An apparatus for inducing drive is shown that includes a primary drive shaft and four secondary drive shafts. The primary shaft and secondary shafts are fitted with magnets that are oriented such that when the primary shaft is rotated the secondary shafts are caused to rotate due to attractive or repulsive forces. The primary shaft is connected to and rotated by a rotational energy source such as a motor powered by electricity or a battery, although any source of energy to cause rotation of the primary shaft may be used. Each secondary shaft is fitted with two annular magnetic discs that are oriented to vertically support the weight of the shaft (and any attachments / fittings thereto) above the alternating or generating device. The discs can be arranged to provide either an attractive or repulsive magnetic force between them.

A further improved compact reversing flow catalytic converter with protection from overheating includes an improved valve unit which directs exhaust gases through a container filled with catalytic material to permit a bypass of catalytic material when a temperature of the material exceeds a predetermined threshold. The container defines a U-shaped gas passage that communicates with two chambers at the top of the container. The improved valve unit is mounted to the top of the container and includes two container chamber extension cavities, an improved intake cavity and an improved exhaust cavity. The improved valve unit includes an improved valve flapper and two conjoined valve walls each wall with two openings therethrough. The improved valve flapper rotates around normal central axis between a first, a second and third positions. When overheating of the catalytic material is predicted, a controller relinquishes control of the improved valve flapper and an improved center return mechanism rotates the improved valve flapper to a third position, in which each of the valve openings communicates with both inlet and exhaust ports so that the exhaust gas flow bypasses catalytic material. A fuel injection system under control of the controller is used so that measured amounts of fuel can be injected into the container reaction core to enhance oxidation. The catalytic material is thus protected from damage due to overheating. The advantage is a compact, reliable, highly efficient further improved catalytic converter that is inexpensive to manufacture, durable, and adapted for extended service life. The improved valve may driven by a stepper motor that moves and holds the valve to its three positions including bypass, forward and reverse flow. An alternate version also replaces the oxidizing flow-through monolith with an oxidizing filter trap.

A portable hot water heater for larger-scale applications including emergency use, situations involving hazardous materials, and the like. The hot water heater advantageously efficiently and rapidly heats large quantities of water for providing a stream of hot water for immediate use. The hot water heater includes a pump that can draw water from any suitable water source, a power source, a heating assembly that quickly and efficiently heats the water as it flows through the heating assembly. The heating assembly is attached to a shower head or other fixture.

A microwave water heating system includes a metal casing having an outer wall defining an interior casing chamber. An inner housing is positioned within the casing and includes an outer wall displaced from the casing outer wall to form an insulating vacuum space. The inner housing includes an inlet port connected to an upstream water source and an outlet port connected to a downstream conduit. The casing and inner housing include generally spherical configurations. The inner housing is configured to induce a vortex of a water stream flowing between inlet and outlet ports. At least one magnetron is mounted to the casing for transmitting microwaves into the inner housing for heating the water stream at the vortex. A float valve in the inner housing allows the water stream to flow and be heated upon demand as the valve operates according to upstream and downstream pressure differentials.

A wearable device, such as a garment or containing garment portions, for managing and / or reducing the symptoms of a hot flash in a subject. The device comprises: a first set of components, each comprising a fabric comprising a cooling yarn; a second set of components, each comprising a quick-dry wicking fabric; and a third set of components, each comprising a phase change material fabric, wherein the first set of components are adapted to cover at least a neckline region and a peripheral region that extends adjacently around the armpit and the clavicle of the subject; the second set of components are adapted to cover at least the abdominal muscles and the lumbar regions of the subject; and the third set of components are adapted to cover at least the mammary and the dorsum regions of the subject.

A two-step gasification process and apparatus for the conversion of solid or liquid organic waste into clean fuel, suitable for use in a gas engine or a gas burner, is described. The waste is fed initially into a primary gasifier, which is a graphite arc furnace. Within the primary gasifier, the organic components of the waste are mixed with a predetermined amount of air, oxygen or steam, and converted into volatiles and soot. The volatiles consist mainly of carbon monoxide and hydrogen, and may include a variety of other hydrocarbons and some fly ash. The gas exiting the primary gasifier first passes through a hot cyclone, where some of the soot and most of the fly ash is collected and returned to the primary gasifier. The remaining soot along with the volatile organic compounds is further treated in a secondary gasifier where the soot and the volatile compounds mix with a high temperature plasma jet and a metered amount of air, oxygen or steam, and are converted into a synthesis gas consisting primarily of carbon monoxide and hydrogen. The synthesis gas is then quenched and cleaned to form a clean fuel gas suitable for use in a gas engine or a gas burner. This offers higher thermal efficiency than conventional technology and produces a cleaner fuel than other known alternatives.
