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.
We also showcased several novel electric vehicles, including the crazy Uno 3 transforming scooter which is now available for pre-order. Alternative fuels also took off as a Kentucky man unveiled a car that runs on bourbon and a mobile greenhouse powered by renewable energy hit the streets of New York City. And from the realm of pedal-powered transportation we brought you the SplinterBike - a bicycle made entirely from wood that can hit a record-breaking 30 miles per hour.
In other news, energy-efficient lighting advanced by leaps and bounds this week as we flipped the switch on IKEA's new solar-powered Solvinden lamp and we spotted a crystalline "Stardust" LED lamp made from sugar at the Milan Furniture Fair. Finally, we shined a spotlight on Katy Perry's debut on American Idol as a LED-studded Extraterrestrial, and we took an exclusive look inside New York City's first LEED gold skyscraper - the Hearst Tower!
