Burning oil or gas in a 1m burner releases 45kW of heat. A 50x1cm steam plasma at 4 atmospheres releases 1.2MW of heat: though this data is for the less energetic Molecular Nuclear Fusion – none by a free steam plasma.
So our steam plasma does
1 H2Op+TU->E3+L+X-ray No CO2 or hyper toxic radioactive waste.
So no 100 billion insurance per power planet. An electric hammer stops the plasma. Shuts down the plant. So no core melt down, or China syndrome.
A thermoelectric generator will turn into ¼MW of free power. That is 3.7 million as an annual income: the grid pays us. No CO2. No plutonium. No impossible insurance.
So no man-made Climate Change – but that was only ever science fiction from nuclear stooges anyway.
