allowed Lee to adapt this traditional system to complex high-rise structural planning to meet contemporary purposes and programs. Vernacular Versatility can open a new chapter of possibilities to bring this old construction and design tradition to the present day with efficiency and beauty.

Designed to be located within one of Korea’s busiest districts, Vernacular Versatility seeks to use a traditional design concept to combat the growing problem of urban sprawl, as well as associated health risks such as atopy and asthma, as well as addressing the destructive impacts urbanization has been having on traditional Korean culture and the environment.

Car and Shell Skyscraper:0697-0Also known as “Marinetti’s Monster” and created by Mark Talbot, Daniel Markiewicz, this concept for a “city in the sky” took home 2nd place at this year’s competition. As a solution for what to do about Detroit’s aging infrastructure, the project proposes a vertical suburban neighborhood equipped with recreational and commercial areas where three main grids (streets, pedestrian pathways, and structure) are intertwined to create a box-shaped wireframe.

Inspired by all the attempts to “save Detroit”, which is focused largely on preserving its dwindling suburban areas, Talbot and Markiewicz instead thought of building a new neighborhood within a single enormous skyscraper located in the core. Here, dozens of single-family homes are stacked into a vertical grid, new roads cross through the building, and traditional and contemporary living all plug into a framework to create a rich urban environment.

Propagate Skyscraper:
3028400-slide-propagateThis year’s third place went to Canadian designers YuHao Liu and Rui Wu for their concept of a building that would turn air pollution into construction materials and use it to gradually create the building. Relying on an alternative carbon-capture technique that employs philic resins and material processes to transform carbon dioxide into solid construction material, their building employs additional material that uses carbon dioxide as a means to self-propagate.

The building uses a simple vertical grid scaffold as a framework and takes all the ingredients it needs for material propagation from the surrounding environment. Individual living spaces are built within this gridwork, which creates open square spaces between lattices that can then be filled by tenements. Its pattern of growth is defined by environmental factors such as wind, weather, and the saturation of carbon dioxide within the immediate atmosphere.

Thus each building is a direct reflection of its environment, growing and adapting according to local conditions and cleaning as the air as it does so. Unlike conventional skyscrapers, which rely on steel frame and concrete casting, the proposed skyscraper suggests a more environmental conscious construction method, an alternative mode of occupation and ownership, and possibly a distinct organization of social relationships.

Honorable Mentions:

Climatology Tower:
??Designed by Yuan-Sung Hsiao, Yuko Ochiai, Jia-Wei Liu, Hung-Lin Hsieh and Japan and Taiwan, the Climatology Tower is a proposed skyscraper designed as a research center that evaluates urban meteorology and corrects the environment through mechanical engineering. This involves analyzing microclimates within cities as a result of the use of industrial materials, the accumulation of buildings, and the scarceness of open spaces. In order to maintain a healthy environment for the city, two main strategies are employed.

The first is Environmental Control Engineering, which consists of a system of evaluation and operational programs. Evaluation programs inspect city climates through a variety of factors such as insolation, radiation, and thermal coverage. Collected data is compared with humidity levels and then mechanical systems respond to reduce or increase the levels to optimal environmental conditions. The second is Information Expression, a system that is becoming increasingly common in East Asia.

Basically, in addition to automatically adjusting to optimal environmental conditions, data is transferred from a control center to different departments in this city. This can alert entire communities of present and upcoming environmental hazards and conditions, much as residents in major cities are currently given “smog alerts”. Climatic information is also displayed publicly, though digital networks, notifying the public on maintaining certain conditions, to preserve both energy and health.

Here-After:Here-AfterDesigned by Tsang Aron Wai Chun of Hong Kong, the Here-After project is a proposal to reuse the Ruashi copper mine located in Lubumbashi, Congo. The mine is predicted to stop production in 2020, at which time it would be abandoned, leaving as an enormous urban void surrounded by a rapidly expanding city. The Here-After projects seeks to make use of the left over space, waste soil, and sulfuric acid from the mine drainage and former copper production.

A machine will reuse the waste soil to neutralize the sulfuric acid, which in turn will be used to erode the land to be used as raw buildings blocks for the project. As the machine operates, starting from the South end, the remaining structures from the neutralization process would be reconfigured as a university campus. Throughout the building process the contour, the campus, and the public spaces would continuously change their relationships and form.

Hyper Filter Skyscraper:
hyper_filterDesigned by Umarov Alexey of Russia, the Hyper Filter Skyscraper recognizes the threat of environmental pollution and seeks to merge carbon capture technology with the building’s design. Under today’s levels of pollution, harmful substances spread over hundreds of kilometers and a whole region and even a country could represent a single pollution source. Hence the plan to place a air-scrubbing building at the heart of the problem – an urban core.

Consistent with CC technology and the principle of photosynthesis, the Hyper Filter Skyscraper is designed to inhale carbon dioxide and other harmful gases and exhale concentrated oxygen. The skin of the project is made out of long pipe filters that ensure the cleaning process. While clean air is released to the atmosphere, all the harmful substances are stored for use in the chemical industry for later use. These can include chemicals products, biofuels, and even manufactured goods.

Hyper-speed Vertical Train Hub:
Verticle_train_skyscraper1All around the world, nations from the USA, UK, Japan and China are again consolidating futuristic proposals for an advanced public transport network, to maximize the economic growth of their cities. The Hyper Speed Vertical Train Hub is an extension of this, aiming to resolve the inevitable challenges that cities will face by 2075, and offering a deliverable and sustainable solution for the future of the transport generation.

As the world’s population dramatically increases, the demand for goods, natural resources, foods, fuel and land would have increased significantly by 2075. By then, the world’s population will reach an estimated 10 or 11 million, and the majority of them (6 or 7 billion) will gravitate towards living in mega-cities. This will increase pressure and competition for adjacent suburban land, therefore forcing cities to explore more innovative forms of public transport.

Verticle_train_skyscraperConsistent with a key principle of arcology, this proposal seeks to take advantage of vertical space in order to use available land more efficiently. By flipping the traditional form and function of the current train design into a vertical, cylindrical mass, the Vertical Train Hub seeks to eliminate the current impact that traditional stations have on land use, therefore returning the remaining site mass back to the densely packed urban Mega City.

