MHD generators were originally developed because the output of a plasma MHD generator is a flame, well able to heat the boilers of a steam power plant. The first practical design ...
The gap distance between electrodes varies considerably, from less than 0.1 mm in plasma displays, several millimetres in ozone generators and up to several centimetres in CO 2 lasers. Dielectric barrier discharges can also be constructed in a concentric fashion: The high voltage electrode is the outer ring, the ground in the inner capillary ...
The engine house would contain the engine, the generator, the necessary switchgear and fuses, as well as the engine's fuel supply and usually a dedicated workshop space with equipment to service and repair the engine. Wealthy households could afford to employ a dedicated engineer to maintain the equipment, but as the demand for electricity ...
