Abstract: A mechanism that efficiently produces oxyhydrogen gas (HHO) in stoichiometric proportions, said mechanism operating by the electrolysis of water whereby one electrode stack measuring approximately 2¼?×2¼? with approximately 100 sq. in. of total surface area produces over 4 liters per minute of HHO gas using 12 volts dc at 30 amps current at atmospheric pressure and 50% to 100% HHO output increase as vacuum is increased.
