If you carry one (1) five (5) pound weight up a cliff, you will have wasted some amount of energy, even if you harness energy when you drop that rock. If you carry (10) five (5) pound weights up a cliff, you'll have wasted even more energy! Tremendous. Same thing with bubbles underwater. Your 'machine' will probably do an excellent job at wasting energy. If that's your actual goal, bravo! Can't say it won't work. If you post one thousand (1000) posts of zero (0) value, refuse to accept responses of actual value, but continue to post the original post/diagram, as if it held some value, have you accomplished anything?
