  2. Cherenkov radiation - Wikipedia

    en.wikipedia.org/wiki/Cherenkov_radiation

    Cherenkov radiation glowing in the core of the Advanced Test Reactor at Idaho National Laboratory. Cherenkov radiation (/ tʃ ə ˈ r ɛ ŋ k ɒ f / [1]) is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium (such as distilled water) at a speed greater than the phase velocity (speed of propagation of a wavefront in a medium) of ...

  3. Layered charge storage - Wikipedia

    en.wikipedia.org/wiki/Layered_charge_storage

    Layered or stratified charge storage is hot water storage tank, typically for solar thermal energy. The warmest storage layer is the top storage cylinder and below this there are colder storage layers through natural layering. The water is fed into different storage levels, depending on the available feed temperature and current temperature ...

  4. Steam accumulator - Wikipedia

    en.wikipedia.org/wiki/Steam_accumulator

    Steam can be drawn off as required, either for driving a steam turbine or for process purposes (e.g. in chemical engineering), by opening a steam valve on top of the drum. . The pressure in the drum will fall but the reduced pressure causes more water to boil and the accumulator can go on supplying steam (while gradually reducing pressure and temperature) for some time before it has to be re-char

  5. Kelvin water dropper - Wikipedia

    en.wikipedia.org/wiki/Kelvin_water_dropper

    The opposite charges which build up on the buckets represent electrical potential energy, as shown by the energy released as light and heat when a spark passes between them. This energy comes from the gravitational potential energy released when the water falls. The charged falling water drops do work against the opposing electric field of the ...

  6. Storage water heater - Wikipedia

    en.wikipedia.org/wiki/Storage_water_heater

    Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.

  8. Triboluminescence - Wikipedia

    en.wikipedia.org/wiki/Triboluminescence

    It is the emission of light from the fracture (rather than rubbing) of a crystal, but fracturing often occurs with rubbing. Depending upon the atomic and molecular composition of the crystal, when the crystal fractures, a charge separation can occur, making one side of the fractured crystal positively charged and the other side negatively charged.
