  2. Central oil storage - Wikipedia

    en.wikipedia.org/wiki/Central_Oil_Storage

    Central oil storage (COS), or central storage, is the term used for a communal heating system that began to be utilized in the middle of the twentieth century.. The term also applies to industrial, plant and agricultural applications, all of which may or may not be communal in nature.

  3. Vegetable oils as alternative energy - Wikipedia

    en.wikipedia.org/wiki/Vegetable_oils_as...

    Some vegetable oil blends are used in unmodified vehicles, but straight vegetable oil often needs specially prepared vehicles which have a method of heating the oil to reduce its viscosity and surface tension, sometimes specially made injector nozzles, increased injection pressure and stronger glow-plugs, in addition to fuel pre-heating is used ...

  4. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    Low-power or insulated versions of these devices give off less heat for the air conditioning to remove. The air conditioning system can also improve efficiency by using a heat sink that is cooler than the standard air heat exchanger, such as geothermal or water. In cold climates, heating air and water is a major demand for household energy use.

  5. Energy recycling - Wikipedia

    en.wikipedia.org/wiki/Energy_recycling

    Energy recycling is the energy recovery process of using energy that would normally be wasted, usually by converting it into electricity or thermal energy.Undertaken at manufacturing facilities, power plants, and large institutions such as hospitals and universities, it significantly increases efficiency, thereby reducing energy costs and greenhouse gas pollution simultaneously.

  6. Energy recovery - Wikipedia

    en.wikipedia.org/wiki/Energy_recovery

    Heat recovery is implemented in heat sources like e.g. a steel mill. Heated cooling water from the process is sold for heating of homes, shops and offices in the surrounding area. Regenerative braking is used in electric cars, trains, heavy cranes etc. where the energy consumed when elevating the potential is returned to the electric supplier ...

    en.wikipedia.org/wiki/Food_preservation

    In chemical pickling, the food is placed in an edible liquid that inhibits or kills bacteria and other microorganisms. Typical pickling agents include brine (high in salt), vinegar, alcohol, and vegetable oil. Many chemical pickling processes also involve heating or boiling so that the food being preserved becomes saturated with the pickling agent.

  9. Thermal energy storage - Wikipedia

    en.wikipedia.org/wiki/Thermal_energy_storage

    A steam accumulator consists of an insulated steel pressure tank containing hot water and steam under pressure. As a heat storage device, it is used to mediate heat production by a variable or steady source from a variable demand for heat. Steam accumulators may take on a significance for energy storage in solar thermal energy projects.