This remaining land will surround the base of the tower forming a large urban park, leading towards to the base of the Hyper-Speed Vertical Hub. The trains will create a dynamic and kinetic facade, one that will be continuously evolving and responsive to the workings of the vertical hub. Passengers will travel into the main lobby, allowing travelers to ascend through the atrium and through the platforms and onto the carriages. The high-speed trains will maximize time efficiency, able to traverse 482 km (300 miles) in just thirty minutes.

As the train travels and transitions from its horizontal formation, and ascends up the facade vertically, the carriages will pivot similar to that on a ‘Ferris wheel’, allowing the passengers within the carriage to remain in an upright position and facing towards the cityscape. The carriages will be supported by a magnetic structure located at either side, eliminating the need for rails beneath, and allowing the carriages and its passengers to connect to the tower.

Launchspire:
launchspireDesigned by Henry Smith, Adam Woodward, Paul Attkins of theUnited Kingdom, the Launchspire is an arcological design that also seeks to eliminate much of the CO2 emissions associated with air travel. This year, commercial air travel is celebrating its centenary; and looking ahead to 2050, aviation is predicted to fly 16 billion passengers and 400 million tones of cargo. This radical re-interpretation of the skyscraper would eliminate the hydrocarbon dependency of aircraft during takeoff through the use of an electromagnetic vertical accelerator.

On short flights, as much as 25% of the total fuel consumed is used during takeoff. The most fuel-efficient route length for airlines is 4,300 kilometers, but roughly half the flights taking place in the developed world cover less than 500 kilometers. An electromagnetic vertical accelerator, utilizing the technological principles developed at CERN’s LHC and maglev train propulsion, would provide a method for commercial aircraft to be accelerated to cruising speed using renewable electrical energy sources from ground-based infrastructure.

launchspire1This new design methodology envisions a ‘spiral tube’ structure that would reinvigorate the ‘core and floor plate’ model of high-rise buildings. Schools, hospitals, commercial, and residential properties would be interspersed throughout the tower with approximately one third of all Plots to be public green spaces, nature reserves and farm land. Due to the scale of the building, different climates would be experienced, with various wildlife and crop species, whilst also being natural devices for internal climate control.

The concept is essentially a helical version of the classic urban grid environment. This has the benefits of extreme high density, elevated living, mass transportation to different levels, pedestrian and cycle travel locally to enable healthy living. Community interaction and a unique and varied sense of place is achieved to each area of the tower. As the building ages specific areas develop to support an organic and culturally rich network of settlements within the matrix of the structure.

The towers can be built close to renewable energy infrastructures; hydropower in the mountains, tidal and offshore wind nearer the coast. The city is the building, the surrounding environment will remain natural thus the urban realm becomes a vertical entity within the wilderness. The building is effectively a confluence of road, rail, air and space transportation, and takes advantage of vertical spacing to reduce the impact on the local environment.

New Tower of Babel:
babelDesigned by Petko Stoevski of Germany, this perhaps unfortunately-named building seeks to invert the relationship between structures and their surrounding environment. Essentially, it is a steel construction built over a desert surface with multiple levels planned depending on the landscape’s topology. The top two panels are made of glass, and the air contained in between is warmed up by the sunlight. The structure is slightly tilted upwards, which leads the air to the middle of the tower into an inner cylindrical.

The updraft power channels the warm air into the chimney tower, propelling the wind turbines located in the base and converting the kinetic energy into electrical power. Under the glass panels, photovoltaic panels are placed to generate electricity while reflecting the sunrays, thereby offering more warming. Moreover, the photovoltaic panels cast a shadow, cooling down the land’s surface and creating a microclimate that allows the creation of residential and recreational areas as well as the development of agriculture.

The Tower of Babel establishes a new landscape, which makes use of the natural forces of an upwind power plant and therefore stretches from the horizontal to the vertical. The building is characterized by many different spaces and leaves their use open to improvisation. Therefore, life develops in different places with different intensity. The project reinforces the principles of sustainability, which allow long term economic, social, and ecological development.

PleXus Tower:
PieXus_towerDesigned by Chris Thackrey, Steven Ma, Bao An Nguyen Phuoc, Christos Koukis, Matus Nedecky, Stefan Turcovsky of the United States, the PleXus Tower is proposed development for the West Hong Kong Harbor. It was conceived as a segmented, but highly connected network of major transportation functions, as well as housing conventional program, that would merge the concepts of interconnectedness, renewable energy, and ecology into the same fabric.

The design starts out as a series of distributed pods reaching out to connect with the city’s transportation, accepting traffic in the form of boats, ferries, and other water vehicles. Bridged together by connected pipelines over the water, these pods work in harmony with the existing Macau Ferry Terminal. As people move inward from these pods, they travel through a series of different structures, beginning with  a horizontal parking structure that also connects to the highway network to efficiently receive car traffic.

PieXus_tower1Farther up, business and shopping space is available, all accessible by car to the highest level of the tower. The upper reaches of the towers are set aside for residential space, providing a living area that incorporates spectacular views of the dynamic city skyline. A heliport on top that can receive air traffic from above, and power is supplied by the south-facing side of the building that comes equipped with numerous solar panels.

The skin is also breathable, with numerous openings designed to overlap each other, undulating throughout, allowing carbon dioxide to easily filter out from the designated parking areas on the lower levels. Each parking level will also utilize foliage to further filter carbon dioxide from the air helping to reduce pollution in Hong Kong. At night, lights will glow from the panels, reminding people of the connections these segments share as well as blending in with Hong Kong’s unique night skyline.

Project Blue:
project_blueDesigned by Yang Siqi, Zhan Beidi, Zhao Renbo, Zhang Tianshuo of China, Project Blue is designed with China’s explosive growth in mind. On the one hand, the country’s “economic miracle” has left the world in awe. But on the other, the country is paying a big price for being the “factory of the world”, in the form of getting polluted at an alarming speed. Chinese cities are now characterized by an unhealthy hazy weather as the result of large amounts of suspended particles in the air.

The purpose of Project Blue is to transform suspended particles into green energy by creating an enormous upside down cooling tower with a multi-tubular cyclic desulfurization system that produces nitrogen and sulfur. When both elements are combined with the atmospheres surplus of carbon monoxide, the result is “water coal” that would later be transformed into methane through a low-pressure reaction called low pressure efficient mathanation.

This methane could then be converted into biofuel that would then be shipped to the surface, providing a clean alternative for China’s fast-growing supply of gasoline cars. Consistent with many modern designs that utilize carbon capture technology, Project Blue would therefore be combating the problem of emissions and air pollution at both ends.

