The surface of a lightening bolt is 10millionoC – the temperature of a radiant sun's corona. It is set up by the chaotic interaction of rain drops, giving out X-ray and producing He, as we do Molecular Nuclear Fusion.
1 H2O+O2+TU ->He2++O32-+E2+X-ray
The positive charge rises to above the clouds, the native falls to the ground. At 5,000 V, a partial steam plasma tracks to the ground – this takes ½ MW of power.
When it touches down, we get the up-rush of 100 amps of charge through the steam plasma. This is when we get 10million oC.
And form 5 tonnes of He, as we do Molecular Nuclear Fusion.
A 50x1cm steam plasma tube will generate 1.2 MW of heat. That forms 120 kW. The nation grid will pay 3.6 million UK pounds for this power.
From regular water, with no CO2 of radioactive waste. The plasma does
2 H2O+TU ->E3+L+X-ray
The H ions and electron form neutrons convert the H and O ions into heat, light and X-rays.
Never any Fossil Fuels burn. No enriched Uranium, or production of Plutonium. Safe, clean, free massive power.
