  2. Lawson criterion - Wikipedia

    en.wikipedia.org/wiki/Lawson_criterion

    Lawson criterion of important magnetic confinement fusion experiments. The Lawson criterion is a figure of merit used in nuclear fusion research. It compares the rate of energy being generated by fusion reactions within the fusion fuel to the rate of energy losses to the environment.

  3. Fusion energy gain factor - Wikipedia

    en.wikipedia.org/wiki/Fusion_energy_gain_factor

    A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state. The condition of Q = 1, when the power being released by the fusion reactions is equal to the required heating power, is referred to as breakeven , or ...

  4. Net energy gain - Wikipedia

    en.wikipedia.org/wiki/Net_energy_gain

    A net energy gain is achieved by expending less energy acquiring a source of energy than is contained in the source to be consumed. That is =. Factors to consider when calculating NEG is the type of energy, the way energy is used and acquired, and the methods used to store or transport the energy.

  5. Ethanol fuel energy balance - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel_energy_balance

    the amount of energy contained in the final ethanol product; the amount of energy directly consumed to make the ethanol (such as the diesel used in tractors) the quality of the resulting ethanol compared to the quality of refined gasoline; the energy indirectly consumed (in order to make the ethanol processing plant, etc.).

  6. Fusion ignition - Wikipedia

    en.wikipedia.org/wiki/Fusion_ignition

    This corresponds to a total scientific energy gain of 0.7 and a capsule energy gain of 6. [14] While the experiment fell short of ignition as defined by the National Academy of Sciences – a total energy gain greater than one – most people working in the field viewed the experiment as the demonstration of ignition as defined by the Lawson ...

  7. Optimal foraging theory - Wikipedia

    en.wikipedia.org/wiki/Optimal_foraging_theory

    The curve represents the energy gain per cost (E) for adopting foraging strategy x. Energy gain per cost is the currency being optimized. The constraints of the system determine the shape of this curve. The optimal decision rule (x*) is the strategy for which the currency, energy gain per costs, is the greatest.

  8. Spherical tokamak - Wikipedia

    en.wikipedia.org/wiki/Spherical_tokamak

    In order for them to fuse, they must be pressed together with enough energy to overcome this coulomb barrier. [1] The simplest way to do this is to heat the fuel to very high temperatures, and allow the Maxwell–Boltzmann distribution to produce a number of very high-energy atoms within a larger, cooler mix. For the fusion to occur, the higher ...

  9. Gain (electronics) - Wikipedia

    en.wikipedia.org/wiki/Gain_(electronics)

    A gain greater than one (greater than zero dB), that is, amplification, is the defining property of an active device or circuit, while a passive circuit will have a gain of less than one. [4] The term gain alone is ambiguous, and can refer to the ratio of output to input voltage (voltage gain), current (current gain) or electric power (power ...
