The Amplituhedron: Quantum Physics Decoded

amplutihedron_spanScientists recently made a major breakthrough that may completely alter our perceptions of quantum physics, and the nature of the universe itself. After many decades of trying to reformulate quantum field theory, scientists at Harvard University discovered of a jewel-like geometric object that they believe will not only simplify quantum science, but even challenge the notion that space and time are fundamental components of reality.

This jewel has been named the “amplituhedron”, and it is radically simplifying how physicists calculate particle interactions. Previously, these Interactions were calculated using quantum field theory – mathematical formulas that were thousands of terms long. Now, these interactions can be described by computing the volume of the corresponding amplituhedron, which yields an equivalent one-term expression.

theory_of_everythingJacob Bourjaily, a theoretical physicist at Harvard University and one of the researchers who developed the new idea, has this to say about the discovery:

The degree of efficiency is mind-boggling. You can easily do, on paper, computations that were infeasible even with a computer before.

This is exciting news, in part because it could help facilitate the search for a Grand Unifying Theory (aka. Theory of Everything) that manages to unify all the fundamental forces of the universe. These forces are electromagnetism, weak nuclear forces, strong nuclear forces, and gravity. Thus far, attempts at resolving these forces have run into infinities and deep paradoxes.

gravityWhereas the field of quantum physics has been able to account for the first three, gravity has remained explainable only in terms of General Relativity (Einstein’s baby). As a result, scientists have been unable to see how the basic forces of the universe interact on a grand scale, and all attempts have resulted in endless infinities and deep paradoxes.

The amplituhedron, or a similar geometric object, could help by removing two deeply rooted principles of physics: locality and unitarity. Locality is the notion that particles can interact only from adjoining positions in space and time, while unitarity holds that the probabilities of all possible outcomes of a quantum mechanical interaction must add up to one.

quantum_field_theoryThe concepts are the central pillars of quantum field theory in its original form, but in certain situations involving gravity, both break down, suggesting neither is a fundamental aspect of nature. As Nima Arkani-Hamed – a professor of physics at the Institute for Advanced Study in Princeton, N.J. and the lead author of the new work – put it: “Both are hard-wired in the usual way we think about things. Both are suspect.”

In keeping with this idea, the new geometric approach to particle interactions removes locality and unitarity from its starting assumptions. The amplituhedron is not built out of space-time and probabilities; these properties merely arise as consequences of the jewel’s geometry. The usual picture of space and time, and particles moving around in them, is a construct.

Photon_follow8And while the amplituhedron itself does not describe gravity, Arkani-Hamed and his collaborators think there might be a related geometric object that does. Its properties would make it clear why particles appear to exist, and why they appear to move in three dimensions of space and to change over time. This is because, as Bourjaily put it:

[W]e know that ultimately, we need to find a theory that doesn’t have [unitarity and locality]. It’s a starting point to ultimately describing a quantum theory of gravity.

Imagine that. After decades of mind-boggling research and attempts at resolving the theoretical issues, all existence comes down to a small jewel-shaped structure. I imagine the Intelligent Design people will have a field day with this, and I can foresee it making it into the new season of Big Bang Theory as well. Breakthroughs like this always do seem to have a ripple effect…

Ending HIV: New Vaccine Holds Promise for a Cure

hiv-aids-vaccineScientists and researchers have been making great strides in the fight against HIV/AIDS in recent years. In addition to developing vaccines that have shown great promise, there have even been some treatments that have been shown to eliminate the virus altogether. And it seems that with this latest development, which was published in Nature earlier this month, there might be a treatment that can double as a cure.

Developed at the Vaccine and Gene Therapy Institute at the Oregon Health and Science University (OHSU), this new vaccine proved successful in about fifty percent of the clinical subjects that were tested, and may be able to cure patients who are currently on anti-retroviral drugs. If successful, this could mean that a preventative vaccine and cure could come in the same package, thus eliminating HIV altogether.

vaccineCurrently, anti-retroviral drugs and HIV vaccine typically aim at improving the immune response of the patient in the long term. However, they are limited in that they can never completely clear the virus from the body. In fact, aside from a very few exceptional cases, researchers have long believed that HIV/AIDS could only be contained, but not completely cured.

The OHSU team, led by Dr. Louis Picker, has been working on its own vaccine for the past 10 years. In that time, their research has shown that an immune response can in fact go beyond containment and systematically wipe the virus out of the body. As with most early vaccine candidates, the study revolves around SIV – a more aggressive virus than HIV that can replicate up to 100 times faster and, unchecked, can cause AIDS in only two years.

