Solar-powered bluetooth speaker. Beautiful design, but still a concept. This solar-powered bluetooth speaker looks like an elegant plant of some sort, and would great on your desk, no?

Convert Your Ford Escape to Electric Power. Rapid Electric Vehicles is offering a limited number of electric power conversions for the Ford Escape SUV. As AutoblogGreen reports, the conversions don’t come cheap–on the order of $68k a piece–although the company says it thinks it can get the price down to around $45k with a fleet order of 100 conversions. Yikes. Too expensive for my blood.

The Continuing Allure of Rooftop Wind. Four wind turbines, rising 45-feet above a 22-story building in downtown Portland, Ore., won’t produce a significant amount of power — but that’s fine with the architects who put them there. “This is more about generating knowledge than electricity,” said John Breshears of Zimmer Gunsul Frasca Architects.

30-foot-tall solar sunflowers. The largest public art installation in Austin, Texas is a set of 15, 30-foot-tall “sunflowers” studded with solar power petals. The flowers use the energy gathered during the day to power blue LEDs at night, illuminating the bike path they flank. On top of that, they toss about 15 kilowatts of extra energy into the grid daily.

Solar-Powered Rodent Deterrent. This sonic deterrent for gophers, moles and other burrowing creatures does no real harm and is powered by a built-in solar panel. I think I might need this one for the prairie dogs here!
