This week on one of the UK TV channels there is a program where they put a family in a house, but is disconnected from the grid, and all power is supplied by people on cycle generators - but they don't tell the family. The result sounds a bit hilarious (requires 74 cyclists peddling hard to power the on demand shower unit). Program is apparently being done as a demonstrator of how wasteful we are with energy. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
