Curium-250 is the isotope with the lowest atomic number that primarily decays by spontaneous fission, a process that releases many times more energy than alpha decay. Compared to plutonium-238, curium-250 provides about a quarter of the power density, but 95 times the half-life (~8300 years vs. ~87 years).
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
The 2000-watt society concept, introduced in 1998 by the Swiss Federal Institute of Technology in Zurich (ETH Zurich), aims to reduce the average primary energy use of First World citizens to no more than 2,000 watts (equivalent to 2 kilowatt-hours per hour or 48 kilowatt-hours per day) by 2050, without compromising their standard of living.
It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage.

As an example, consider the use of a 10 hp, 1760 r/min, 440 V, three-phase induction motor (a.k.a. induction electrical machine in an asynchronous generator regime) as asynchronous generator. The full-load current of the motor is 10 A and the full-load power factor is 0.8.
A pure homopolar generator (PHG) [1] [2] [3] is an electric generator not requiring brushes or electronics or semiconductor parts to convert torque into direct current. In other words, this homopolar generator only requires theoretical homogeneous or actual (constantly or cyclically) homogenized magnetic field to be able to produce direct current .
