It is not often that scientific discoveries hold the promise of saving consumer?s money while protecting the environment and reducing the use of fossil fuels. Define the perfect fuel and it would most lightly be one that burns cleanly, poses no harm to the environment and, above all, is renewable or in limitless supply.

The researchers in the U.S Department of Energy?s Ames Laboratory under a construct with the Astronautics Corporation of America have developed a refrigerator with out a standard gas-compression cooling system. Magnetic refr ....etc

Loop magnetic couplers

Couplers, also known as isolators because they electrically isolate as well as transmit data, are widely used in industrial and factory networks, instruments, and telecommunications. Every one knows the problems with optocouplers. They take up a lot of space, are slow, optocouplers age and their temperature range is quite limited. For years, optical couplers were the only option. Over the years, most of the components used to build instrumentation circuits have become ever ....etc

A magnetic amplifier is a device which controls the power delivered from an a.c. source by employing a controllable non linear reactive elements or circuit generally interposed in series with the load. The power required to control the reactive element or circuit is made for less than the amount of power controlled; and hence power amplification is achieved. The non-linear reactive element is a saturable reactor. When used in a combination with a set of high-grade rectifiers, it exhibits power amplification properties in the sense that small ch ....etc

Power frequency magnetic fields as high as 15,000,000 milligauss are commonly found internally in equipment such as power transformers, motors and generators .Although these fields are almost contained within the equipment ,some leakage will occur. This paper concentrates on magnetic fields in the range of zero to several hundred milligauss. This level of magnetic field may be experienced by the general public as a result of operation of electrical equipment, current carrying lines, house wiring, electrical appliances, lighting equipment or an ....etc