Rainforest Guardian:
3028400-inline-rainforest-guardian
While most of the concepts were designed for cities, a few were made for more remote locations. The Rainforest Guardian, from Chinese architects Jie Huang, Jin Wei, Qiaowan Tang, Yiwei Yu, and Zhe Hao, was one such example. Designed to sit on the edge of the Amazon, capturing and storing rainwater in the rainy season to help fight fires in the dry season, the building also has labs located at the top for scientists studying and monitoring the local environment.

The lotus-shaped water tower is captures rainwater directly and then filters and stores it in its spare reservoirs. Using capillarity combined with active energy, the aerial roots with a distinct sponge-structure can absorb and store the excess water without disturbing the Amazon’s ecosystem. In the case of fire, firefighters fly to the scene and extinguish the fire with the collected water. In addition, the laboratories can act as exhibition spaces for tourists to create environmental awareness.

Sand Babel:
0656-1Produced by designers Qiu Song, Kang Pengfei, Bai Ying, Ren Nuoya, and Guo Shen of China, the Sand Babel uses an idea similar to that being proposed by NASA and the ESA to build settlements on the Moon. Basically, their plan is to use sintering and additive manufacturing to turn desert sand into a series of ecological skyscrapers.These structures would serve as scientific research and testing facilities, tourist attractions for the desert, and would be divided into two parts.

The first part, located above ground, consists of several independent structures for a desert community while the second part, located partially underground, would connect several different buildings together and create a multi-functional tube network system. The main portion of each building is constructed with sand, sintered through a solar-powered 3D printer to create walls of solid ceramic.

The top structures utilizes a spiral skeleton shape, inspired by desert phenomena like Tornadoes and mushroom rocks. These are tall, straight and have high tensile strength, and are thus able to withstand high winds. The net structure of the lower sections are similar to tree roots, effectively anchoring each building into the ground. The dual funnel model provides cooling through cross-ventilation, as well as ensuring that water can be collected through condensation.

Seawer:
seawerDesigned by Sung Jin Cho of South Korea, the Seawer was inspired by another major environmental issue – the problem of waste. Every year, millions of tons of trash enter the ocean, and between 60 and 80 percent of it is from land-based sources. Due to ocean currents, this waste collects in particular areas of the world, such as the one currently located in the North Pacific Subtropical Gyre. Consisting of tiny particles of plastics, this area is commonly referred as the Great Pacific Garbage Patch (GPGP), or just “Garbage Island”.

The GPGP is twice the size of Texas and contains six times more plastic than plankton biomass. And since plastic is not biodegrade, it poses a threat to thousands of marine animals. Seawer proposes to install a huge drainage hole 550 meters in diameter and 300 meters in depth in the middle of the GPGP that would engulf all kinds of floating trash filled with seawater. Seawer consists of five layers of baleen filters, which separate particles and fluids and collected the particles together.

seawer1These collected plastics are then taken to a recycling plant atop of the structure while seawater is filtered and stored in a large sedimentation tank at the bottom to be further cleaned and released into the ocean. Much like skyscrapers that are energy-independent and turn air pollution into useable fuels, the Seawer concept is all about making a future city that can offer solutions, and placing it at the heart of the problem.

Skyvillage:
skyvillageDesigned by Ziwei Song of the United States, the Skyvillage concept was inspired by Los Angeles’s freeway system, which he claims segregates the city’s fabric and restricts urban activities to single locations. As a result, Song envisioned a vertical city that would encourage urban integration by providing a bridge over freeway interruptions and connect the four quadrants around the 101 and 110 freeways. This single architectural organism would also boost cultural exchanges, urban activities, and social interaction.

The interchange 101 and 110 breaks Los Angeles east urban fabric into four disconnected quadrants: Downtown, Chinatown, Echo Park, and Temple Beaudry. The four quadrants have distinct cultural and social differences, lacking a coherent urban tissue. Moreover, the leftover space around the freeways reaches over 27 acres. Skyvillage aims to reclaim this vague terrain and provide green filtering towers to clean the freeways and also articulate various programs to revitalize the disconnected urban fabric.

Urban Alloy Structure:
urban_alloyLast, but certainly not least, there is the design concept that was put forth this year by Matt Bowles and Chad Kellogg of the United States. Known as Urban Alloy, the concept was inspired by cities like New York and other dynamic cities of the 21st century – which they refer to as “anthropomorphic alloys”. In short, these cities act as engines for innovation and social cohesion which, combined with their continually evolving demographics, will forge the dynamic societies of the future.

Once again, the concept calls for smart growth – developments that promote innovation and renewal without disrupting current land use. Hence their proposal for a residential typology that surrounds the intersection of transportation hubs – such as elevated train lines and freeway interchanges – with a set of highly linked living environments that capture the air rights above these systems. The design and skin of the structure also reflects a blend of space types and a desire to optimized shading and day lighting.

urban_alloy2Composed of a series of different alloys and composites, the system is deployed on a grid that follows the geometric pattern of the surface. This grid is designed for integration with adjoining pieces of the structure, and to optimize shading and lighting so the building doesn’t cast a huge shadow over adjacent areas (which is a common problem for skyscrapers). The resulting architecture is a steel diagrid system that can efficiently be constructed with each unique member cut by an automated system (i.e. 3D metal printing)

The relatively light weight of each structural unit also means that it can be constructed with greater ease, cutting down on construction costs and the carbon foot involved. The wall systems are also built with a high content of recycled materials, making it a comparatively eco-friendly structure compared to most modern skyscrapers.

Summary:
An impressive collection, isn’t it? And this is not even the complete list of winners and runner-ups, just those that I felt I could squeeze in to this here humble post. Alas, it gives a pretty good idea what the great minds of the world are coming up with when they consider the needs of urban residents and cityscapes in the coming years and decades. In addition to providing housing, energy, transportation and basic services in ways that are sustainable, top marks go to those who can turn problems into solutions.

When Paolo Soleri first conceived of his Arcology concept, he was looking for a way to provide room for more people with less space, and in a way that did not further tax the environment. However, since the 1970’s, this challenge has been updated thanks to the advance of Climate Change. At this juncture, simply not adding to the problem is no longer sufficient. Future living solutions must also find ways to reduce and roll back the damage.

