  2. Human power - Wikipedia

    en.wikipedia.org/wiki/Human_power

    Human power is the rate of work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles, but body heat is also used to do work like warming shelters, food, or other humans. World records of power performance by humans are of interest to work planners ...

    Virgin Galactic. Virgin Orbit. v. t. e. The Apollo program, also known as Project Apollo, was the United States human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), which succeeded in preparing and landing the first men [ 2 ] on the Moon from 1968 to 1972.

  4. Fifth Generation Computer Systems - Wikipedia

    en.wikipedia.org/wiki/Fifth_Generation_Computer...

    The Fifth Generation Computer Systems (FGCS; Japanese: 第五世代コンピュータ, romanized: daigosedai konpyūta) was a 10-year initiative launched in 1982 by Japan's Ministry of International Trade and Industry (MITI) to develop computers based on massively parallel computing and logic programming. The project aimed to create an "epoch ...

  5. Engine - Wikipedia

    en.wikipedia.org/wiki/Engine

    Mechanical energy to power the aircraft's electrical and hydraulic systems can be taken from the turbine shaft, but thrust is produced by expelled exhaust gas. An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. [1] [2]

  6. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    Electricity generation. Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.

  7. Environmental impact of electricity generation - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    Water usage. Water usage is one of the main environmental impacts of electricity generation. [7] All thermal power plants (coal, natural gas, nuclear, geothermal, and biomass) use water as a cooling fluid to drive the thermodynamic cycles that allow electricity to be extracted from heat energy.

  8. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    Electric generator. U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator[1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas ...

  9. Wind power - Wikipedia

    en.wikipedia.org/wiki/Wind_power

    Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into ...