HIV_virusPicker and his research team created the vaccine by working with cytomegalovirus (CMV), another virus which is itself persistent, but doesn’t cause disease. In their initial tests, the vaccine was found to generate an immunoresponse very similar to that generated by CMV, where T-cells that can search and destroy target cells were created and remained in the system, consistently targeting SIV-infected cells until the virus was cleared from the body.

For the sake of their clinical trials, simian subjects were used that were infected by the HIV virus. When treated with the team’s vaccine, half of the subjects initially showed signs of infection, but those signs gradually receded before disappearing completely. This sets it apart from other vaccines which also generate an immunoresponse, but one which fades over time.

HIVAccording to Dr. Picker, it is the permanency of the T-cells that allows the immunoresponse to be consistent and slowly eradicate the virus, eventually eliminating it completely from the system. Says Dr. Picker of their trials and the possibilities for the vaccine:

The virus got in, it infected some cells, moved about in various parts of the body, but it was subsequently cleared, so that by two or three years later the monkeys looked like normal monkeys. There’s no evidence, even with the most sensitive tests, of the SIV virus still being there... We might be able to use this vaccine either to prevent infection or, potentially, even to apply it to individuals who are already infected and on anti-retroviral therapy. It may help to clear their infections so ultimately they can go off the drugs.

Currently, Picker and his the team are trying to understand why some of the vaccinated animals did not respond positively, in the hopes of further increasing the efficacy of the vaccine. Once these trials are complete, it could be just a hop, skip and a jump to getting FDA approval and making the vaccine/cure available to the open market.

Cure_for_HIVImagine, if you will, a world where HIV/AIDS is on the decline, and analysts begin predicting how long it will take before it is eradicated entirely. At this rate, such a world may be just a few years away. For those working in the field of medicine, and those of us who are around to witness it all, it’s an exciting time to be alive!

Climate Crisis: A Hurricane-Ready New York Waterfront

terreformONE_harborIn addition to causing extensive damage, Hurricane Sandy demonstrated just how woefully prepared people in New York for major storm surges. When the water began rising back in October, due to intense rainfall and wind, there was little in the way to stop it or break in the incoming flow. As such, plans are now being considered for creating a buffer zone to protect the city from future storms.

Mitch Joachim, the co-founder of Terreform ONE, has a rather novel suggestion for how this could be done. Basically, he wants to submerge old Navy ships in the New York Harbor, creating a “riparian buffer zone” that could better handle large volumes of water. This is just one of many projects his company is involved in, which include improving transportation links in Red Hook and Governor’s Island, and ecologically engineering Brooklyn’s Navy Yard.

terreformONE_harbor1According to Joachim, their firm hit on the idea of using ship hulls to create a walkway that rises up from the harbor floor. In addition to providing protection for New Yorkers, he claims it would be cosmetically pleasing as well:

We thought one way to make gabions really quick is to take hulls from ghost fleets, cut them into sections, and then puzzle-fit the geometry together. It allows over time the transformation of that landscape. Over years of sediment building up, you would have environments that privilege humans at certain points of the day. But then as tide changes occur, you would have aqueous environments that privilege other life besides humans. 

Basically, the walkway would help keep rising tides back in the near future, and would serve as a natural habitat once the tides rise and move in to claim them. By cutting the hulls into clam-like shapes, the organization says that New York could restore a diversified structure to its waterfront, slowing the water before it makes land.

terreformONE_harbor2Joachim points out that dumping junk into New York waterways has a long history, much of it constructive in nature. Parts of Manhattan, like Battery Park City, were built on land created artificially from construction waste. And sinking ships is already one means of disposal, for the sake of creating artificial reefs. The only other method is what is known as “ship breaking”, which is far worse.

This methods of retiring ships involves cutting ships up for scrap and then recycling the usable steel parts. This practice is both environmentally unsound and can lead to toxic chemicals leeching into the ocean, which is why the majority of ship breaking operations occur in developing countries, such as Bangladesh, India, China, Pakistan and Turkey.

terreformONE_harbor3So in addition to offering protection to coastal cities that are currently ill-prepared for the worst effects of Climate Change, reusing ships to augment the world’s harbor fronts could also help reduce the environmental stress we place on other coastlines. It’s like repurposing one problem to deal with two more. Quite clever, when you think about it!

Robot Snakes to Explore Mars?

curiosity_sol-177-1The recent discoveries and accomplishments of the Curiosity and Opportunity rovers have been very impressive. But for some, these successes have overshadowed the limitations that are part of the rover designs. Yes, despite their complexity and longevity (as evidenced by Opportunity’s ten years of service) the robot rovers really aren’t that fast or agile, and are limited when it comes to what they can access.

