A 25x1cm steam plasma tube at 4 atmospheres produces 1.2MW, once started by a pulse of electric at 2,000V. The lighter from a fluorescent light.
This produces 600kW of raw elctricity. A 4 door car requires under 70kW. So we have a hyper car, that can connect to the national grid at home, and power 700 houses.
9 1mx2cm steam plasma tubes will run a 100MW power station, off 2x10-18cc of regular water a years. The oil age has ended.
