There is no chemical source of visible light or X-rays. If there is no radioactive material about, we are doing Molecular Nuclear Fusion
1 H2O+TU+e-+M+O2->He2++O3-+E2+X-ray TU=turbulence
If there is no source of electrons, we have water vapour or steam in turbulent flow in a strong magnetic field.
But in heavy rain, we have a source of electrons
So heavy rain produces heat, electrical charge and X-rays.
The positive charge rises above the clouds, and the native falls to the ground. A potential of 5,000 V 100 amps. And we get a lightening down strike – a steam plasma.
When it touches the ground, we get the discharge of the 100 amps, and we make 5 tonnes of helium, using 1.
So lightening gives out X-rays, and produces helium, It also fixes the nitrogen into oxides, that fertilizes all life on Earth. And plant life limits free global CO2 to 2 parts per million.
So all graphs showing increasing levels of CO2 in the air are science fiction – biologically impossible. They never say where the readings were taken.
At a diesel exhaust – or in a nuclear stooges imagination.
As to the Northern lights, the strong magnetic dipole sets up a steam plasma in the air – which does Molecular Nuclear Fusion.
A 50x1cm steam plasma in a glass tube produces a constant 1.2 MW, as it converts 10-17cc or regular water into heat, light and X-rays. Carbon less, free power.