Hence concepts that now call for carbon capture, garbage processing, and pollution control in addition to the smart use of space, urban agriculture, and renewable energy. It is one of the paradoxes of the modern age that cities are both the cause, and solution to, the problems of modern living. While they may bring millions of people together in one place, producing tons of waste and pollution, they also bring together ideas for change and innovation that lead to better living.

In the end, ideas that expand upon this paradox – turning cities into pollution and garbage-eating factories – will not only determine the size and shape of future cities, they may very well ensure the survival of the natural environment and the human race itself. Much like all life on this planet, we remain permanently connected to space and place and are dependent on it for our livelihood and our very lives. The only way to keep living in to learn to live with it.

The Glucose Economy

hacking-bacteria-fuel-ecoli-670In the long search to find alternatives to fossil fuels and industrial processes that produce tons of waste, several ideas have been forward. These include alternative energy – ranging from solar, wind, geothermal, and tidal – additive manufacturing, and cleaner burning fuels. All of these ideas have begun to bear some serious fruit in recent years thanks to ongoing research and development. But looking to the long term, it is clear that a complete overhaul of our industrial economy is needed.

That’s where more ambitious ideas come to the fore, ideas like nanotechnology, biotechnology, and what’s known as the “Glucose Economy”. Coined by Steven Chu, a Nobel Prize-winning Chinese-American physicist who also had the honor of serving as the 12th Secretary of Energy under Barack Obama, this concept calls for the development of an economic model that would replace oil with high-glucose alternative fuels.

110302_steven_chu_ap_328Chu conceived of the idea while working as a professor of physics and molecular and cellular biology at the University of California, Berkeley. In short, the plan calls for fast-growing crops to be planted in the tropics – where sunlight is abundant – converted into glucose (of which cellulose, which makes up much of the dry weight of a plant, is a polymer). The resulting glucose and cellulose would then be shipped around much as oil is today, for eventual conversion into biofuels and bioplastics.

As expected, this would render the current system of converting oil into gasoline and plastics – a process which produces immense amounts of carbon dioxide through processing and burning – obsolete. By comparison, glucose fuels would burn clean and produce very little in the way of chemical by-products, and bioplastics would be far more resilient and eco-friendly than regular plastics, and not just because they won’t cause a terrible disposal and waste problem (see Garbage Island).

David-Benjamin-and-the-future-of-architecture-01Another benefit of the this new model is the economic development it will bring to the tropical regions of the world. As far as production is concerned, those regions that stand to benefit the most are Sub-Saharan Africa, Central and South America, and South-East Asia. These regions are already seeing significant economic growth, and a shift like this would ensure their continued growth and development (not to mention improved quality of life) for many generations  to come.

But above and beyond all that is the revolutionary potential that exists for design and manufacturing, with architects relying on specially-designed software to create multi-material objects fashioned in part from biomass. This unique combination of biological processes, computer-assisted design (CAD), and human intelligence is looking to trigger a revolution in manufacturing and construction, with everyday materials to buildings created from eco-friendly, structurally sound, biomaterials.

bio-buildingOne such architect is David Benjamin, a computational architect and principal of the New York-based practice The Living. Together with his collaborators, Benjamin is conducting experiments with plant cells, the latest of which is the production of xylem cells – long hollow tubes plants use to transport water. These are computer modeled and grown in a Cambridge University lab and studied to create materials that combine the desired properties of different types of bacteria.

In addition, they are working with sheets of calcium and cellulose, seeking to create structures that will be strong, flexible, and filigreed. And beyond The Living Thing, there are also initiatives like the Living Foundries Program, a Department of Defense initiative that is hoping to hasten the developmental process and create an emergent bio-industry that would create “on-demand” production.

1394231762-re-making-manufacturing-united-statesNot only would this shave decades off the development process, but also hundreds of millions of dollars. What’s more, Benjamin claims it could take only 8 to 10 years to see this type of biotechnology enter commercial production. Naturally, there are those who oppose the development of a “glucose economy” as advocated by Chu. Beyond the proponents of fossil fuel energy, there are also those advocate nationally self-sufficient resources bases, rather than foreign dependence.

To these critics, the aim of a future economy should be energy independence. In their view, the glucose economy is flawed in that it merely shifts energy dependence of nations like the US from the Middle East and OPEC to the tropics, which could create a whole new slew of geopolitical problems. However, one cannot deny that as alternatives go, Chu’s proposal is far preferable to the current post-peak oil model of frakking, tar sands, natural gas, and coal.

bio-building1And it also offers some new and exciting possibilities for the future, where building processes like additive manufacturing (which is already making inroads into the construction industry with anti-gravity 3D printing, and the KamerMaker House) would be supplemented by using “biohacked” bacteria to grow structures. These structures would in turn be composed of resilient materials such as cellulose and organic minerals, or possibly carbon nanotubes that are assembled by organic processes.

And the amount of money, waste, energy and lives saved would be immense, as construction is currently one of the most dangerous and inefficient industries on the planet. In terms of on the job accidents, it causes some 10,000 deaths and 400,000 injuries a year in the US alone. And in terms of resource allocation and money, construction is labor intensive, produces tons of waste, and is almost always over budget.

hacking-bacteria-bio-light-670Compared to all that, a system the utilizes environmentally-friendly molecules and materials, enhances growing operations, fostered greater development and economic cooperation, and leads to a safer, cheaper, less wasteful construction industry seems immensely preferable. And it does offer a solution of what to do about two major industries that are ailing and in desperate need of modernization.

Boy, it feels like a long time since i’ve done a conceptual post, and the topics do appear to be getting more and more serious. Can anyone recall when I used to do posts about Cool Ships and Cool Guns? Yeah, me too, vaguely. Somehow, stuff like that seems like a far cry from the Internet of Things, Interstellar Travel, O’Neill Cylinders, Space Elevators, and timelines of the future. I guess this little blog of mine has been growing up in recent years, huh?

Stay tuned for more conceptual posts, hopefully something a little lighter and fluffier next time 😉

Powered by the Sun: Mirrored Solar Dishes

sun_magneticfieldIn the race to develop alternative energy sources, solar power is the undeniable top contender. In addition to being infinitely renewable So much sunlight hits the Earth each day that the world’s entire electricity needs could be met by harvesting only 2% of the solar energy in the Sahara Desert. Of course, this goal has remained elusive due to the problem of costs – both in the manufacture of solar panels and the installation therefor.

