Green tech finds (7/7/11)

Skiing down a Danish incinerator, seaweed for biofuels, and a solar unit that can save the lives of mothers in the developing world… your green tech finds for the week.

  • The solar suitcase: Alexis Madrigal of The Atlantic takes a look at the WE CARE Solar Suitcase, a compact solar power unit designed specifically for use by physicians and midwives during childbirth in the developing world. Find out more in the video above…

  • The incinerator that doubles as a ski slope: The winning design for a new, more efficient incinerator in Copenhagen incorporates a bit of “hedonistic sustainability,” according to architect Bjarke Ingels: a working ski slope will be built over the structure.

  • German electric plane sets speed record: The eGenius, an electric glider developed by the Institute of Aircraft Design of the University of Stuttgart set a new record for speed for this kind of vehicle: 100 mph. The plane flew 211 miles in 2 hours on less than 56 kWh of electricity. (via Inhabitat)

  • GM to develop natural gas car: The Volt gets all of the attention, but General Motors has plans for other low-emissions vehicles, including a diesel version of the Chevy Cruze, and, now, a natural gas-powered vehicle that it will develop in partnership with Westport Innovations. (via

  • More printable solar cells: Last week it was dye-sensitized solar cells; this week, news from the University of Oregon on research into using inkjet printers to produce thin film solar cells with chalcopyrite (or CIGS). (via Earth Techling)

  • Kelp — the next biofuel feedstock? Researchers at Wales’ Aberystwyth University think kelp might be the next big thing for biofuels… though the time of harvesting makes a big difference in its suitability. (via Fast Company)

  • Making the cloud even greener: Cloud computing already has environmental advantages over more traditional IT infrastructures, but Forester Research has published a report arguing that it could be even greener… Heather Clancy at Greentech Pastures gives a run-down of seven of the tactics that could contribute to a more energy-efficient cloud.
