  2. Magnetic water treatment - Wikipedia

    en.wikipedia.org/wiki/Magnetic_water_treatment

    A 1996 study by Lawrence Livermore National Laboratory found no significant effect of magnetic water treatment on the formation of scale. As magnets affect water to a small degree, and water containing ions is more conductive than purer water, magnetic water treatment is an example of a valid scientific hypothesis that failed experimental ...

  3. Qattara Depression Project - Wikipedia

    en.wikipedia.org/wiki/Qattara_Depression_Project

    The Qattara depression is a region that lies 60 m (200 ft) below sea level on average and is currently a vast, uninhabited desert. Water could be let into the area by connecting it to the Mediterranean Sea with tunnels and/or canals. The inflowing water would then evaporate quickly because of the desert climate.

    First, they cause simple parallel field lines. Second, because the fluid is processed in a disk, the magnet can be closer to the fluid, and in this geometry, magnetic field strengths increase as the 7th power of distance. Finally, the generator is compact, so the magnet is smaller and uses a much smaller percentage of the generated power.

    When this happens, magnetic reconnection may occur in the plasma to release stored magnetic energy as waves, bulk mechanical acceleration of material, particle acceleration, and heat. Magnetic reconnection in highly conductive systems is important because it concentrates energy in time and space, so that gentle forces applied to a plasma for ...

  9. Magnetic refrigeration - Wikipedia

    en.wikipedia.org/wiki/Magnetic_refrigeration

    Thermal contact with the heat sink is then broken so that the system is insulated, and the magnetic field is switched off, increasing the heat capacity of the refrigerant, thus decreasing its temperature below the temperature of the heat sink. In practice, the magnetic field is decreased slowly in order to provide continuous cooling and keep ...
