  • Patent number: 5938900
    Abstract: A method and apparatus for purifying and treating water includes a first magnetic plug having a plurality of polarizing magnets evenly spaced about the circumference of a circular aperture. The longitudinal axis of each magnet is perpendicular to the aperture with its north pole magnetic field directed radially outwardly and its south pole directed radially inwardly to provide a magnetic charge to water molecules passed through the magnetic plug. The water stream is further passed through a chamber having two electrodes made of a copper/silver alloy. By alternating the polarity between the electrodes, copper and silver ions are released into the water while avoiding fouling of either electrode. The water stream is then passed through a filter assembly and a second magnetic plug to enhance retention of beneficial minerals and ions.

  • Patent number: 5718819
    Abstract: In order to improve a process for the electrolysis of a fluid electrolyte containing cations and anions in an electrolytic cell with a cathode and an anode located opposite the cathode such that primary energy not present in an electrical form, in particular thermal energy from reservoirs having a moderately high temperature, can be used for the electrolysis with lower losses, it is suggested that a current path between the cathode and the anode be closed, that a magnetic field be applied to the electrolytic cell and that a relative movement between the magnetic field and the electrolyte be generated so that on account of the effect of Lorentz forces the cations migrate to the cathode and the anions to the anode and products of electrolysis be formed on the cathode and on the anode in electrolytic reactions, wherein the charge equalization necessary for the electrolytic reactions be carried out by the current path closed between the cathode and the anode.

  • Patent number: 5632870
    Abstract: Electrolytic cell apparatus and methods for generating a useful energy product from a plurality of energy sources. In a preferred embodiment, hydrogen gas is produced at a cathode by transmission of electrons through a low voltage potential barrier to electron flow achieved by careful control of electrolyte constituent concentrations and surface materials on the cathode. A portion of the energy captured in the hydrogen gas is provided by heat transmitting activity of ions dissociated from water at an anode which catalytically dissociates the water and thereby transfers thermal energy from the anode to the ions and other constituents of the cell electrolyte. Thermal energy is replaced in the anode by absorption of heat from the surrounding environment.

  • Patent number: 4151051
    Abstract: A deposition unit having a cathode surface is submerged in a natural body of moving water containing various materials including metallic materials carried by the flow of movement of the water body. The flow of water encompasses the deposition unit and contacts the cathode surface. An electric current at the cathode surface causes electrodeposition of certain materials contained within the flow of moving water. The electrical energy for electrodeposition is derived from a naturally occurring and proximate energy source at the body of water. Energy from tidal flow, from water movement beneath the surface, from wave motion at the upper surface, or from a temperature difference between the upper and lower levels of the water body, operates an electrical generator which supplies the electrodeposition energy. The flow of water relative to the deposition unit cooperatively interacts with magnetic flux emanating from another embodiment of the deposition unit to establish the electrodeposition energy.
