It's been a while since I've done a post because I've been spending all my time looking at the exciting goings on in Washington DC right now! It's Solar Decathlon time - a competition put on by the US Department of Energy's Office of Energy Efficiency and Renewable Energy. Multi-disciplinary teams from Universities across the States, and 1 from Canada, 1 from Puerto Rico and 1 from Madrid have spent the last 2 years developing and building the ultimate Solar House. The results are impressive! This is the entry from Cornell - it's stunning - but how well does it work? We'll find out this week as the houses are run through a series (10 in fact) of tests ranging from architectural design and liveability to how far the team's electric car can go on the excess power produced by the home. Stay tuned!
