I recall visiting an experimental green technology farm in Wales back in about 1997. One of the things they were doing was composting leftover cardboard by peeing on it and waiting for it to breakdown. They also had a nifty water driven lift, and a big display about tidal power. I wish I could remember where exactly that place was.
