Green tech finds


People-powered gyms, transmitting from turtles in Illinois, and combining flies and poop for good use… your green tech finds for the week.

  • The open-source solar concentrator: Designer Eerik Wissenz claims that his Solar Fire open source solar concentrator concept can harvest power at ten times cheaper than photovoltaics. Check it out in the video above… (via Earth Techling)
  • Powering exercise and recreation facilities with energy harvested from workout equipment is catching on at universities… the Sustainable Cities Collective takes a closer look at Drexel University’s approach.
  • Wind-powered wineries: Solar-powered wineries have gotten a lot of attention, but a number of them are also harvesting wind (or, alternatively, buying wind power credits) to power their operations with clean energy.
  • Interactive map shows effects of global warming: The Union of Concerned Scientists’ new Climate Hot Map allows you to see effects of climate change in specific locations. (via Grist)
  • Animal poop and flies: Turns out there’s some promise for this otherwise nasty combination — researchers at Spain’s University of Alicante are working with the larvae of a tropical fly species to break down animal waste quickly, and also leave usable organic matter behind. The recovered material could be used for biofuels or feed for aquaculture systems. (via Yale Environment 360 and @adamwerbach)
  • Shipping container-palooza: Architects have discovered the shipping container as a building module big time, and the NRW-Forum Düsseldorf is currently displaying over 100 examples of building with containers. Inhabitat has a photo gallery of the display.
  • Turtle tracking in Illinois: A project in Dupage County, Illinois, is trying to help the endangered Blanding’s turtle by tracing twenty-five of them with transmitters to find out what kind of habitat the animals prefer when left to their own devices. (via @terracomchicago)
  • Harvesting light pressure: Yep, even light exerts a small amount of force, and scientists at Rochester Institute of Technology are experimenting with ways to harvest that pressure.

Anything else good out there this week? If you found it, and we didn’t, rub it in our faces in the comments…
