We can easily make the Great Hadron Collidor produce power. We inject the H+ ions as today – only at room temperature and pressure. The other direction, we inject the electrons. The positive ions travel one way. The electrons the other. Why they meat we get hydrogen fission.
1 H++e- ->n0
2 xH++2n0->E3+L+X-ray no radioactive waste.
We get the H+ and e-, from the electrolysis of regular water. And it works so well, we only want 7x10-18cc of water every day: we will never measure it.
A near infinite source of heat. We draw off the hot gas, run a steam cycle to generate 75MW of power, and re-inject the very slightly colder gas.
We only need a small torus – like all universities have in cold storage, from the 1970s: so a 1m torous will happily gives us 25MW – and annual income of 79 million UK pounds a year.
