Maxwell's demon

a hypothetical being that could separate a mixture of hot and cold water into two compartments: hot and cold water, letting the hotter-than-average portion through a trapdoor between the compartments. Maxwell's demon challenges the second law of thermodynamics: when hot and cold water are mixed, it will reach an equilibrium middling temperature.

It has emerged that Maxwell's demon can covert information into energy.
