… Speaking of houses, the 2009 Solar Decathlon ended a week or so ago down on the Washington Mall. Sponsored by the Dept. of Energy, 20 US and international teams competed to build the most energy-efficient and cool-looking solar powered homes. Team Germany took home 1st Prize for largest net production of electricity. California won best architecture and Minnesota had best engineering. I believe that students from the 7th grade had a chance to visit the exhibition and judge for themselves. Check out this Discovery Channel video for a “window” into the solar house of tomorrow – today. H/T James Williams over at Discovery Earth.