But researchers at IBM think they’re one step closer to making solar universally accessible with a low-cost system that can concentrate the sunlight by 2,000 times. The system uses a dish covered in mirrors to aim sunlight in a small area, and which follows the sun throughout the day to catch the most light. Other concentrated solar power systems do the same thing, but a typical system only converts around 20% of the incoming light to usable energy, while this one can convert 80%.

Inline_solardishThis not only ensures a much larger yield, but also makes the energy it harvests cheap. Bruno Michel, the manager for advanced thermal packaging at IBM Research, believes the design could be three-times cheaper than “comparable” systems. Officially, the estimate he provides claim that the cost per kilowatt hour will work out to less than 10 cents, which works out to 0.01 cents per watt (significantly cheaper than the $0.74 per watt of standard solar).

But as he explains, using simple materials also helps:

The reflective material we use for the mirror facets are similar to that of potato chip bags. The reinforced concrete is also similar to what is being used to build bridges around the world. So outside of the receiver, which contains the photovoltaic chips, we are using standard materials.

A few small high-tech parts will be built in Switzerland (where the prototype is currently being produced). but the main parts of the equipment could easily be built locally, wherever it’s being used. It’s especially well-suited for sunny areas that happen to be dry. As the system runs, it can use excess heat that would normally be wasted to desalinate water. Hence, a large installation could provide not only abundant electricity, but clean drinking water for an entire town.

inline-i-solar-02A combined system of this kind could be an incredible boon to economies in parts of the world that are surrounded by deserts, such as North Africa or Mongolia. But given the increasing risk of worldwide droughts caused by Climate Change, it may also become a necessity in the developed world. Here, such dishes could not only provide clean energy that would reduce our carbon footprint, but also process water for agricultural use, thus combating the problem on two fronts.

IBM researchers are currently working with partners at Airlight Energy, ETH-Zurich, and Interstate University of Applied Sciences Buchs NTB to finish building a large prototype, which they anticipate will be ready by the end of this summer. After testing, they hope to start production at scale within 18 months. Combined with many, many other plans to make panels cheaper and more effective, we can expect to be seeing countless options for solar appearing in the near future.

And if recent years are any indication, we can expect solar usage to double before the year is out.

Ann Makosinski and I Have a Chat!

Ann-Makosinski-Google-Science-Fair-2It’s a rare thing when a humble blogger like yours truly gets the chance to speak to someone who has truly made a difference in the world. And this time around, that person is Ann Makosinki, inventor of the body heat-powered flashlight and winner of last year’s Google Science Fair. In addition to being a young inventor, she also happens to hail from my neck of the woods here in Victoria, British Columbia. So you can imagine the enthusiasm I felt when she agreed to this interview!

As many of you may already know  – since you all faithfully read this blog 😉 – Ann Makosinki is winner of the 2013 Google Science Fair Award for her invention that uses the warmth of a person’s own hand to power an LED flashlight. Using Peltier tiles, which produce electricity when heated on one side and cooled on the other, she developed a flashlight which she believes will be of use in the developing world where electrical outlets and batteries are not always available.

body_heat_flashlightAnn’s inspiration comes from her commitment to science, renewable energy, the environment, and her roots in the Philippines. Ultimately, her goal is to bring light and energy to those who live without it all over the world. After winning the gold medal at the 2013 Canada-Wide Science Fair Gold Medal, her flashlight won at the Google Science Fair’s top prize of a $25,000 scholarship and the choice of a “once-in-a-lifetime experience” from CERN, LEGO or Google.

In addition, she has been a keynote speaker at TEDx in three different cities (Vancouver, Redmond and Edmonton), at Techtoria here in Victoria, earned a spot on Jimmy Fallon Live, and will be representing Canada at the 2014 International Science and Engineering Fair this coming May. The following is a transcript of our interview, which occurred via email in spite of her (very) busy schedule:

1. When did you first discover your love for science? What are some of your earliest memories of doing something science-related?

My love for science started when I was very young. My first toy was actually a box of transistors! I was always also interested in insects, and used to collect them and keep them in jars. I would feed them and spray them each morning before I would head out to school. My parents were very supportive of my interests, even if I was looking through the garbage, hot gluing disposed objects together and creating “inventions” (of course nothing ever worked). My dad also always took me to the local island science fair, and I was very shy to ask the other kids questions, but I always thought it was so cool that they had chosen their own topic in science and now were presenting on it.

2. When did you take part in your first science fair? What was your project?

I started participating in the local science fair, the Vancouver Island Regional Science Fair, when I was in grade 6. My science project was one from that I had done in class, comparing two laundry detergents.

3. How did you come to be interested in renewable energy?

I realized early on that energy is a key issue in today’s world, because of our increased reliance on energy and its effect on global warming. It is a challenging problem, and I wished to explore alternative energy sources and find solutions. I focused on the problem of battery elimination, because that’s something I understand and can think around.

4. You’re invention of the body-heat powered flashlight was a big hit at the 2013 Google Science Fair. What was it like competing with people your age who have such a passion for science?

For me, it wasn’t about competing with the other people, but more of getting know them and seeing how we were all alike in some ways. It inspired me to see how passionate they were about science, and while we could have conversations about technical aspects that I usually wouldn’t get to talk about with my friends, they were all still like normal teenagers.

5. This past December you were named one of Time Magazines Top 30 under 30. What other accolades have you earned since winning at the Google Fair?

Hmm, well I have given three TEDx talks since then and many other speeches locally. I have had numerous interviews/film crew from US and Europe making short documentaries. I also appeared on the Tonight Show with Jimmy Fallon’s during the show’s premiere week, and I have a few more things lined up. However, I think what matters most to me is the fact that my project has brought so much awareness to the problem of people without electricity, and to the potential that thermoelectricity has.

6. Since winning at Google Fair, you’ve presented at TEDx RenfrewCollingwood, the Techtoria conference in Victoria, and got a spot on Jimmy Fallon Live. Is it fair to say your life has changed since debuting your invention? Do you feel like a celebrity?

I definitely do not feel like a celebrity. Sure, I get recognized once in a blue moon, or people want to have their picture with me, but I know that will soon end. I think something that has changed is the fact that I really value the time when I can wind down and relax, because with so much going on I’m always on the go and worrying about my next due date.

