Green tech finds (7/22/10)

Infrared photography, a green Motel 6, and solar in the South Pole… this week’s green tech finds.

  • Lower-carbon flying: Air travel is pretty energy and carbon-intensive, but GE’s trying to make flying a bit greener with “software that will help pilots choose the most environmentally efficient flight trajectories taking into account conditions on four dimensions – latitude, longitude, altitude and time.”

  • California’s the green energy leader… right? Maybe now, but according to Alexis Madrigal at The Atlantic, Alaska and Hawaii may have some of the most innovative approaches out there for moving to low-carbon energy sources.

  • Google ups its wind ante: The online giant invested heavily in a North Dakota wind farm earlier this year, and has now entered a deal with the developer of that farm, NextEra, “to sell that wind power to the grid while obtaining access to Renewable Energy Credits (REC) through a Purchase Power Agreement.” (via Triplepundit)

  • But do they still leave the light on? A Motel 6 in Northlake, Texas, has received LEED certification for a wide range of green and efficient features. Check out the interior shots… not what you’d normally expect. (via Earth Techling)

  • Fuel-free compressed air wind power storage: Power storage for renewable energy is one of the “Holy Grails” of clean technology. Start-up General Compression has developed a technology that requires no fuel for the actual air compression… and has received a $750,000 federal grant for scaling up its concept. (via Cleantechnica)

  • Thermal imaging as a weapon against building inefficiency: Chuck Colgan at Cleantechies describes the use of thermal infrared imaging to identify heating and cooling leaks in buildings.

  • Renewable energy in Antarctica: They don’t exactly have a power grid down there, so research stations around the South Pole, in partnership with the National Renewable Energy Laboratory and the National Science Foundation are testing out both wind and solar power generation.

Find anything cooler than what we’ve got here? Let us know about it in the comments…
