Portable radios aren't generally the province of wow-worthy eco-design, but the Lexon Safe Radio proves to be an exception to the rule. Designed by Elium Studio for Lexon, the green-minded AM/FM radio is made of maize bio-plastic with bamboo trim, giving it a refined, modern look that blows traditional plastic radios out of the water. But the best part: it's powered by hand. Wind the crank for two minutes and you get a half hour of eco-friendly tunes. And with an iPod jack on the side, the Safe Radio also acts as an MP3 amplifier. Great piece.
