Abstract: An electrical energy generator for converting potential energy into electrical energy. The electrical energy generator includes a water tank filled to a predetermined level with a predetermined amount of water. A circulation tube having a top and bottom end which are both connected to the water tank. A first pump is connected to the circulation tube for drawing water from the water tank for circulating through the circulation tube and back to the water tank and a second pump for delivering air to the circulation tube for mixing with the water and delivery to and compression in the water tank. An air engine is connected to receive the compressed air within the water tank and expand the compressed air to release energy contained therein. An electrical generator is connected to the air engine and receives the energy released from the compressed air for generating electricity by conversion of the energy released from the air.
