This patent describes a buoyancy engine utilizing pistons and crankshaft, comprising: cylinders, disposed in a vessel contained liquid; the vessel sitting on a base and having an air exhaust orifice at its top; hydrodynamically designed pistons, disposed within the cylinders, designed with air holding spaces to hold injected air, and attached by connecting rods to a hydrodynamically designed crankshaft; sealed connecting rod bearings which connect the piston rods to the crankshaft; wrist pins which connected the piston rods to the pistons, the crankshaft supported on sealed bearing in the vessel walls, and which is rotated by the upward motion of the relatively buoyant pistons which are attached; the crankshaft designed so that its lobes to which the pistons are attached are at angles which insure that power developed by pistons in their lift cycle is successively converted into continuing rotational force on the crankshaft; computer-controlled air injectors, programmed to crankshaft rotational speed, positioned to inject air, compressed by a compressor, into the pistons at the bottom of each piston's stroke, the pistons having pistons rings to retain the air in the piston during its upward power stroke; and vents incorporated into their design for the release of air at the top of their power stroke. An exhaust port in each cylinder conducts air released from pistons to be released into the ambient liquid; a flywheel attached to the crankshaft, stores a part of the mechanical energy produced, provides continuity to the series of energy developing cycles of the pistons; a generator attached to the crankshaft, produces electric power from the rotation of the crankshaft.
