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!
