This one's been swirling around for a tick, but Leviathan Energy's brilliant new turbine is just too good to pass up. Showcased at the Cleantech Forum in California, this contraption would reportedly generate power from the downward movement of water through pipes in a municipal system. In other words, there's potential to conjure up energy from simply flushing one's toilet. Of course, there's nothing revolutionary about yet another hydroelectric generator, but using such a device to grab power from such a dirty place takes things to a whole 'nother level.[Via Inhabitat]
