what is meant my cold fusion?

Answer 1

Fusion is the chemical reaction of total binding two hydrogen atoms to form a helium atom. in this reaction a significant amount of energy is exerted. this reaction can occur at very high temperatures, which are provided e.g. in a hydrogen bomb by explosion of initial detonator made of TNT or similar high temperature explosive.

Cold fusion should occur at far more lower temperatures, like normal ambiental temperature, or at most untill 50oC. So far no method for cold fusion was made, although there had been an experiment in 1985-86, when scientists allegedly stated that the cold fusion had been made in laboratory, at environmental temperature. They had even won the Nobel prize for it, but later investigations revealed that there was no successful outcome of that experiment. that scientific scandal was forgotten in almost no time, but the fact that cold fusion has not been produced yet remained.

Answer 2

Cold fusion was supposed to be a nuclear fusion reaction taking place at room temperature. It became famous when scientists at the University of Utah claimed to have observed this phenomenon. This finding was later found to be false. The term "Cold Fusion" has come to represent bad science or an unattainable technological achievement.

Answer 3

In order to achieve energies required for fusion temperatures around 30,000,000 C(or K) are needed. Cold fusion is any reaction that could achieve fusion at significantly lower temperatures.

There is one concept for cold fusion known as muon catalyzed fusion. Basically the electrons in the atom are replaced by muons (you can think of a muon as a heavy electrons). The muons orbit closer to the nucleus. In effect this allows to hydrogen atoms to be closer before the feel repulsion. This decreases the energy required to fusion. In theory it could be achieved at temperatures around 1000K.

All other concepts of cold fusion that I know of are B.S.

Answer 4

The fusion that we're able to accomplish at this moment has to take place at very high temperatures (eg in a hydrogen bomb).

Cold fusion is fusion that takes place at lower temperatures. Currently, no one has been able to accomplish this.

Answer 5

fusion at the temp less than that of stars

Answer 6

It's supposed to be a nuclear reaction that takes place at room temperature. As in a tumbler on your kitchen worktop.

Whether it exists, or can exist, or is fakery or a myth (urban or suburban) remains to be seen.
