Claim of US Patent No. 10,716,243

1. An information processing system, comprising:a set of information processing devices forming a plurality of electric circuits powered by a power supply source;
a first closed circuit comprised of ducts that convey a heat transfer fluid, the ducts of the first closed circuit being in direct contact with at least one portion of the plurality of electric circuits, the first closed circuit conveying a heat transfer fluid, the plurality of electric circuits transferring heat to the heat transfer fluid of the first closed circuit;
a second closed circuit comprised of ducts that convey a further heat transfer fluid, the second closed circuit recovering heat stored by the first circuit;
at least one Stirling machine wherein
i) the first closed circuit is adapted to form a hot source of the at least one Stirling machine before contact with the second closed circuit, and
ii) the first closed circuit is adapted to form a cold source of the at least one Stirling machine after contact with the second closed circuit,
wherein when there is a temperature difference between said hot source and said cold source, the at least one Stirling machine produces a mechanical circular movement at an output wheel; and
a generator connected to the output wheel, wherein the circular movement at the output wheel is transmitted to the generator to drive the generator to provide an electric current from said mechanical movement, said electric current providing power to the plurality of electric circuits.