Case in point, Curiosity is currently on a year-long trek that is taking it from the Glenelg rocky outcropping to Mount Sharp, which is just over 8 km (5 miles) away. And where crevices, holes and uneven terrain are involved, they’ve been known to have trouble. This was demonstrated with the Spirit Rover, which was lost on May 1st, 2009 after getting stuck in soft soil.

robotsnakesAs a result, the European Space Agency is planning on a sending a different type of rover to Mars in the future. Basically, their plan calls for the use of robot snakes. This plan is the result of collaborative study between the ESA and SINTEF – the largest independent research organization in Scandinavia – that sought to create a rover that would be able to navigate over long distances and get into places that were inaccessible to other rovers.

They concluded that a snake-like robot design would open up all kinds of possibilities, and be able to collect samples from areas that other rovers simply couldn’t get into. In addition to being able to move across challenging surfaces, these snake-bots would also be able to tunnel underground and get at soil and rock samples that are inaccessible to a land rover. Curiosity, which despite its advanced drill, is limited in what it can examine from Mars’ interior.

robotsnakes1The researchers envisage using the rover to navigate over large distances, after which the snake robot can detach itself and crawl into tight, inaccessible areas. A cable will connect the robot to the vehicle and will supply power and tractive power – i.e. it can be winched back to the rover. Communication between the pair will be also be facilitated via signals transmitted down the cable.

According to Pål Liljebäck, one of the researchers developing the snake robot at SINTEF, the challenge presents several opportunities for creative solutions:

We are looking at several alternatives to enable a rover and a robot to work together. Since the rover has a powerful energy source, it can provide the snake robot with power through a cable extending between the rover and the robot. If the robot had to use its own batteries, it would run out of power and we would lose it. One option is to make the robot into one of the vehicle’s arms, with the ability to disconnect and reconnect itself, so that it can be lowered to the ground, where it can crawl about independently.

An additional benefit of this rover-snake collaboration is that in the event that the rover gets stuck, the snake can be deployed to dig it out. Alternately, it could act as an anchor by coiling itself about a rock while the rover using the cable as a winch to pull itself free.

robotsnake2Liljebäck and his colleague, Aksel Transeth, indicate that SINTEF’s Department of Applied Cybernetics has been working closely with the Norwegian University of Science and Technology’s (NTNU) Department of Engineering Cybernetics for many years. However, it was only recently that these efforts have managed to bear fruit in the form or their robot snake-rover design, which they hope will trigger a long-term partnership with the ESA.

In addition to researching rover design, Transeth, Liljebäck and other researchers working with the ESA are looking for ways to bring samples from Mars back to Earth. At present, soil and other materials taken from Mars are analyzed on board the rover itself, and the results communicated back to Earth. If these samples could be physically transported home, they could be studied for years to come, and yield much more fascinating information.

And be sure to enjoy this video of the robot snake in action:

The researchers are busy working on a feasibility study assigned to them by the ESA. The ESA and the researchers believe that by combining a rover that can navigate over large distances with a snake robot that can crawl along the ground and can get into inaccessible places, so many more possibilities could be opened up.

Synchronized VR Triggers Out of Body Experiences

Louish.Pixel
“Spirit Levitation: Out of Body Experience” by Loutish.Pixel

An out-of-body experience (OBE) is one of the most mysterious and inexplicable things a human being can endure. But thanks to new science, triggering one may be as easy as getting a person to watch a video of themselves with their heartbeat projected onto it. According to the study, it’s easy to trick the mind into thinking it belongs to an external body and manipulate a person’s self-consciousness by externalizing the body’s internal rhythms.

These findings were made by a team consisting of Dr Jane Aspell – Senior Lecturer in Psychology at Anglia Ruskin University in the UK – and Lukas Heydrich, a Phd Student at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. Together, the two set out to see find how our internal organs contribute to bodily self-consciousness and whether they can be manipulated to induce an OBE.

electrocardiogramThe underlying goal, according to Ruskin, was finding out how our body merges information such as the visual, auditory, and olfactory with information coming from within. How this leads to the perception we call “reality”, and how it could be altered, is what is being studied here for the first time;

If you think about your body, you have several sources of information about it: you can see your hands and legs, you can feel the seat you’re sitting on via vision, you know you are standing upright thanks to your sense of balance etc. There is also a vast number of signals being sent to your brain from inside of your body every second that you are alive: about your heartbeat, your blood pressure, how full your stomach is, what electrolytes are in your blood, how fast you are breathing.