7. What is the future hold for renewable energy, in your opinion?

I think we are already seeing a huge increase in the interest in renewable energy and alternative energy sources. As global warming and the greenhouse effect closes in on us, we will be obliged to look around to harvest natural energy, whether it be from heat, sun, water, wind etc. It holds a lot of potential, but our technologies for harvesting the energy efficiently are still developing. If my flashlight can eliminate even a fraction of batteries from the city dumps, I will have achieved my aim.

8. What does the future hold for Ann Makosinki?

I hope to commercialize the flashlight and make it available to children in the world who need light the most. Beyond that, I hope to get into college and make my little contribution towards a cleaner and better world to come.

She hopes to commercialize the flashlight? I for one can’t believe that she hasn’t been approached by every company from GE to Applied Solar. But it is great to know that young minds are coming up with breakthroughs that could be making a very real difference in the world of tomorrow. I, for one, consider to be right up there with the Darfur Stove and Quetsol solar-powered lights.

And be sure to check out the video of Ann’s speech at TEDx RenfewCollingwood which took place in October 2013, entitled “Be the Source”:


And here is her guest spot on Jimmy Fallon Live, as part of GE’s “Fallonventions”, from this past February:

Drone Wars: Protecting Endangered Animals

WWF_droneDespite anxieties associated with drone use – most of which have to do with domestic surveillance and warfare – there are numerous positive uses for the technology. Whether it is keeping an eye on oil rigs, monitoring underground cables, spying on drug or human traffickers, or ecological surveillance, there are plenty of uses for unmanned aerial vehicles beyond warfare and invading privacy.

In Namibia, for example, where poaching remains a problem, drones may be the key to protecting the endangered rhino and elephants. Namibia’s Ministry of Environment and Tourism, along with the World Wildlife Fund and funding from Google, have partnered to invest in drones that can track rhino and elephant herds. Through the use of these drones, the researchers were able to follow herds and alert law enforcement in the event the animals were being targeted by poachers.

WWF_drone_graphicIn field tests conducted in two national parks in November 2013, drones with 2-metre wingspans flew day and night missions to video black rhino herds and send live footage to poacher-tracking rangers on the ground. Smart radio tags attached to rhinos allowed the drones to home in on each herd’s current location. Crawford Allan, leader of the Wildlife Crime Technology Project at WWF, put it as follows:

We broke new ground using technologies that have never been integrated before to provide powerful wildlife protection.

The MET says it will now press ahead and deploy drones in areas of Namibia where rhinos and elephants roam. WWF estimates that illegal poaching in Africa nets criminals $10 billion each year – with some 22,000 elephants killed annually and 1000 rhinos killed last year in South Africa alone. Their efforts are also thinning out elephant and rhino populations and putting the entire ecosystem at risk.

conservation_rhinoAlthough the drone program should help prevent poaching in Namibia, the issue is widespread across Africa. It’s not clear whether a similar program will be rolled out elsewhere, but any success incurred in Namibia to stop poaching will set a precedent others are sure to follow. And, it should be noted, this country and the WWF are hardly alone in wanting to adapt UAV technology to the goal or ecological or species conservation.

In many ways, MET’s use of high-tech to protect wildlife echoes that of Technology For Nature (TfN), a joint venture of Microsoft Research in Cambridge, UK, University College London and the Zoological Society of London. Led by Lucas Joppa and Siamak Tavakoli at Microsoft, TfN is getting similar drone and animal-tagging projects off the ground in the Republic of the Congo, the Seychelles and Zambia.

conservation_drones_inlineAnd then there’s Conservation Drones, a non-profit organization co-founded by Serge Wich – a professor in primate biology at John Moores University. Made up of researchers and technologists, the group’s mandate is to spread drone use around the world for the sake of conservation. So far, they have worked with conservation groups and governments in Nepal, Indonesia, Gabon, and Greenland, and Wich hopes to visit more countries later this year.

According to Wich, the challenges to conservation go beyond simply monitoring endangered animals, which may be in too few number to accurately keep track of. There’s also the matter of the rough and vast terrain, which can be very difficult to physically cover. Drones are a big game changer in this game. By covering large areas in surveys, doing it repeatedly, and automating some of the analysis, aerial vehicles can track wildlife in a more comprehensive and efficient way.

conservation_dronesThanks to the growth of commercial aerial drones in recent years and the significant reduction in price, the technology is becoming much more affordable and user-friendly. The kits Conservation Drones uses cost no more than about $3,000, and the latest version has an open-source autopilot platform from California, along with a GPS tracker and altimeter. It’s then fitted with still cameras or video. As Wich himself put it:

The potential is huge to allow people to do very efficient data collection on a variety of issues that are important for conservation. We often struggle determining how many animals there are, where human encroachment is occurring. There are an enormous amount of ecological questions we can address with these systems.

To set a flight path, Wich simply plugs in a few points on a Google Map, then launches the drone by hand. The battery-powered module can fly for up to an hour, and cover a maximum distance of about 40 km (25 miles). The drones offer an aerial view, allowing Wich and his colleagues to get a close-up view unobscured by clouds. The next step is to improve the analysis of the images that come back.

conservation_drone_mosaicConservation Drones is now working to automate the counting process, and build up picture-maps by stitching hundreds of images together (like the one above). It also wants to create 3-D model environments, providing a sort of living inventory of what’s been destroyed and what remains. Long-term, it is hoped that governments all over the world with conservation problems will used the detailed software and aerial drones to keep tabs on their endangered animals and habitats to ensure their protection.

Several other groups are also pioneering drones-for-conservation, notably the World Wildlife Fund working with Google, the International Anti-Poaching Foundation, led by Iraq War veteran Damien Mander, and ShadowView, a group out of the Netherlands. Poachers beware. In addition, the Zambian Carnivore Program will be testing a pair of VHF-radio-equipped quadcopter drones in the US soon and he hopes to begin testing the miniature aircraft in Kafue National Park in Zambia in May.

In the meantime, check out this video of the MET/WWF drone survey:

The Future of Transit: The Solar-Powered Jetliner

skywhale1Solar-powered airplanes have already proven feasible, but only in the sense of single-seat, turboprop powered plane.s When it comes to a long-range, commercial jet aircraft, the field remains pretty sparse so far. But thanks to a Spanish designer, and some unconventional thinking, “whale planes” that are eco-friendly and combine the convenience of air travel with the luxury of a cruise ship might soon be a reality.

