Created page with "{{minor|(see Wikipedia page for more detail)}} 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 re..."
