Abstract
The invention relates to a process producing useful energy from thermal energy. An overall population of mobile particles confined to a unidirectional flow closed circuit of conducting channels (1-2-3-3′-4-1) is subjected to a conservative or effectively conservative force field. The circuit is thermally insulated with the exception of two non juxtaposed areas a first area (2-3) allowing thermal exchange for heating (Qin) from a warmer environment outside the circuit, a second area (4-1) allowing thermal exchange (Qout) for cooling, as necessary, by a colder environment outside the circuit. The closed circuit is provided with a load (3′-4;) designed to convert the energy it receives from the mobile particles flow to a useful output energy. In two portions of the unidirectional circuit located before (3-3′) and after (1-2;) said load, flow velocity vector is parallel or has a component which is parallel to the conservative or effectively conservative force field one portion with a warm flow and the other portion with a cool flow of mobile particles and in that if the density of the chosen mobile particles decreases when the temperature increases, the direction of the conservative fo…
