Floating Elevator is an elevator designed to harvest buoyancy to power itself. By changing the weight of water coming in and going out of the air tank, the elevator will automatically go up or down. Even more, the elevator spins around as it goes up and down, and the spinning energy is harvested to generate power. No power is consumed in any of the movements above. As elevators are widely used, Bubble Elevator will certainly become a new design that brings new economic and environmental benefits.
