ABSTRACT:
An apparatus and method are provided that comprise the use of a water-filled vessel having two vertical sections and two horizontal sections that connect the respective upper and lower ends of the vertical sections. A sprocket is mounted for rotation with a horizontal output shaft in one of the horizontal sections, and an idler pulley is mounted for rotation in the other horizontal section. An endless drive chain carrying a plurality of gas receptacles, or buckets encircles the sprocket and the idler pulley within the vessel. A gas inlet is positioned at the bottom of the vessel such that a portion of the gas entering the vessel enters the open ends of the downwardly facing buckets and forces part of the water out of the buckets. The hydrostatic pressure of the water exerts an upward buoyant force on the gas in the bucket moving the bucket upwardly. The hydrostatic pressure of the water decreases as the bucket moves upward causing a corresponding reduction in the pressure of the gas until, at the surface, the gas will have decreased in pressure by the hydrostatic pressure of the water at the inlet of the gas into the vessel. The upward movement of the buckets rotates the sprocket and the output shaft whereby power is produced for use outside of the vessel and the pressure of the gas is reduced.
