General formula:
efficiency_max = (t_hot - t_cold) / t_hot

This describes how much usable work (physics energy) you can obtain from a ''difference of temperatures'' <code>t_hot</code> and <code>t_cold</code>. The temperatures must be measured in <code>kelvin</code> (or any other units that are relative to absolute zero). <code>efficiency_max</code> is a theoretical maximum [[energy]] efficiency, not quite obtainable in real life.

This applies...
* to any power plants that use a fuel to boil water to make steam to drive a turbine to generate electricity.
** This includes [[coal]], [[natural gas]], [[biomass]] and [[nuclear]] power.
* in reverse, to [[heat pumps]] and [[air conditioning]].
** In this case, it's actually the ''inverse'': <code>efficiency_max = t_hot / (t_hot - t_cold)</code>. In this case, <code>efficiency_max</code> is greater than 1, and is higher when the temperature difference is smaller.
