  2. Einstein refrigerator - Wikipedia

    en.wikipedia.org/wiki/Einstein_refrigerator

    One variant, the Einstein–Szilard electromagnetic refrigerator used a Einstein–Szilard electromagnetic pump to compress a working gas, pentane. [2] Although the refrigerator was not a commercial success, the Einstein–Szilard pump was later used for cooling breeder reactors , where its inherent reliability and safety were important.

  3. Electromagnetic pump - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_pump

    An electromagnetic pump is a pump that moves liquid metal, molten salt, brine, or other electrically conductive liquid using electromagnetism. A magnetic field is set at right angles to the direction the liquid moves in, and a current is passed through it. This causes an electromagnetic force that moves the liquid.

    This could include the generation of voltage by electromagnetic induction, by changing the gap between 2 electrodes or by a piezoelectric material. If the device has some mechanical functionality such as the deformation of a beam or diaphragm due to stress or strain. If it has a system-like functionality.

    The GeoThermag system showed the ability to produce cold water even at 281.8 K in the presence of a heat load of 60 W. In addition, the system has shown the existence of an optimal frequency f AMR, 0.26 Hz, for which it was possible to produce cold water at 287.9 K with a thermal load equal to 190 W with a COP of 2.20.

  6. Superconducting magnetic energy storage - Wikipedia

    The power conditioning system typically contains a power conversion system that converts DC to AC current and the other way around. Control system. The control system monitors the power demand of the grid and controls the power flow from and to the coil. The control system also manages the condition of the SMES coil by controlling the refrigerator.

  7. Troubleshooting - Wikipedia

    en.wikipedia.org/wiki/Troubleshooting

    Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again.

  8. Van Eck phreaking - Wikipedia

    en.wikipedia.org/wiki/Van_Eck_phreaking

    This high-frequency, high-voltage signal creates electromagnetic radiation that has, according to Van Eck, "a remarkable resemblance to a broadcast TV signal". [3] The signal leaks out from displays and may be captured by an antenna, and once synchronization pulses are recreated and mixed in, an ordinary analog television receiver can display ...

    In a reciprocating quantum heat engine the working medium is a quantum system such as spin systems [16] or an harmonic oscillator. [17] For maximum power the cycle time should be optimized. There are two basic timescales in the reciprocating refrigerator the cycle time τ cyc {\displaystyle \tau _{\text{cyc}}} and the internal timescale 2 π ...