For their experiment, they attached 17 participants to electrocardiogram sensors and had them view videos of their own bodies through virtual reality goggles so that their body appeared to be two meters (6.5 ft) in front of them. Participants were then shown their own heartbeats in the form of a flashing outline around their “body doubles” that pulsed in sync with their own.

outofbody-1After a few minutes, many of the participants reported sensations of being in an entirely different part of the room rather than their physical body and feeling that their “selves” were closer to their virtual doubles. According to the team, this is the first study that clearly shows how visual signals containing information about the body’s internal organs (i.e. heartbeat) can change their perception of themselves. As Aspell put it:

It confirms that the brain is able to integrate visual information with cardiac information. It seems that the brain is very sensitive to patterns in the world which may relate to self – when the flashing was synchronous with the heartbeat this caused changes to subjects’ self-perception.

While it may sound like technologically-inspired mysticism, the research has several medical applications. One option is to help people with distorted views of themselves – i.e. anorexia, bulimia or other perceptual disorders – to connect with their actual physical appearance. Aspell is currently studying “yo-yo” dieters and says she plans to continue investigating how the internal body shapes who we are.

The Swiss National Science Foundation and the Fondation Bertarelli supported the study which is slated for publication in the APS journal Psychological Science.

The Rescue: A Revenger Mission Update

top_secretAtrum opened the laptop and spun it around in one fluid motion. The screen was now aimed at everyone standing in the small room, a map with a large, square configuration of buildings sitting in a large, green field in the middle of it. The overhead view provided few details, but the setting looked very similar to the one they had just left – a string of warehouses or an industrial park of some kind. Despite how confined they already felt, most felt the need to lean forward to get a better look.

“Thanks to the device the Captain handed off to us, I’ve been able to isolate the frequency of the tracker he had implanted on his person. Once I tuned my instruments to it, I was able to locate him.” He hit a button on the console, and a small, red blinking light appeared in the middle of the largest box-like structure. “This is the last reported location of the Captain. An abandoned truck park outside of Clarksville. This has to be a holding facility of some kind, or a transfer point for prisoners taken by the Intelligence services.”

“It looks weak,” said Pax, noting the frequency and intensity of the signal. “Which means he’s either barely in range or they’ve got him in some kind of hardened bunker.”

“Good eye,” replied Atrum. “I wish I knew more about the tracker he’s got, but the Captain never was one to share.”

“It’s not that far from here. If we move now, we could hit the place before they’re ready.” said Tsunami, drawing herself back up to her full height. Even with her shades on, the look on her face was plain for all to see. As was the fatigue, the poor woman had not slept since they had returned from their last outing. And she seemed destined not to until they made their next move.

“You got my vote,” said Judgement, his skin bristling with several new veins of gold.
Atrum raised his hand. “Now hold on, people. Like I said, this is a transfer point. And as Pax pointed out, its probably a hardened facility of some kind. We all remember what happened the last time we hit one of those. They were ready and waiting.”

“No shit, they were ready. They set us up!” Judgement growled.

From her spot at the outer edge of the circle, Erotica nodded. “And I seem to recall, we still managed to take out the better part of their defenders.”

“Yes, and what are the odds they’ll have so many surprises prepared for us this time around?”

It was Freedom saying this, and Atrum looked to her now. A current was flowing through the group and growing in intensity. He feared as much. After what had happened at the facility, everyone was in a hurry to rectify what they perceived as their own failure. But running headlong into a fight was likely to result in another. Conveying that though, that required some tact. There was a lot of anger in the room right now, and a lot of special powers…

“Look team… chances are, he’s going to be moved from that facility very soon. Our best bet is to try and get him while he’s in transit. The people holding him will be more vulnerable to an attack.”

“And how long will that be?” asked Panacea, her voice mild, but containing an unmistakably steely tone within.

“Before they try to move him? Shouldn’t be long. With prisoners like the Captain, they want to move them to a secure location as quickly as possible. Minimizes the chances that they might escape, or get rescued.”

Bonfire raised his voice next. “So they are anticipating that we might try to rescue him?”

Atrum shrugged. “Standard procedure really. Everything they’ve done thus far makes it look they are treating him like a high-valued enemy asset, lIke a terrorists mastermind. Always assume their followers will try to spring them.”

Judgment growled again. Everyone looked towards him just in time to see his fangs bared. “I don’t like where this conversation is going. And I don’t much like being compared to a terrorist.”

