  • Patent number: 6373161
    Abstract: A rotating machine that can generate standard AC, high-frequency AC, or DC electricity by non-conventional means. The method involves changing the air gap between a pole of a stationary magnet and a ferromagnetic member on a rotating disk-like flywheel. Each time the distance of the air gap changes from a maximum to a minimum and back to a maximum, half a cycle of magnetic flux is produced in the circuit of the magnet. A conductor coil is wound around the magnet so that the half cycle of magnetic flux produces a half cycle of EMF in the conduction coil. The flywheel contains non-magnetic material as well as ferromagnetic material, which may be in the form of discrete bars or be shaped like a gear.

  • Patent number: 6292628
    Abstract: A heater for providing steady-temperature heated water for domestic hot water or hygienic purposes. Water is heated in a drum-shaped tank that is divided into two chambers by a piston that can slide longitudinally within the tank. Attached to the tank is a reverse value that can direct cold water from an inlet into either chamber and direct heated water from the other chamber to an outlet leading to a heated water use. Electric component and a cycle regulator control the direction of water flow through the reverse valve and the direction of motion of the piston. When there is a demand for heated water, the cycle regulator causes the piston to move to expel heated water from one chamber while concurrently cold water enters the other chamber. After heated water is expelled from that chamber, the cycle is reversed. Because cold water and heated water are in separate chambers steady-temperature heated water can be maintained. Either electricity or gas can be used in heat water in the tank.
