A magnetohydrodynamic energy conversion device with an electrically conductive working fluid flowing through a conduit in a magnetic field has permanent magnets aligned for maximum field density for inducing an electric current in the fluid and a multistage cooling system for cryogenically cooling the magnets whereby heat is removed from the device at successive cooling stages having respective different coolants, e.g., water, liquid nitrogen and liquid helium, to maintain the magnets at temperatures low enough to produce high tesla magnetic flux densities in the presence of a high temperature working fluid.

High efficiency magnetohydrodynamic power generation using ultra-high magnetic fields and novel cooling

A magnetohydrodynamic energy conversion device has a tungsten housing containing a working fluid and a conduit leading from and reentering the housing under pressure developed by heating the fluid with by an optical concentrator which directs rays from the sun at the housing. A voltage is developed across electrodes spaced within the conduit as the heated fluid passes therethrough. The fluid may be directed to turn a gas turbine for driving an electric generator.

Magnetohydrodynamic engergy conversion device using solar radiation as an energy source

An energy conversion device for generating electricity includes a heat exchanger adapted to receive heat from a heat source. A closed magnetohydrodynamic (MHD) circuit includes a section for extracting heat from a heat exchanger so as to raise the temperature of the flowable electrically conductive material within the MHD circuit. The heat exchanger includes a heat-conductive support adapted to be heated, and a heat-extracting section of the MHD circuit extracts heat from the support. The support may be a metal plate having a sinuous pipe arrangement in heat-conductive contact against each face, one of these pipe arrangements being part of a circuit for heating the plate and the other pipe arrangement being part of the MHD circuit. The heat source may be combustion of a fuel, solar, geothermal, chemical reaction, or waste heat in the form of a hot gas. The heat conductive support may be a metal tube heated, usually by a hot gas, in which case the heat-extracting section of the MHD circuit includes a helical pipe surrounding the tube. The heat-providing means may include a lens arrangement for concentrating solar radiation on one face of the heat exchanger plate.
