Patent ID: 7061129

Claim:
Electric generator comprising at least one source of pressurized gas, a closed hydraulic circuit, essentially in the form of a ring, containing a solution comprising an electrically-conducting vehicle liquid in which a charge of micro- or nanoparticles of a metal material is dispersed; the hydraulic circuit having at least one inlet port connected to said source so that, when in operation, it receives a flow of pressurized gas capable of causing circulation of said solution within the circuit in a predetermined direction, forming a two-phase gas-liquid mixture therewith, a restriction in the flow cross section, located downstream of said inlet port and calibrated so as to cause an increase in velocity and condensation of said two-phase mixture, and at least one outlet port located downstream from said restriction through which gas mixed with said solution can be released and evacuated from the circuit, magnetic-field-generating means associated with a length of the hydraulic circuit lying between the inlet port and the restriction in cross section capable of generating an induction flux substantially at right angles to the direction of flow of the solution in said length of circuit, and at least one pair of electrodes placed in contact with the solution in that length of the hydraulic circuit and facing each other in a direction essentially at right angles to the lines of force of the magnetic field produced by said generating means and the flow direction of the solution in said length of circuit, the arrangement being such that, when in operation, an electric current whose strength depends on the flow velocity of the solution in said length of the hydraulic circuit, the strength of the associated magnetic field and the electrical resistance between the aforesaid electrodes, flows between said electrodes.
