Green tech finds (6/16/11)


A pedal-powered helicopter, a very low-tech speaker for your iPhone made from bamboo, and an online map of solar power potential for NYC… your green tech finds for the week.

  • The pedal-powered helicopter: Think it’s impossible to achieve this kind of flight on human power alone? Engineering students at the University of Maryland managed to get off the ground for 4.2 seconds (a US national record) in their Gamera helicopter. See more about the project in the video above.

  • Reused wine bottles: New company Wine Bottle Renew claims it can clean pre-consumer wine bottles (from tasting rooms and manufacturers) to the point where they’re better than new… and cheaper, also. (via Earth 911)
