摘要： The generator (2) comprises at least one source of pressurized gas (2; 2') and a closed hydraulic circuit (3) containing a solution comprising an electrically conducting vehicle liquid in which a charge of micro- or nanoparticles of a metal material is dispersed. This circuit (3) has
at least one inlet port (3a; 3'a) connected to the source (2; 2') so that, when in operation, it receives a flow of pressurized gas capable of causing circulation of the solution within the circuit (3) in a predetermined direction, forming a two-phase gas-liquid mixture with it,
a restriction in cross section (5), downstream from the inlet port (3a) calibrated in such a way as to cause an increase in velocity and condensation of the two-phase mixture, and
at least one outlet port (3b), located downstream from the restriction (5) through which the gas mixed with the solution can be released and discharged from the circuit (3).
The generator (2) also comprises magnetic field generating devices (7; 8, 9), associated with a length (6) of the hydraulic circuit (3) lying between the inlet port (3a) and the restriction in cross section (5) in order to generate an induction flux (10) at right angles to the direction of flow of the solution in that length of circuit (6), and

at least one pair of electrodes (12, 13) placed in contact with the solution in that length (6) of the hydraulic circuit (3), and facing each other in a direction essentially at right angles to the lines of force (10) of the magnetic field and the flow direction of the solution in that length of circuit (6).

The arrangement is such that, when in operation, an electric current (I) whose strength depends on the flow velocity (v) of the solution in that length (6) of the hydraulic circuit (3), the strength of the associated magnetic field (B) and the electrical resistance (R1) between the electrodes (12, 13) flows between the electrodes (12, 13).
