Whats cold fusion for getting energy?

Answer 1

It's a fraud -- two scientists messed up a lab experiment, thought they were going to win a Nobel Prize, and ended up being totally embarrassed by the whole thing.

Answer 2

Cold fusion was the name for a process that appeared to generate more power than was put into the reaction. It was thought that this use a process of atomic or nuclear fusion, and happened at room temperature, rather than at the high temperatures found inside a reactor. However, only the 2 discoverers were able to demonstrate it, and nobody else. Wikipedia has an article on it.

Answer 3

Cold fusion is a theoretical fusion reaction that occurs near room temperature and pressure using relatively simple devices. In nuclear fusion, multiple nuclei are forced to join together to form a heavier nucleus, and during that process, energy is released. The only known method of fusion that releases significant energy is the thermonuclear reaction, where temperatures and pressures are tremendous and must be contained within an as-yet technologically impractical fusion reactor - or be released, as by a fusion bomb.

Cold fusion was brought into popular consciousness by the controversy surrounding the Fleischmann-Pons experiment in March of 1989. A number of other scientists have reported replication of their experimental observation of anomalous heat generation in electrolytic cells, but in a non-predictable way, and most scientists believe that there is no proof of cold fusion in these experiments.

Answer 4

I think it is possible. I'm not sure if its every going to be practical. Nuclear fusion is the same process used by the sun to produce energy. The trick is to contain a reaction that has the temperatures and pressures of the sun here on earth.

The idea of cold fusion was based on what happens during cavitation. Thats when gas bubbles form in a fluid due to a sudden drop in pressure, like on ships propellers and inside pumps. Cavitating pumps will destroy themselves. Because when the microscopic bubbles collaspe they implode. Which creates tremendous temperatures and pressures inside the microscopic bubbles. The jets of plasma fired out by these tiny bubbles will cut through steel. (See cavitation damage).

So it could work. I don't know if the experiments actually worked or not for sure.

Answer 5

Mostly a media frenzy. Two chemists who didn't know what they were doing claimed to fuse hydrogen in the lab. The news services ran with it and made it a whole lot more credible than it ever should have been.
