The sucessful utilization of a new electric generating technology depends critically on its integration with existing utility grids from the viewpoints of control, protection and stability. the proposed study deals with the integration of one new source technology - magnetohydrodynamic (mhd)… More

Information obtained from the measurement of the electrical conductivity of the earth's crust is of great value in the exploration for and the delineation of resources. this information can also significantly enhance understanding of the evolution of the crust, its current composition and structure,… More

A solid state switch for operation at cryogenic temperature is being developed that will provide multi-megawatt power conditioning in the rapidly expanding field of low temperature electronics. since existing controlled switches are not directly suitable for cryogenic operation, only a fundamental… More

The combination of a magnetohydrodynamic (mhd) generator of the disk type with a (nerva) reactor yeilds an advanced space power system with gigawatt pulse and megawatt continuous operating capability, at low specific mass and high specific enthalpy extraction. the novel aspect of thissystem is the… More

In coal-fired open-cycle magnetohydrodynamic (mhd) powerplants, a key issue is chloride buildup. a further consideration is that under the 1990 clean air act amendments, emission of hydrochloric acid (hci) gas/aerosol from a continuous source must be brought below 10 tons/year. potassium added in… More

The innovative approach of operating power electronics in a crvogenic environment depends criticallv on the availabilitx of controllable semiconductor switches capable of high efficiency operation in the temperature range from about 20 K to 150 K. Thc motivation for developing this type of pouer… More
