    • 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).

    • The electricity generator (1) comprises a microcombustor (2) provided with a fuel injector (3) and acting to produce at an exhaust outlet (5) a flow of exhaust gas in plasma state comprising positive ions and electrons separated from one another, and a conversion device (6) coupled to the outlet (5) of the microcombustor (2). The conversion device comprises an electrically insulating duct (7) coupled to the said outlet (5) of the microcombustor (2) and provided in its initial portion (7a) with separation and capture electrodes (13,8;18) for capturing the negative charges (electrons) of the plasma in such a way that downstream the plasma comprises only positive ions (I). After the initial portion (7a) the duct (7) has an intermediate portion (7b) provided with an outer cladding (12) of conductive material insulated from the plasma, the ends of which are connectable to a load(L). In operation the flow of positive ions in the intermediate portion (7a) of the duct (7) electrostatically induces in the conductive cladding (12) a negative charge which propagates in the cladding (12) along the direction of flow of the plasma in the intermediate portion (7b) of the duct (7) thereby generating a flow of electric current in the load (L).