Oscar Viñals, from Barcelona, envisioned the “AWWA Sky Whale” concept plane as a mixture of today’s current designs and future concepts that don’t yet exist. The end result is like an Airbus A380, but with considerable expansion and designed to be powered by micro solar panels and four large hybrid electric engines that would rotate to ease takeoff and landing.

skywhale_specsIn addition to reducing noise and pollutants, it would also significantly reduce fuel burned during what is currently one of the least green modes of getting to a destination. Despite the introduction of more fuel-efficient and less polluting turbofan and turboprop engines, the rapid growth of air travel in recent years has contributed to increasing CO2 emissions in the upper atmosphere.

In fact, in the European Union alone, greenhouse gas emissions from aviation increased by a total of 87% between 1990 and 2006. In 2005, global aviation contributed roughly 5% to the overall “radiative forcing” effect that our annual emissions of CO2 have on Global Warning, but the added effects of water vapor and the disruption to cirrus cloud formations also enhances this role to a varying degree.

skywhale4One of the reasons aviation’s role in Climate Change is overlooked is because the focus tends to be on urban infrastructure and automobiles, which account for the vast majority of carbon emissions. But given the current trend of increasing travel, international economic development, and growth in tourist industries, aviation is likely to get a bigger slice of that pie down the road and clearer methods need to be devised.

Hence the concept for the Sky Whale, which Viñals imagines would come with other futuristic components . These include a self-healing skin with adaptable opacity, active wings that change shape as needed, and ceramic and fiber composite materials. He even has a plan for the plane to break apart on an emergency landing, with the wings separating from the fuselage to limit damage to the passenger compartment.

skywhale3The three-story aircraft, which could accomodate 755 passengers, would have a wingspan and height greater than any of today’s biggest carriers – 88 meters in comparison to the 80 meters on an Airbus A380-900 – making it the largest commercial aircraft in existence. However, the combination of active wings (which would also reduce drag) and the hybrid-electric systems would render it the most fuel efficient.

Another thing that Viñals imagines would make it into the design is virtual reality windows – aka. display glass that allows people to go online, watch movies, and experience in-flight entertainment simply by looking outside. Can’t imagine why this would be necessary, as the range of personal devices people are likely to have by this time ought to be entertainment enough. And failing that, the view should be enough to inspire!

skywhale5Naturally, much of this technology – particularly the healing smartskin – is still many years away. But judging by the reaction to his designs, there is definitely some hunger for innovation in how we fly. Given the range of ideas for mass transit (like the Hyperloop, podcars, etc.) and personal transit (robot cars, robotaxis), it’s only a matter of time before the way we fly becomes smarter, sleeker, and cleaner.

The Future of Energy: Cold Fusion for US and China

NASA_coldfusionThe science behind cold fusion has been a source of constant controversy for decades. Not only has this pursuit turned up its share of phony claims, the fact that it also promises to yield clean, abundant energy on the cheap has led to no shortage of romantic endorsements and vocal detractors. But if it could be made to work, there is no doubt that our energy problems would be solved, and in a way that is not harmful to our environment.

Last February, NASA made waves by announcing that they were working towards cold fusion through low-energy nuclear reaction (LENR) technology. Then in September, the National Ignition Facility (NIF) in California announced a major milestone when they managed to produce a controlled reaction that provided more energy that was required to start it.

e-cat1But all of that seemed to pale in comparison to the announcement by Andrea Rossi’s that he managed to create a fusion power plant that was reportedly capable of generated a single megawatt of power. Known as the E-Cat 1MW Plant (short for Energy-Catalyser), Rossi announced its creation back in November, and indicated that he and his company were taking pre-orders and that they would start deliveries by 2014.

Today, the big news is that a large US investment company has acquired the rights to the cold fusion LENR technology. That investment company is Cherokee Investment Partners, and they appear to be interested in deploying the cold fusion tech commercially in both China and the US to meet both countries existing and projected energy needs.

fusion_energyRelying on the same process as other LENR technology, the E-Cat generates cold fusion by taking nickel and hydrogen and fusing them into copper – a process that has 10,000 times the energy density of gasoline, and 1,000 times the power density. Rossi says he’s found a special catalyst that makes the process work, but many scientists remain unconvinced.

Regardless of whether or it not it can deliver, it now seems that Rossi’s previously allusions to an American partner are true after all. Much like everything surrounding Rossi, he chose to be nebulous about the identity of the company that was supporting him. However, with this latest deal, Cherokee and its CEO Thomas Darden, a man who has a history of investing in clean energy, is a believer in the design.

e-cat3In addition to preparing the patents through a Limited Liability Company – known as Industrial Heat – there are also reports that Darden recently visited China to showcase the E-Cat to Chinese officials and businesspeople. China is reportedly looking at using the E-Cat to significantly reduce its carbon footprint and meet its the energy needs of its growing cities in a way that won’t generate more air pollution.

Needless to say, this deal has bolstered Rossi’s and the E-Cat’s credibility, but the technology remains unproven. Rossi says that he has a team of international scientists that are planning to do another round of tests on the E-Cat which are slated to end in March, with a peer-reviewed report to follow sometime after that. Fingers crossed, those rounds of test will provide conclusive proof.

Then, we can all get to work dreaming about a bright, clean future, and the thousands of applications such plants will have!

Climate Crisis: Where are the Bees Going?

bee_pollen_macroOne of the greatest threats to our planetary ecosystem is the threat of bees going extinct, a phenomenon that is often filed under the heading of Colony Collapse Disorder (CCD). Because of their role in pollination, bees are an integral part of the environment, and their disappearance would mean the sudden collapse of all life on the planet in just a few years time.

Because of this, environmentalists and entomologists are looking for ways to address the disappearance of bees. One solution, as put forward by a team of Australian scientists working in Tasmania, is to outfit bees with tiny microchip trackers to monitor their movements. By turning them into an army of mobile data-collectors, the team hopes to determine why the local bees are abandoning their hives.

bee_chipsFor the past five months, this team has been capturing hundreds of bees, refrigerating them, shaving them, and gluing tiny sensors – which weigh about 1/4000th of a paperclip – to their backs. So far, the team has captured, tagged and released hundred bees, but the team plans to engineer a total of 5000 with these chips for the sake of their research.