Pax raised his hands and intervened on Atrum’s behalf. “That’s not what he meant, people. Its just a question of procedures, not methods or motives. Right now, they are dealing with us as if we’re a domestic terrorist cell. But that doesn’t mean we are.”

“You’re damn right,” said Tsunami. “They started this fight. And if they want to see terror, they will shortly.”

“Terrorists,” said Panacea with a scoff. “Their methods are based in fear. They hope to paralyze us with terror and intimidate us into submission. They are cowards.”

The group began to raise their voices as one. The thought of striking fear in their enemy’s hearts, of paying back their terror with some terror of their own; it was a like lightning rod that was catching all their rage. Atrum looked to Panacea, and felt a sudden surge of trepidation himself. If even she was speaking of vengeance, then their situation was truly dire.

He raised his hands one more time and asked for calm. “Hold on, people! We need to be careful about going off half-cocked. If we try to rescue the Captain now, from this holding facility, we’re likely to hit them when they’re most prepared.”

“He’s right,” said Pax. “There’s no guarantee this isn’t an ambush too. For all we know, they’re waiting for us to make a move, to commit ourselves prematurely and run into another carefully laid trap.”

“Yeah, and while we’re waiting, what happens to the Captain?” asked Styka. She was joined by Freedom and Tsunami, both of whom began to voice their concern for his well being in Pax’s direction.

“For all we know, they’re torturing to death. He doesn’t have the ability to heal like you do.”

“And he can’t exactly just will himself out of that place. He’s stuck there until we free him. Helpless and alone.”

“No way!” said Judgement. “He’s not alone! He’s always been there for us, and we’re going to be there for him, dammit. Come hell or high water.”

Many began to voice their assent. Others began to avert their eyes, no doubt because they were having a hard time keeping their emotions in check. Anger wasn’t the only thing running the group like a current. One didn’t have to be a telepath to sense that their was a terrible amount of guilt and grief in the room as well.

“Okay,” said Atrum finally. “We’re going to be there for the Captain. But we need to do it in such a way that won’t put his life in danger. And won’t run the risk of failure. That’s not what the Captain would want. He’d be the first to tell us to play this smart.”

A short, tense silence followed. When someone did speak again, it was Angel, and Atrum could sense what she was going to say before he said it.

“I can’t help but notice that since the Captain’s departure, you’ve been stepping in to fill his shoes.” She looked to Pax next. “The two of you in fact have been acting like you’re giving the orders now. Am I the only one who notices this?”

Several more people exhibited the same combination of sudden anger, anger which they were directing at him and Pax now. It was predictable, so much emotion looking for an outlet. And since he was telling them to sit on it and wait, it was inevitable it would be directed at him. Out of desperation, he reached out to Styka and Tsunami ,using their shared telepathic link.

[I’m losing them here. I could use some help.]

Tsunami didn’t even respond. Her thoughts had become a wall, her emotions as cold and impenetrable as the look on her face. Styka answered him, but was not much more receptive.

[Don’t try to avoid them. It’s disrespectful.]

[Please. They’re not listening to reason.]

[Who’s reason? I don’t agree with your plan as it is. Don’t ask me to speak for it.]

[Fine. We can certainly disagree as to how to proceed. But the last thing we need is people turning on each other.]

Styka emitted an audible sigh. In real-time, people were beginning to shout at each other, most in Atrum’s or Pax’s direction. Few seemed to be coming to their defense, but it didn’t really matter. Even those who were in agreement seemed to be attacking each other with their words now.

Atrum reached out to Tsunami again. [Please, you can see they are on the verge of cracking. Help me restore some calm so we can sort this out.]

To his surprise, Tsunami did answer, though not quite as expected. At the far end of the room, the door blew open and a cold gust of wind thundered through. Not a soul was undisturbed by it and everyone was fast looking in Tsunami’s direction. Of all the people present, only she maintained her steady, forward-looking glare until the wind died down and the door slammed shut again.

Waiting for total quiet to return, she finally spoke. “The last thing the Captain said to me was ‘they’ll be another time’. He also told me that Atrum here would know what to do. If he has a plan… then let’s hear him out.”

Atrum was a little surprised.She said the words, but he could feel something menacing not far behind them. Though he could tell she was sincere, he wasn’t sure if what she’d said had been a vote of confidence, or a warning not to screw things up. Either way, he took his cue and continued.

“Like I said, our best bet is to hit these feds when they try to transfer the Captain. They’ll try to do it either by convoy, or by air. Either way, they will be most vulernable at this time. An convoy, even if its stacked with armored vehicles, won’t be unstoppable.”

