Home > Power station

A power station (also power plant) is a facility for the generation of electric power. The term is also used to refer to the engine in ships, aircraft and other large vehicles.

At the center of any power station is a generator, a device with a crank that produces a voltage when the crank is turned. The energy source harnessed to turn the generator varies widely from installation to installation. It usually involves some manner of heat engine, which transforms thermal energy, often from combustion of a fuel, into rotational energy. These power stations are often easily identified by cooling towers , huge cylindrical chimney-like structures that release the heat in the form of steam. Others use the energy of water ( waves, tides, or rivers confined by hydroelectric dams), wind, or sunlight.

Power setAbstract algebra Algebra Set theory In mathematics, given a set S the power set of S written P ''S or 2''S is the set of all subsets of S''. In formal language, the existence of power set of any set is presupposed by the axiom of power set.

It is a free game that has a large international following and a growing reputation for being fast, fun and no more complex than it needs to be. It comes Power (physics)Mechanical power In physics, power (symbol: P is the amount of work W done per unit of time t''. This can be modeled as an energy flow, equivalent to the rate of change of the energy in a system, or the time rate of doing work, as defined by : where P is PowerPCPowerPC is a RISC microprocessor architecture created by the 1991 Apple- IBM- Motorola alliance, known as AIM''.
