Heavy rain and snow do nuclear fusion
1 H2O+O2->He2++E12+O32- Molecular Nuclear Fusion
Constantly around the world. For free. And every 3 minutes we get a lightening strike
2 H2O+e- ->He2++O++E2
And physics professors want 100 billion a year, not to do nuclear fusion: though they always say THEY MIGHT. They do not. Nature does for free.
My PhD supervisor told me 2000, that the linear flow of hydrogen ions around a torous would NEVER do nuclear fusion.
And so the Great Hadron Collidor does not do nuclear fusion – the biggest science con in history.