“Yeah, we proved that much to them last time,” said Angel, looking to those who had been intrinsic in that regard. Standing not far away, Bonfire smiled while Judgment bristled happily.

“And an air lift would be useless. We’ve got several people who could take out escort choppers, and then land on board the one carrying the Captain and whisk him away before anyone could stop them. Either way, we’d have them.”

“What about aerial drones?” asked Freedom, remembering the last one and how it had ruined their day.

On that, Atrum smiled. Reaching to his laptop, he punched a few keys and brought up a new display. In the center, a large green reticule sat, with what looked like a picture of a radio wave bouncing around inside it. “Don’t worry. They caught us with our pants down last time. This time around, we’ll be ready…”

“What is that?” Erotica asked at last.

“That…” Pax interjected, “is the frequency that last drone was using. Next one we see one, we’ll be able to hack it.”

Atrum’s smile broadened, to the point where he was beaming at everyone in the room. “We all saw what just one of those things could do with its big old arsenal of missiles and bombs. Just imagine what kind of hell we could raise with that kind of firepower.”

Again, one did not need telepathy to know that the mood had suddenly changed in the room. What had been anger and grief was slowly morphing into anger and elation. Everyone was beginning to see just how good a plan they had before them, and how much it would hurt the bastards who had put them here…

Panacea was the one to say it, putting all that raw emotion into words.

“When we came together, we took the name of revenge for ourselves,” she said. “Let’s show these men what revenge looks like.”

Powered by the Sun: Bringing Solar to the Developing World

Magnificent CME Erupts on the Sun - August 31All over the world, the goal of bringing development to impoverished communities and nations – but in ways that won’t cause additional harm to the natural environment – remains problematic. As the cases of China and India demonstrate, the world’s fastest growing economies in the 21st century, rapid industrialization may bring economic development, but it comes with a slew of consequences.

These include urban sprawl, more emissions from cars and public transit, and the poisoning of waterways through toxic runoff, chemicals and fertilizers. With seven billion people living in the world today, the majority of which live in major cities and are dependent on fossil fuels, it is important to find ways to encourage growth that won’t make a bad situation worse.

solar_quetsolBut to paraphrase an old saying, crisis is the mother of creative solutions. And amongst forward-looking economist and developers, a possible solution is take the latest advancements in solar, wind, tidal power and biofuels, and tailor them to meet the needs of local communities. In so doing, it is hoped that the developing world could skip over the industrial phase, reaping the benefits of modernization without all the dirty, unhealthy consequences.

Two such men are Juan Rodriguez – a young man who was studying for his business administration at the Universidad Francisco Marroquin in and cut his teeth working for major multinationals like Pampers, Pepto Bismol and Pantene – and his childhood friend Manuel Aguilar, a Harvard graduate with a degree in astrophysics who had gone on to manage a global hedge fund.

solar_quetsol1Three years ago, the two agreed that they were looking for something else and began investigating renewable energy. The result was Quetsol, a company that uses solar energy to improve the quality of life of poor communities living off the electrical grid. In Rodriguez’s and Aguilar’s native Guatemala, such poverty is widespread, with close to 20% of the population living without electricity and relying primarily on candles for light.

This picture of poverty is not exactly news. But after spending a year visiting close to 100 such communities, Rodriguez and Aguilar began to get a clear picture of why solar hadn’t yet succeeded. As Rodriguez put it:

Going to a community and talking about solar power isn’t like going into a community and talking about space travel. It is something that people have already seen, because NGOs have donated solar systems to these communities for decades. In many cases, the systems worked perfectly, but eventually the batteries died, and nobody was there to service them.

solar_quetsol2There solution was to start from the bottom up, using the free-market principle of adapting their approach to meet local needs. This would involve identifying communities before visiting them, taking into account how many people were living without electricity, and what the housing situation was like. When they then visited these communities, they sought out community leaders and held public meetings to learn about them and present their ideas.

Buildings relationships with local communities was a challenge, but so was creating a product for a market whose needs ranged from basic lighting and cell phone charging to powering a refrigerator all day. What they found was that unelectrified communities were relying on terribly inefficient means, ranging from diesel generators to walking to the nearest electrified community to plug in a phone.

solar_quetsol3What was resulted was a Solar Kit, consisting of a 10W Solar Panel, a control box with 7 Amp Battery, 2  LED Bulbs  (and a third optional bulb), and a universal cell phone charger. This kit has the ability to provide five hours of electricity to a house made up of two rooms that measure roughly 25 square meters (225 square feet) each. This is the typical design of homes in rural Guatemala, with one room serving as the bedroom and the other as the kitchen.

