Electrogasdynamic energy conversion

Like the earlier magnetohydrodynamic (MHD) concept, EGD conversion is being seriously considered by the utilities as a possible future means for obtaining large-scale production of electric power. Probably the principal advantage of the EGD converter is that a high gas temperature is not a basic requirement. In addition, the EGD system is potentially capable of generating ac power directly at transmission-line voltages with the use of conventional or nuclear energy sources. Following a brief discussion of MHD conversion, this article reviews the basic theory of EGD conversion and describes a converter system now under development.
