United States Patent 3,980,053 – Google Patents
which depicts a car running by burning hydrogen created by electrolysis powered by the car battery charged by the alternator… so there was no fusion or muons involved, just many gullible people. He claims in the patent that his key innovation was a circuit that increases the electrolysis speed, generating hydrogen fast enough to power a car, as if that was the problem with this concept.
Electrolyze or thermonuclear?
Hydrogen can be burnt in engine. And that is not a problem – in fact very limited alterations are required.
In Soviet Union in 70s hydrogen powered passenger plane TU-154 with cryogenic hydrogen tanks flied.
But hydrogen as such has very non-attractive energy per volume density and electrolyze of water is very energy intensive.
Due to today’s ratio of prices between natural gas and kW*h of electricity industrial scale production of hydrogen is conducted with the help of steam reforming method and not electrolyze. And both methods are chemical and not nuclear.
Here is a link of elecrolizers for hydrogen production from water (in Russian): http://ekb.ru/production/14
In that patent I see not nuclear but conventional electrochemistry cell for splitting water. For running of which the energy is required from externally.
