Hasta La Gadget!

Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

This week Inhabitat shed light on the next generation of solar power as we showcased a spray-on film capable of generating 300% more energy than traditional photovoltaics and a new breed of nanotech cells that can heal themselves like plants. New biofuel projects also broke ground around the world as the US began construction on its first commercial biofuel plant and Canada upgraded a waste plant to be powered by soda and beer. And another farticle, er, article covers a project in Greenpoint, Brooklyn that takes the result of the results of those drinks (methane) and turns it into fuel.

We also interviewed energy efficiency expert David Johnston, who shared 5 tips that could cut your electricity bill by up to 50 percent. And on a more sour energy efficiency note, we were appalled to see this new study that found that LEDs, like CFLs, also contain unsafe levels of carcinogenic toxins. The big (or should we say B.I.G) architecture news of the week was the unveiling of Bjarke Ingels Group’s sloping residential pyramid for midtown Manhattan.

In transportation news, Nissan revealed plans to roll out its Tesla-trouncing ESFLOW electric supercar at the Geneva Auto Show, while Chevrolet announced that the Volt will receive a $5,000 tax rebate in California. We also applauded the US government’s $53 billion plan to jump start high speed rail, while republicans rallied against the movement towards more efficient infrastructure.

We also showcased several stylish examples of wearable eco tech – a set of bio sensors that improve physical and emotional health, and a pair of GPS-enabled snow goggles that are perfect for shredding through uncharted territory. Finally, we shared 10 green iPad cases that are perfect for protecting your e-reader from blustery winter weather.

We’re big proponents of the idea that everything is better with lasers, and a team of researchers at UC Berkeley has created a new type of semiconductor plasmon nanolaser, or spaser, that could eventually find a home in many of your favorite devices. The big breakthrough is that Berkeley’s spaser operates at room temperature — previous spasers could only sustain lasing at temperatures below -250° C — enabling its use in commercial products. Plasmon lasers work by amplifying surface plasmons, which can be confined to a much smaller area than the light particles amplified by conventional lasers. This allows for extreme miniaturization of optical devices for ultra-high-resolution imaging, high sensitivity biological sensors, and optical circuits 100 times faster than the electronic variety. There’s no word on how soon the technology will be commercially available, so you’ll have to wait a bit longer for your first laser computer.

As you’re no doubt aware, some of the precious metals used in consumer electronics — like palladium — can be both pricey and hard to come by, which has prompted some to harvest the materials from old electronics and reuse them, while others have been busily working on more readily available alternatives. Among that latter group are a team of researchers from Japan’s Kyoto University, who have just announced that they’ve managed to create a palladium-like alloy using what’s being described as “present-day alchemy.” More specifically, they used nanotechnology to combine (and “nebulise”) rhodium and silver, which don’t ordinarily mix, into the new composite, which they say could eventually replace the real thing in a whole range of electronics and other products. Unfortunately, it’s not clear when that might happen, but the researchers aren’t just stopping at palladium — they’re apparently already looking at using a similar process to create other alloys.

When it comes to building better batteries, building electrodes with greater surface area is key, and scientists are looking to exotic methods to attract the tiny particles they need. We’ve already seen graphene and carbon nanotubes soak up those electrons, but the University of Maryland has another idea — they’re using the Tobacco mosaic virus (TMV) to generate usable patterns of nanorods on the surface of existing metal electrodes. By simply modifying the germ and letting it do its thing, then coating the surface with a conductive film, they’re generating ten times the energy capacity of a standard lithium-ion battery while simultaneously rendering the nasty vegetarian bug inert.

Meanwhile, the Center for Integrated Nanotechnologies (CINT) at Sandia Labs was more curious how these tiny charges actually work without confusing the forest for the trees, so to speak, so a team of scientists set about constructing the world’s smallest battery. Using a single tin dioxide nanowire as anode, a chunk of lithium cobalt dioxide as cathode, and piping some liquid electrolyte in between, they took a microscopic video of the charging process. See it in all its grey, goopy glory right after the break.

Much like graphene, carbon nanotubes seem to be hitting on all cylinders in the lab. Of course, we can count on one hand finger how many instances we’ve seen them making a difference in “the real world,” but we aren’t giving up hope just yet. Researchers from a cadre of universities have come together to solve one of the most nagging issues when dealing with carbon nanotubes — in prior studies, the bundling of these tubes resulted in a marked decrease in strength, which in turn led to a profuse outpouring of tears. But thanks to a new approach, which mixes in a nondescript polymer, they’ve managed to conjure up a “a high performance fiber that is remarkably tough, strong, and resistant to failure.” More specifically, the resulting material is said to be “tougher than Kevlar, meaning it has a higher ability to absorb energy without breaking.” Notably, this material isn’t stronger than Kevlar, as it’s resistance to failure isn’t quite up to snuff, but you can bet the gurus working on this won’t stop until it is. And then, friends, we will have officially arrived in The Future.

Carbon nanotubes run into magical polymer, become ‘tougher than Kevlar’ originally appeared on Engadget on Thu, 09 Dec 2010 00:57:00 EDT. Please see our terms for use of feeds.
