  2. Armstrong effect - Wikipedia

    en.wikipedia.org/wiki/Armstrong_effect

    The electrical charge on the steam was positive, although Faraday discovered that adding turpentine to the water produced a negative polarity. In 1843, Armstrong designed a full-scale electrostatic generator on electrically insulating legs. These machines, with 46 steam jets, he called his "hydroelectric generators".

  3. Free-piston engine - Wikipedia

    en.wikipedia.org/wiki/Free-piston_engine

    Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).

  4. Flash boiler - Wikipedia

    en.wikipedia.org/wiki/Flash_boiler

    A flash boiler differs from the type of monotube steam generator in which the tube is permanently filled with water. In a flash boiler, the tube is kept so hot that the water feed is quickly flashed into steam and superheated .

  5. Steam generator (auxiliary boiler) - Wikipedia

    en.wikipedia.org/wiki/Steam_generator_(auxiliary...

    A steam generator on a ship is an auxiliary boiler which draws high-pressure superheated steam from the vessel's propulsion system [1] to generate low pressure saturated steam. This secondary steam is then used to power auxiliary shipboard engines driving winches or pumps, or to meet any steam requirement that does not require superheating ...

  6. Credit card fraud - Wikipedia

    en.wikipedia.org/wiki/Credit_card_fraud

    A fake automated teller slot used for "skimming". Credit card fraud is an inclusive term for fraud committed using a payment card, such as a credit card or debit card. [1] The purpose may be to obtain goods or services or to make payment to another account, which is controlled by a criminal.

  7. Head-end power - Wikipedia

    en.wikipedia.org/wiki/Head-end_power

    Even older railcars used hot steam for heating, supplied by a steam locomotive. In the period when both steam and electric locomotives ran, some diesel and electric locomotives also had steam boilers fitted, there were also steam generator cars in use and some cars were fitted with coal- or oil-fired boiler. Later, remaining steam locomotives ...

  8. Governor (device) - Wikipedia

    en.wikipedia.org/wiki/Governor_(device)

    A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...

  9. Radioisotope thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Radioisotope...

    Diagram of an RTG used on the Cassini probe. 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.
