A radioisotope thermoelectric generator ( RTG, RITEG ), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect. This type of generator has no moving parts and ...

Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...
Mueller calculus is a matrix method for manipulating Stokes vectors, which represent the polarization of light. It was developed in 1943 by Hans Mueller . In this technique, the effect of a particular optical element is represented by a Mueller matrix—a 4×4 matrix that is an overlapping generalization of the Jones matrix .
Cogeneration or combined heat and power ( CHP) is the use of a heat engine [ 1] or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover ...
e. Gateway Generating Station, a 530-megawatt combined cycle natural gas-fired power station in Contra Costa County, California. A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called ...
A tower type UPS with one IEC 60320 C14 input and three C13 outlets. A large data-center-scale UPS being installed by electricians. An uninterruptible power supply ( UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.
In 2003 these limits were set at a minimum of 20% and a maximum of 25%. [15] Since July 1, 2007, the mandatory blend is 25% of anhydrous ethanol and 75% gasoline or E25 blend. [16] The lower limit was reduced to 18% in April 2011 due to recurring ethanol supply shortages and high prices that take place between harvest seasons. [17]
