AI summary

A method and device to optimize the cumulative beneficial effect of harvesting available forms of lost energy, including energy that is lost while a vehicle is in motion (e.g., kinetic energy and energy contained in electromagnetic radiation. The cumulative energy that is recovered is converted to electrical energy which powers the on-board electrolyzer to produce more hydrogen and oxygen while the system is in operation and stationary. Stationary, passive forms of energy (e.g., solar, wind, hydro, etc.) will also be available to power the electrolyzer. The system also contemplates using passive forms of energy to power a non-mobile system which incorporates an internal or external combustion engine in place of a fuel cell. An oxygen injection control device is employed to control the supply of oxygen to the combustion engine.
