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.
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!