With that done, they began working on their sales strategy. Initially, this consisted of working with microfinance credit institutions to help families and communities purchase their solar kits. But after watching too many credit applications get rejected, they took a page from the telecom companies that have made cell phones ubiquitous in Guatemala, Basically, they switched to a pay-as-you-go plan.

solar_quetsol4Today, Quetsol employs a staff of 20 people and boasts board members like Google’s Tom Chi. There product line has also expanded, with the Q1 Solar Kit being supplemented by the Q3, a heavier model that boasts a 75W solar panel, an 85 Amp Battery, and five LED bulbs. The Q2 Kit – a middle of the road model with a 30W panel, 34 amp battery and 3 bulbs – is soon to be released.

But most importantly of all, they have electrified more than 3,500 homes in Guatemala thus far. But that is just a drop in the bucket compared to their long-term goal. Basically, the organization is viewing Guatemala as a stepping stone to all of Latin America as well as Africa by 2015. By 2016, they’d like to tackle the nearly 700 million off-the-grid homes in Asia.

Might sound ambitious, but Rodriguez and Marroquin feel they have the business acumen and social entrepreneurial savvy to pull it off. And given their background and business model, I’d say they are about right. Combined with other technologies that merge local needs with clean, efficient, and renewable means, development in the developing world might actually be an eco-friendly possibility.

News from Space: Curiosity Finds Water!

curiosity_drillsGood news (and bad) from the Red Planet! According to NASA, an examination of the fine-grained soil particles extracted by Curiosity, scientists have concluded that roughly 2 percent of Martian surface soil is made up of water. Though they did not find any traces of organic particles, this latest find confirms that water not only used to exist on the surface of the planet, but can still be found within.

These results bode well for future manned missions to Mars, wherein astronauts could mine the soil for water and study it to advance their understanding of Mars’ history. The findings, which were published today in the journal Science are part of a five-paper segment that began back in August of 2012 and is dedicated to Curiosity’s ongoing mission.

curiosity_drilling2Laurie Leshin, dean of the School Science at Rensselaer Polytechnic Institute and lead author of the paper, said in a NASA press release:

One of the most exciting results from this very first solid sample ingested by Curiosity is the high percentage of water in the soil.

These tests were conducted using the rover’s Sample Analysis at Mars (SAM), a collection of instruments that includes a gas chromatograph, a mass spectrometer, and a tunable laser spectrometer. The first soil samples were collected back in February when the rover used its drill tool for the first time and created a series of holes that were a little over 6 centimeters (2.5 inches) deep and collected the fine dust that resulted.

SAM_NASAOnce placed into the SAM assembly, the samples were heated to 835 degrees Celsius (1,535 degrees Fahrenheit). The gases that were released – which included significant portions of carbon dioxide, oxygen, and sulfur compounds – were then analyzed. The Mars Science Laboratory (MSL) also noticed that quantities of gaseous carbonite were found, which would suggests the presence of water in the Martian soil.

These positive findings were quite welcome, especially in light of the disheartening news last week that Curiosity has yet to crack the methane mystery. Back in 2003, scientists observed methane plumes coming from the planet, a strong indicator of microbial life, which sent scientific and professional interest in finding life on the red planet soaring.

Since that time, no traces of methane have been found, and it was hoped that Curiosity would finally locate it. However, the lack of methane thus far indicates that the rover has little chance of finding existing microbial life on the planet. But the existence of water in such great quantities in the surface soil brings scientists one step closer to piecing together the planet’s past potential for harboring life.

Curiosity_drillingsPaul Mahaffy, a lead investigator for SAM at NASA’s Goddard Space Flight Center, had this to say:

This work not only demonstrates that SAM is working beautifully on Mars, but also shows how SAM fits into Curiosity’s powerful and comprehensive suite of scientific instruments… By combining analyses of water and other volatiles from SAM with mineralogical, chemical, and geological data from Curiosity’s other instruments, we have the most comprehensive information ever obtained on Martian surface fines. These data greatly advance our understanding surface processes and the action of water on Mars.

Given the renewed interest of late in manned missions to Mars – from nonprofit organizations like Mars One, privatized transportation companies like SpaceX, and the unofficial plans to mount a manned mission to Mars by 2030 by NASA – these findings are reassuring. In addition to providing fuel for hydrogen fuel cells for a return craft, subsurface water will be a boon for settlers and terraformers down the road.

mars-one-brian-versteegLeshin confirmed a cubic foot of soil, as opposed to the tiny sample Curiosity analyzed, could yield nearly 2 pints of condensation when heated. So volunteers who are planning on signing up with Mars One, pack your buckets and stoves and be prepared to do a lot of condensing! And perhaps we can expect “moisture farms” to become the norm on a colonized Mars of the future.

