A buoyancy engine having a plurality of pistons in cylinders is immersed in a vessel of liquid. A crankshaft is rotatably mounted on sealed bearings in the vessels walls. The pistons are attached to the crankshaft by connecting rods. The pistons are designed to hold relatively buoyant compressed air injected into them by computer controlled injectors. When operating, the crankshaft has one or more pistons moving upward due to the buoyancy of the air which they contain, and one or more empty pistons moving downward.
