For nuclear fusion to take place, a large amount of energy is needed.

Given the present state of evidence for cold fusion, the Government would do better to put the money on a horse.

However I was wrong: the quest for fusion is perhaps an example of these problems.

They provide the necessary pressure for nuclear fusion to occur within stars.

Contrast this with the search for practical fusion on Earth.

The two chemists have no nuclear evidence for fusion at all.

And they want to use if for nuclear fusion as well!!

The experiment was the strongest evidence anywhere for cold fusion.

"It's hard to make an economically based argument for fusion," he said.

Deuterium is also a potential fuel for commercial nuclear fusion.