The Future is Here: The Pilotless Fighter Jet

QF-16sGoogle may be developing driverless robot cars, but Boeing already has a small fleet a fighter jets that do not require a human pilot. These retired and refurbished QF-16s were turned into special drone craft for use by the US Air Force. But before anyone gets nervous, it should be noted that these specialized drones are strictly flying targets that are meant to assist with aerial combat training.

The test flight of one of the QF-16s took place last week and included an auto-take off and landing as well as an array of aerial maneuvers. The highlights of this test flight were a barrel roll while pulling 7 G’s, climbing to an altitude of 12,000 meters (40,000 feet) and accelerating to a speed of Mach 1.47. All the while, the plane was controlled by two Air Force test pilots on the ground.

drone-strikeIncorporating the latest in unmanned controls, these fighter jets will act as more realistic targets than the older generation of QF-4 unmanned aircraft – which are refurbished F-4 Phantoms. Whereas these Vietnam-era fighter craft are incapable of keeping up with modern designs, F-16s are capable of supersonic speeds and 9-G performance, which should help hone pilots for real-world combat missions.

While this is in many ways is just an upgrade on existing methods, it also represents a big step forward in terms of automation and drone warfare. With greater refinements in the technology and a more effective range, it may be possible to remotely pilot any and all combat aircraft in the not-too-distant future. Unmanned Aerial Vehicles (UAVs) may come to mean all aircraft, and not just Reapers and Predators (pictured above).

And of course, Boeing has produced a video of the QF-16s test flight. Enjoy!

News From Space: Manned Europa Mission!

europa-landerWith so much attention focused on Mars in recent years, the other planets of the Solar System have a hard time getting noticed. But lately, Europa has found itself the subject of some interest. In addition to NASA proposing to send a lander there in the near future, a private space organization is thinking of mounting a manned mission to the Jovian moon in search of knowledge and extra-terrestrial life.

This organization is known as Objective Europa, a group made up of  volunteer scientists, conceptual artists, and social-media experts. At the moment, they exist only on the internet. But with time and financial backing, they hope to form a volunteer corps of settlers that would make a one-way trip to Europa and settle the planet while they researched it.

europa-lander-2Inspired by the recent missions to Mars, Objective Europa also believes a mission to this moon would be worthwhile since it is a far better candidate for extra-terrestrial life. Mars, though it is thought to have once hosted life, is a barren and dry world in its present state. Though many are holding out for the discovery of organic particles in the near future, the likelihood of finding any complex organisms larger than a microbe remains extremely low.

Not surprisingly, their group has attracted some big-name celebrities. This includes Kristian von Bengtson, a Danish architect and co-founder of Copenhagen Suborbitals, a nonprofit focused on launching humans into space. Then there’s Michele Faragalli, a rover mobility specialist for a NASA private contractor. Scientist and diver Pierre-Yves Cousteau, son of legendary explorer Jacques Cousteau, is also on the team as an ambassador for the group.

europa_reportCurrently, the group is in Phase 1 of their plan, which is geared towards the gathering of ideas. Towards this end, they have opened up a variety of research topics for discussion on their website. These include investigating the feasibility of a manned mission versus a robotic mission, launch vehicle studies, and cost analysis.Future phases would involve raising funds, and prototyping and testing technology.

What’s more, while they have not yet stated outright how they plan to fund the mission, it seems likely at this point that crowdfunding and sponsorship will come into play. As the goal statement reads on their site:

“Our purpose is to establish the foundation for and carry out a crewed mission to Jovian ice moon Europa through international crowd-research and participation.”

mars-one-brian-versteegIf this is beginning to sound a little bit like Mars One – a similar space organization looking to send volunteers to Mars – then chances are you’ve been paying attention! In terms of their purpose, objectives, and the fact that the trips they are planning would be a one-way, the two organizations are very similar. But even more interesting is what these and other space organizations like them represent.

In an age when private space travel and exploration are beginning in earnest, crowdfunded, volunteer groups are emerging with the common goal of making things happen ahead of anyone else’s schedule. Whereas space was once the exclusive province of government-sanctioned and funded agencies, now the public is stepping in to assume a measure of control.

And thanks to new media and communications, the money, talent, and energy needed are all available. It’s just a matter of bringing them all together!
