This project proposes a novel method of continuous energy generation using gravitational potential energy and buoyancy-based recovery. The system is designed to harvest energy from the controlled descent of dense, buoyant spheres within a sealed vertical shaft, and to reset their position passively via fluid displacement principles—achieving cyclical motion with minimal active energy input. Unlike conventional gravity-based energy systems, where energy gained during descent is nullified by the energy cost of lifting the mass back up, this design solves the re-elevation challenge using buoyancy in a sealed water column, allowing for potentially energy-positive cycling under the right conditions. ***PLEASE NOTE: I am after a proof of concept/working prototype, not just the CAD design. ***
