How exactly does it work?

Are you using the bouyancy of HHO in air to help lift the empty buckets back up to the top of a traditional water wheel? Then you burn the HHO at the top as well as the additional HHO at the bottom too?

I think nobel prizes are only given to people who make useful contributions to the world. There have been a million and 1 ideas for perpetual motion, and not one has ever done any good. So you have to build a working model, demonstrate it to a few people, along with enough information for them to build their own, then the floodgates are open. Then comes the prize.
