Through the forces of buoyancy and gravity, the apparatus converts gravitational potential energy from falling heavy buoyant objects into mechanical energy that continually rotates shafts within generators to produce electricity.

A number of heavy buoyant objects (HBOs) cycle through the apparatus simultaneously. Each HBO in the apparatus weighs over 2,000 lbs and produces over 495,000 Nm of gravitational potential energy during its descent inside the gravity chamber of the machine. The HBOs descend three to four at a time, which increases the potential energy up to 1,980,000 Nm. During the descent, the gravitational potential energy of the HBOs is transferred to a chain ladder assembly and converted to kinetic energy that rotates gears attached to twelve 5-MW generators, producing 60 MW of electricity.
