is so easy. Lightening is set up by heavy rain. The turbulent intersection of rain drops does Molecular Nuclear Fusion
1 H2O+TU ->He2++O2-+E2+X-ray
Each lightening bolt is a 1.5km steam plasma, set up by heavy rain: the positive charges collects above the clouds, the negative falls to the ground.
I make 5 tonnes of Molecular Nuclear Fusion, as it does 1.
Annual nature gets 1040 W of energy from this source – each lightening bolt release 2.5x1030 W as heat, light and other electromagnetic radiation.
So a 50x1cm tube at 4 atmospheres should release a constant 1.2 MW – off a quantity of water too small to measure.
Carbon free, non toxic and free power. Hence the collapse in Fossil Fuels prices: even Saudi Arabia is losing money. It has spent its capital reserves, and is now in trading deficit.
A glass tube is so easy to study:
