Abstract
Abstract The invention is an electrical circuit comprising a source of DC power, a plurality of electrolytic cells in which mercury is used as the cathode, and a plurality of fuel cells. The electrolytic cells and fuel cells are connected alternately and electrically in series and a shunt is provided from the cathode of each of the electrolytic cells to the anode of the next but one electrolytic cell. Amalgam produced in the electrolytic cells is used as fuel in the fuel cells to reduce total energy requirements.
