magnetohydrodynamic power generator Comparison of the operating principles of (A) a turbogenerator and (B) an MHD generator.

In a magnetohydrodynamic (MHD) power generator, the hot gas is accelerated by a nozzle before entering the channel. The gas typically travels through the channel at a speed in the range of 1,000 to 2,000 meters (approximately 3,300 to 6,600 feet) per second.1
