Invention Nation

DH introduced me to a cool new show on TV tonight: Invention Nation, shown on the Science Channel. 3 guys travel in a van powered by biodiesel (restaurant grease) to see innovations in power, generated by natural sources. Tonight was an Invention Nation fest of sorts, with several episodes linked back-to-back, so it was a great rainy night to curl up by the fire and discover a new show. We saw several houses heated and cooled purely with ingenious construction designs, a solar-powered pickup truck, a community here in NC called Earthaven, that produces its own power and has many other cool features, and much, much more. If you have access to the Science Channel, I highly recommend it. In fact, I recommend it even if you don't. Go to someone elses' house and watch it. :)
