A computer actuated relay clicks in the small control room at Israel’s Ben Gurion University of the Negev. Nearby, a two story high power generator starts up.
But there’s a strange silence. There’s no whine from high speed turbine blades, no hum from copper generator coils whirring in a magnetic field, no hiss of pressurized, superhot steam. That’s because
Electropaedia writes: "Magnetohydrodynamic power generation provides a way of generating electricity directly from a fast moving stream of ionised gases without the need for any moving mechanical parts - no turbines and no rotary generators. Several MHD projects were initiated in the 1960s but overcoming the technical challenges of making a practical system proved very expensive. Interest consequently waned in favour of nuclear power which since that time has seemed a more attractive option." 4
