  2. Energy transformation - Wikipedia

    en.wikipedia.org/wiki/Energy_transformation

    Fire is an example of energy transformation Energy transformation using Energy Systems Language. Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [1] In physics, energy is a quantity that provides the capacity to perform work or moving (e.g. lifting an object) or provides heat.

  3. Direct energy conversion - Wikipedia

    en.wikipedia.org/wiki/Direct_energy_conversion

    The conversion is based on a Traveling-Wave Direct Energy Converter (TWDEC). A gyrotron converter first guides fusion product ions as a beam into a 10-meter long microwave cavity filled with a 10-tesla magnetic field, where 155 MHz microwaves are generated and converted to a high voltage DC output through rectennas.

  4. Photon-intermediate direct energy conversion - Wikipedia

    en.wikipedia.org/wiki/Photon-Intermediate_Direct...

    Photon-intermediate direct energy conversion (PIDEC) is a scheme for direct conversion of nuclear power to electricity. PIDEC process is somewhat similar [citation needed] to a concept of fluorescent light - as in the CFL, in the nuclear reactor the original type of energy generated is not useful to humans. CFL uses a fluorescent coating on the ...

  5. Emission intensity - Wikipedia

    en.wikipedia.org/wiki/Emission_intensity

    An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).

  6. Transfer of energy - Wikipedia

    en.wikipedia.org/wiki/Transfer_of_energy

    Transfer of energy may refer to: Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. Heat transfer, the exchange of thermal energy via conduction, convection and radiation; Collision, an event in which two or more bodies exert forces on each other over a relatively short time

  7. Conversion reactor - Wikipedia

    en.wikipedia.org/wiki/Conversion_reactor

    For electricity production released nuclear energy in the form of heat is typically used to boil water to turn a turbine-generator. Possibly matter is almost completely converted into energy in the cores of neutron stars and black holes by a process of nuclei collapse resulting in: proton → positron + 938 MeV, resulting in a >450 MeV positron ...

  8. Heat transfer physics - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer_physics

    The macroscopic energy equation for infinitesimal volume used in heat transfer analysis is [6] = +, ˙, where q is heat flux vector, −ρc p (∂T/∂t) is temporal change of internal energy (ρ is density, c p is specific heat capacity at constant pressure, T is temperature and t is time), and ˙ is the energy conversion to and from thermal ...

  9. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    Conversion process Conversion type Energy efficiency Electricity generation: Gas turbine: Chemical to electrical up to 40% Gas turbine plus steam turbine (combined cycle) Chemical to thermal+electrical (cogeneration) up to 63.08% [14] In December 2017, GE claimed >64% in its latest 826 MW 9HA.02 plant, up from 63.7%.
