Oct. 10, 1974 - More Power. A blast of hot gas roaring at 3, 000 miles-perhour down this 60-foot-lon.g shock tunnel at General Electric's Space Sciences Laboratory has smashed the efficiency barrier that has stalled magnetohydrodynamic (MHD) electric power research for the past ten years. Dr. Leo Steg {right), manager of the GE laboratory at Valley Forge, Pa. said the dramatic breakthrough is an important step in Exploring the promise of closed-cycle MHD realistic -energy option for the nation's utilities, GE's closed-cycle MHD research team, headed by Dr. Bert Zauderer (left), achieved the long-sought 20 percent efficiency mark when heat generated in the shock tube was converted to 1, 800-KW of electric power in hundredth-ofasecond bursts by a newly developed MHD generator, The closed-cycle MHD project is sponsored jointly by General Electric and the U. S. Office of Naval Research. MHD may be used to boost efficiencies of power plants of the future to 50 to S0 percent, up from today's 37 percent, while consuming less fuel from the wor1d's shrinking reserves. The Navy is considering MHD applications for simplified, lightweight, and more efficient power and main propulsion systems of the future