Dr. Paulo de Souza, the lead scientist on the project, explained the capture and tagging process as follows:

The bees are very sensitive to temperature. We take the bees to the lab in a cage, we put them in a fridge with temps around 5 degrees Celsius, and in five minutes, all the bees fall asleep, because their metabolism goes down. We rub a bit of glue on them, and then attach the sensor. We carry them back, and in five minutes the bees wake up again.

colony_collapse_disorderBy monitoring their behavior, the scientists are trying to prevent Colony Collapse Disorder, the mysterious phenomenon in which worker bees suddenly abandon their hives. As it stands, no one is entirely sure what causes CCD, but  biological diversity, diet, management of the hives, radiation, and pesticide use are all possible influences on the bees’ behavior.

Colony Collapse Disorder remains a mystery that not only effects bees, but entire industries. If bees don’t pollinate fruit crops well enough, production decreases, prices rise, and local ecosystems can collapse. Tasmania, who’s huge agricultural tracts accounts for 65% of all Australian crop exports, could be devastated. Hence why de Souza and his colleagues are using it as a testing ground for their research.

bee_chips1In addition to monitoring the bees movements and checking in with them via RFID readers installed near hives and feeding stations, they’ve also created an experiment which exposes some bees to environmental contaminants (like pesticides) where other hives remain pesticide-free. By examining the effect on bees’ movements, they’ll be able to determine which factors cause bee disorientation and abnormal behavior.

As DeSouza explains it, the tagging and tracking process works a lot like a swipe card:

When you go to your office, you swipe a card to gain access. We assign different numbers to the devices on the bees, so we have 5,000 of these micro-sensors with one specific number. We follow not only the swarm, but each of the individuals to see what they’re doing.

colony_collapse_disorder1The scientists will also be able to examine bee data through several generations within the hive. When the contaminated pollen turns to nectar, other bees within the hive feed on it, and pass contamination on to their offspring. To de Souza’s knowledge, this is the first time scientists have attempted to measure hive contamination on this scale.

Right now, their main goal is to understand CCD before it reaches Australia’s shores and effects its agricultural operations. But the research is expected to have far-reaching implications, helping to address a major ecological concern that effects the entire world. And in the long run, de Souza and his team are looking to refine the process and take it even further.

HoneyBeesOnYellowFlowersThis includes adding more features to the chips and applying them to other species of crucial and threatened insects. Key to this, says de Souza, is miniaturization:

As the chips go down in size, we’ll also be able to use this in other insects. Fruit flies, for example, are another insect incredibly important for biosecurity in Australia.

An interesting concept, isn’t it? Big data meets entomology meets ecology, and all for the sake of preserving a crucial part of the food industry and an integral part of our environment. Because ultimately, its not just about preventing colonies from collapsing, but the Earth’s ecosystems as well.

Powered by the Sun: Efficiency Records and Future Trends

solar_panelThere have been many new developments in the field of solar technology lately, thanks to new waves of innovation and the ongoing drive to make the technology cheaper and more efficient. At the current rate of growth, solar power is predicted to become cheaper than natural gas by 2025. And with that, so many opportunities for clean energy and clean living will become available.

Though there are many contributing factors to this trend, much of the progress made of late is thanks to the discovery of graphene. This miracle material – which is ultra-thin, strong and light – has the ability to act as a super capacitor, battery, and an amazing superconductor. And its use in the manufacture of solar panels is leading to record breaking efficiency.

graphene-solarBack in 2012, researchers from the University of Florida reported a record efficiency of 8.6 percent for a prototype solar cell consisting of a wafer of silicon coated with a layer of graphene doped with trifluoromethanesulfonyl-amide (TFSA). And now, another team is claiming a new record efficiency of 15.6 percent for a graphene-based solar cell by ditching the silicon all together.

And while 15.6 efficiency might still lag behind certain designs of conventional solar cells (for instance, the Boeing Spectrolabs mass-production design of 2010 achieved upwards of 40 percent), this represents a exponential increase for graphene cells. The reason why it is favored in the production of cells is the fact that compared to silicon, it is far cheaper to produce.

solar_power2Despite the improvements made in manufacturing and installation, silicon is still expensive to process into cells. This new prototype, created by researchers from the Group of Photovoltaic and Optoelectronic Devices (DFO) – located at Spain’s Universitat Jaume I Castelló and the University of Oxford – uses a combination of titanium oxide and graphene as a charge collector and perovskite to absorb sunlight.

As well as the impressive solar efficiency, the team says the device is manufactured at low temperatures, with the several layers that go into making it being processed at under 150° C (302° F) using a solution-based deposition technique. This not only means lower potential production costs, but also makes it possible for the technology to be used on flexible plastics.

twin-creeks-hyperion-wafer-ii-flexibleWhat this means is a drop in costs all around, from production to installation, and the means to adapt the panel design to more surfaces. And considering the rate at which efficiency is being increased, it would not be rash to anticipate a range of graphene-based solar panels hitting the market in the near future – ones that can give conventional cells a run for their money!

However, another major stumbling block with solar power is weather, since it requires clear skies to be effective. For some time, the idea of getting the arrays into space has been proposed as a solution, which may finally be possible thanks to recent drops in the associated costs. In most cases, this consists or orbital arrays, but as noted late last year, there are more ambitious plans as well.

lunaring-3Take the Japanese company Shimizu and it’s proposed “Luna Ring” as an example. As noted earlier this month, Shimizu has proposed creating a solar array some 400 km (250 miles) wide and 11,000 km (6,800 miles) long that would beam solar energy directly to Earth. Being located on the Moon and wrapped around its entirety, this array would be able to take advantage of perennial exposure to sunlight.

Cables underneath the ring would gather power and transfer it to stations that facing Earth, which would then beam the energy our way using microwaves and lasers. Shimizu believes the scheme, which it showed off at a recent exhibition in Japan, would virtually solve our energy crisis, so we never have to think about fossil fuels again.

lunaring-2They predict that the entire array could be built and operational by 2035. Is that too soon to hope for planetary energy independence? And given the progress being made by companies like SpaceX and NASA in bringing the costs of getting into space down, and the way the Moon is factoring into multiple space agencies plans for the coming decades, I would anticipate that such a project is truly feasible, if still speculative.

Combined with increases being made in the fields of wind turbines, tidal harnesses, and other renewable energy sources – i.e. geothermal and piezoelectric – the future of clean energy, clear skies and clean living can’t get here soon enough! And be sure to check out this video of the Luna Ring, courtesy of the Shimizu corporation:
