1. A process for energy efficient recharging of an inner thermal reservoir at an extreme temperature by heat exchange with a surrounding thermal reservoir at a moderate temperature, comprising the steps of:

  • selecting from a plurality of reservoirs in a nested configuration a pair of reservoirs for heat transfer therebetween,exchanging heat between a hot surface of a heat pump and the warmer reservoir of the selected pair, andexchanging heat between a cold surface of the heat pump and the cooler reservoir of the selected pair.
