Abstract

A buoyancy prime mover having a wheel rotating within a housing. An upper portion of the housing communicates with a lower portion of the housing through pipes and a blower. The blower pumps high pressure operating gas through a blower pipe into a lower portion of the housing. The housing contains operating liquid having a lower buoyancy than the operating gas. The wheel has a plurality of circumferentially disposed buckets. In operation, the blower pumps operating gas into the lower housing portion, where it bubbles up into the buckets. The greater buoyancy of the operating gas causes the wheel to turn. A venturi pipe connects a gas return pipe to to a venturi disposed within the lower housing portion. A venturi low pressure area pulls operating gas through the venturi pipe into the buckets, which also causes the wheel to rotate. At steady state operation, approximately half the operating gas in the buckets comes from the blower, and about half is pulled in through the venturi. The blower reduces the operating gas pressure in the gas return pipe and increases the operating gas pressure flowing into the housing. The operating gas in that portion of the wheel which is travelling upwards reduces the weight acting on that portion of the wheel and therefore creates a down pressure on that portion of the wheel which is travelling downwards, thus increasing speed and torque. The operating liquid weight in the buckets and the speed of the rotating liquid develop the main rotating power.
