2. Energy storage - Wikipedia

   en.wikipedia.org/wiki/Energy_storage

   Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with ...

3. Lighter - Wikipedia

   en.wikipedia.org/wiki/Lighter

   An ignited lighter Disposable lighter. A lighter is a portable device which uses mechanical or electrical means to create a controlled flame, and can be used to ignite a variety of flammable items, such as cigarettes, butane gas, fireworks, candles, or campfires.

4. Home energy storage - Wikipedia

   en.wikipedia.org/wiki/Home_Energy_Storage

   Usually, energy is stored in lithium-ion batteries, controlled by intelligent software to handle charging and discharging cycles. Companies are also developing smaller flow battery technology for home use. As a local energy storage technologies for home use, they are smaller relatives of battery-based grid energy storage and support the concept ...

5. Thin-film lithium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Thin-film_lithium-ion_battery

   The thin-film lithium-ion battery can serve as a storage device for the energy collected from renewable sources with a variable generation rate, such as a solar cell or wind turbine. These batteries can be made to have a low self discharge rate, which means that these batteries can be stored for long periods of time without a major loss of the ...

6. Accumulator (energy) - Wikipedia

   en.wikipedia.org/wiki/Accumulator_(energy)

   An accumulator is an energy storage device: a device which accepts energy, stores energy, and releases energy as needed.Some accumulators accept energy at a low rate (low power) over a long time interval and deliver the energy at a high rate (high power) over a short time interval.

7. Superconducting magnetic energy storage - Wikipedia

   en.wikipedia.org/wiki/Superconducting_magnetic...

   Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.
