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.

Did you know that the cell phone in your pocket could be causing the collapse of bee colonies? This week Inhabitat reported the alarming news as Swiss researchers confirmed that cell signals confuse bees and are leading to their deaths. We also looked at a Bill Gates-funded plan to power cell phones using dirt, and we spotted a new phone battery that can be charged by yelling at it — much to the chagrin of everyone else on the bus.

Alternative transportation got a boost this week as Japanese engineers unveiled a levitating high-speed electric train that flies over the earth, and we shined a light on Berkeley’s new solar-powered Impulse racer, which is gearing up to blaze a trail in the 1,800-mile World Solar Challenge. It was a big week for biofuels as well as Ford and Georgia Tech unveiled plans to create the first hydraulic hybrid U.S. school bus and UK scientists cooked up a plan to power cars with Cornish pasties.

In other news, this week a New Jersey Toys “R” Us unveiled plans to build the largest solar roof in the United States, and HyperSolar rolled out a magnifying film that can increase the efficiency of photovoltaic panels by 300%. In green lighting news, we watched Google flip the switch on its brilliant Android-controlled LED bulb, and we announced the Philips and Inhabitat Bright Ideas Lighting Design Competition, which is awarding $1,000 to the designer of the most stunning eco-friendly lamp. Finally, we got excited for the start of summer with a look at the Lapin Kulta Solar Kitchen, which will be serving up sun-cooked meals all across Europe!

The New York Times has released a list of the top 10 solar states, and California has come out on top. In fact, California’s solar output makes up 47 percent of all that comes out of the United States.

That puts second place New Jersey at a distant second, with 14 percent. But those two states completely dominate the list, as the rest goes as follows:

• 3. Colorado: 5 percent
• 4. Arizona: 5 percent
• 5. Nevada: 5 percent
• 6. Florida: 4 percent
• 7. New York: 3 percent
• 8. Pennsylvania: 3 percent
• 9. New Mexico: 2 percent
• 10. North Carolina: 2 percent

But not everybody is happy about the influx of solar panels. “It’s just an eyesore,” one New Jersey resident told the Times. The state is currently in the process of a solar revolution, which aims to have 23 percent of New Jersey’s electricity coming from renewable sources.

Going green is de rigeur, so the sun is becoming a much-preferred source of power. However, solar cells’ inefficient harvesting of heliacal energies is a major reason they haven’t usurped the power of petroleum. Good thing the big brains at Oak Ridge National Laboratory are looking to change that with nanocone-based solar technology. The teeny-tiny cones are made of zinc oxide and create “an intrinsic electric field distribution” to improve electrical charge transport within solar cells. We aren’t sure what that means, but we do know the prickly-looking design provides a 3.2 percent light-to-power conversion efficiency that’s a substantial improvement over the meager 1.8 percent offered by today’s flat photovoltaics made of similar materials. That’s 80 percent more efficient, and 100 percent more awesome.

We’ve seen plenty of portable solar chargers in our time, but few have looked quite as versatile as B-Squares — a new collection of 3D modular energy storage devices that can be arranged in various configurations, according to the kind of gadget you’re looking to juice. Developed by MIT grads Jordan McRae and Shawn Frayne, each solar-powered B-Square features a sticky microsuction surface, along with magnetic and electric contacts at each corner, making it easy to connect and arrange them in different formations. Rotating a single square will change its electrical circuit, depending on its adjacent connection. Some B-Squares, for example, feature LED surfaces, allowing you to create solar-powered lanterns, while others have solar panels, or simply serve as rechargeable battery sources. There’s even a square devoted to Arduino boards, along with another surface designed to dock and charge iPhones. McRae and Frayne have already put together a full “recipe book” of different configurations, though the DIY route seems a lot more enticing to us. Their B-Squares are set to leave the prototype phase on May 1st, at an as yet unspecified price. Check them out in video action after the break.

Are you tired of waking up to the same old semiconductor-based solar array? Do you yearn for a change? We know you do and, thanks again to the wonder and mystery of magnetic fields (they’re not just for stopping speech anymore), there’s a new day dawning. University of Michigan scientists were shooting lasers at glass, as they do, and made a remarkable discovery: light passing through a non-conductive surface like glass generates impressive magnetic effects – up to 100 million times greater than expected. The resulting magnetic force could replace the electric effect exploited by current technology, paving the way for “optical batteries.” Though different from the Wysips transparent photovoltaic cell, the technology could have similar applications and may render obsolete those massive solar farms. No need to worry, though — your stylish solar backpack is as fly as it ever was.

Newly discovered properties of light promise better solar batteries, really great tans originally appeared on Engadget on Fri, 15 Apr 2011 18:11:00 EDT. Please see our terms for use of feeds.
