NOVELTY - The generator includes an electrolytic cell containing an electrolyte and spaced electrodes (12,13) with power supply connections (19,20) to them. The electrodes are mounted on vertical shafts (15) driven by motors (18) so that they may be spun about a vertical axis to release gas bubbles from the electrode surfaces. The gases are collected separately from a pair of hoods (22) above the electrolyte surface.    USE - For producing separate supplies of oxygen and hydrogen for use as fuel in a motor vehicle IC engine or for using a combination of hydrogen and oxygen to produce a flow of electrons to drive and electric motor used to drive a vehicle.    ADVANTAGE - Avoids need for refillable supply of hydrogen.    DETAILED DESCRIPTION - Preferred Features: A number of pairs of hollow, flexible electrodes are mounted for rotation about their spaced vertical axes in a common bath. A permeable ceramic filter is disposed between the electrodes within the cell to prevent or deter cross flow of gas bubbles through the electrolyte. Each electrode is in the form of a number of horizontal plates mounted in superimposed relationship on a driven upright shaft, with peripheral upstanding protuberances on each plate for partial retention of gas bubbles produced on it. A scraper associated with each electrode is adapted to repeatedly wipe or scrape the gas bubbles from the surface. The generator also includes at least one thermocouple, over a hot junction of which gaseous exhaust flow from an internal combustion engine is passed so that gaseous flow is cooled and condensed to water, with the water being fed as liquid to the electrolytic cell to replenish the electrolyte. Gaseous flow from the exhaust, after cooling, is fed to the inlet manifold of the IC engine to reduce exhaust gas flow to atmosphere.
