Here the steam plasma tube is the heat source.
A 50x1cm steam plasma tube at 4 atmospheres does a self-sustaining plasma burn, of 1.2MW of heat. We blast air over this tube. And pass this air over a 150kW thermoelectric mains generator.
Getting carbon 0 power for 18 houses. We sell the excess power to the grid, and get 1.2 million annually – why bother working?
90% of the hot air goes into a high radiator, or into a sea cooler. And then vents to the air. So carbon 0 power – which earns a massive income. The rest heats the house.
