Otherpower.com has cool photo essays on dozens of home-brew alternative energy sources, most of which are actually in use, supplying power to a collective of inventors / fringe-dwellers. Their newest addition (although this one is more of a joke than a viable power source) is the hamster-powered alternator. Also dug the two-way Banki turbine (which turns water energy into power on both the inflow and the outflow), and the Volvo disk brake alternator.
Otherpower.com’s headquarters is located in a remote part of the Northern Colorado mountains, 15 miles past the nearest power pole or phone line. All of our houses and shops run on only solar, wind, water and generator power…not because we are trying to make some sort of political or environmental statement, but because these are the only options available. And we refuse to move to town.
