  • Patent number: 8999173
    Abstract: An electrochlorination and electrochemical system for the on-site generation and treatment of municipal water supplies and other reservoirs of water, by using a custom mixed oxidant and mixed reductant generating system for the enhanced destruction of water borne contaminants by creating custom oxidation-reduction-reactant chemistries with real time monitoring. A range of chemical precursors are provided that when acted upon in an electrochemical cell either create an enhanced oxidation, or reduction environment for the destruction or control of contaminants. Chemical agents that can be used to control standard water quality parameters such as total hardness, total alkalinity, pH, total dissolved solids, and the like are introduced via the chemical precursor injection subsystem infrequently or in real time based on sensor inputs and controller set points.

  • Patent number: 8864964
    Abstract: A system employs a closed electrolyzer vessel into which water is circulated, and an electrode plate assembly is immersed to dissociate water into hydrogen and oxygen gases. Only water is used as the electrolyte fluid. An air injector in the water return line injects air bubbling for enhanced dissociation of water. The electrode plate assembly is formed by one or more unit stacks of 7-plates each, including two outer cathode plates, a middle anode plate, and spaced inner plates. The generated gases are maintained in a stable condition by an electromagnetic coil assembly that separates the hydrogen gas from oxygen gas. The system can obtain 180% reduction in fuel usage in a vehicle engine, and 20 times reduction in carbon exhaust. It can obtain a 500% increase in fuel efficiency in an electrical power generator.

  • Patent number: 8753488
    Abstract: An apparatus for growing nano-clusters includes a pair of electrodes separated by an electrode pair spacing and a field generation module that generates a corona discharge across the electrodes. The corona discharge generates an electromagnetic field near the electrodes. A voltage potential across the electrodes is a medium voltage. The field generation module includes a medium voltage module that generates a medium voltage waveform, which is transmitted to the electrodes to generate the corona discharge. The field generation module includes a broad frequency generation module that generates a broad spectrum of frequencies within the medium voltage waveform. A raw material feeder module feeds particles of a raw material through the electromagnetic field. The electromagnetic field with the broad spectrum of frequencies is operative to separate at least a portion of the raw material fed through the electromagnetic field into free atoms.
