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).

摘要： Methode pour convertir de l'energie de radiation telle qu'une radiation laser coherente ou le rayonnement solaire non-coherent en energie electrique en utilisant un systeme d'electrodes magnetohydrodynamiques (MHD) qui comprend les etapes suivantes: 1) former un champ magnetique de striction pour concentrer et diriger des particules chargees en mouvement a travers le systeme d'electrodes MHD; 2) fournir une substance de travail ionisable a l'interieur du champ magnetique de striction et; 3) appliquer de l'energie rayonnante a la substance de travail pour en extraire des particules chargees en mouvement lesquelles sont concentrees et dirigees vers le systeme d'electrodes MHD, pour la production de l'energie electrique. L'energie radiante residuelle et la substance recombinee sont recyclees dans un systeme entierement ferme. Dans une realisation preferee, le champ magnetique de striction est forme le long du grand axe d'une surface reflechissante ellipsoidale et l'energie radiante est focalisee sur les foyers de la surface ellipsoidale. Ainsi l'energie reflechie est constamment refocalisee aux foyers. Dans une autre execution preferee, le champ magnetique est forme le long de l'axe longitudinal d'une enceinte allongee et l'energie radiante est dirigee a travers l'enceinte le long de cet axe longitudinal. L'appareillage permettant d'appliquer cette methode est egalement decrit.

摘要： The production of electrical power by means of magnetohydrodynamic (MHD) generator. A closed duct system (2) is provided containing a mixture of an electrically-conductive liquid, which is preferably liquid metal, and an organic liquid, and heating means, preferably a solar absorber (4), for heating the mixture in the closed system. An MHD-generator (8) is located along the flow path of a two-phase liquid metal-vapour flow formed by the heated mixture. A condensor (10) condenses the two-phase flow to form a single phase flow of metal liquid containing organic liquid droplets. The single-phase flow is pumped, for example by an MHD pump 14, to be reheated by the heating means (4).
