magneto-hydro-dynamic (MHD) power generation is one of the examples of a new unique method of power generation. The other non-conventional methods of power generation may be such as solar cells‚ fuel cells‚ thermo-electric generator‚ thermionic converter‚ solar power generation‚ wind power generation‚ geo-thermal energy generation‚ tidal power generation etc. This paper elucidates about Different Energy sources‚ why we are going for non-conventional energy sources‚ Different

ACTI VE M AGNETI C BEARI NGS (AM B) A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact‚ for example‚ they can levitate a rotating shaft and permit relative motion without friction or wear. In active magnetic bearings (AMB) a stable equilibrium is achieved by means of one or more control loops. The use of control loop for maintaining the gap between the shaft and bearing differentiate the active
