Economics of Mixed Potassium-cesium Seeding of an Mhd Combustion Plasma.

The high price of pollucite ore, its limited availability, and the need to provide stack removal of so2 present formidable obstacles to the use of pure cesium as a seeding material in mhd power generation. Cost estimates indicate that mixed potassium-cesium seeding is preferable to the use of either pure cesium or pure potassium. Cheaper electricity and higher open-cycle mhd operating efficiencies result from the use of mixed seed. Savings of $3,000,000 per year in power costs for a 1,000-mwe open-cycle mhd powerplant are envisioned if the mixed seeding technique is adopted.
