Have a fine jet of H – or a small flask filled with the gas. Arc an electric field across it, and we get a blinding white light. We also get X-rays, and the surface of the arc reaches 10 million oC. There is a video on Y-Tube about this.
This is troubling, as visible light can only be produced my intense elctric or nuclear reactions. You protest that gas plasmas give off vissible light: btu they lose mass as they do so.
So for the H arc, we convert the gas into a plasma, then elctromagnetic radiation. The neutrons do not leave the glass tube – neither does any radioactive material.

2 1H++r n0 ->Er3+L+X-ray
a 100% convertion of matter into energy. Uranium fission converts 8 neutrons from an atomic mass of 236. 0.25% matter conversion. And creates massively toxic radioactive waste – the first nuclear piles were developed to make Plutonium for the early atomic programme.
As the geothermal water circulates around the Earth, the turbulence, pressure and temperature converts the water
3 H2O+TU+P+T → He2++O2-+gwr
This gammma wave radiation converts plutonium into safer elements. So there si no natural source of Pt.
So if nuclear plants used steam plasma tubes in place of enriched uranium, its power would be 2,500 times cheaper – with no radiative waste.
If we half fill a fission tube with uranium fission waste, and half with steam, the solid wastge would display plasma thinning – and the waste would be consumed.
This would consume some of the energy from the steam plasma.
For this reason we use the more exothermic hydrogen plasma, to consume all the radioactive waste. Read http://www.nature.com/nature/journal/v422/n6928/abs/nature01477.html
This science is fantastically simple and easy to investigate – in undergraduate engineering practicals.
