Nuclear fusion is nature's power source. From the Sun to the most distant stars, the energy that lights up the Universe is released by sticking hydrogen nuclei together to make helium. Since hydrogen is the most abundant element in the Universe, it seems sensible to ask whether we might endeavor to do the same and power ourselves out of our serious energy crisis by building stars on Earth.

The BBC, Dr Brian Cox

A story from the BBC
publicizes the ongoing efforts to create controlled fusion reactions in laboratory conditions. These revolutionary experiments are a prelude to creating a new form nuclear reactor, one with potential to create unlimited stores of clean energy by replicating the reactions that go on at the core of the sun

The videos, 1- 6 are available on Youtube presented by the excellent Dr Brian Cox.

.It's absorbing stuff. The mind boggling numbers thrown out in the first few minutes are the hook, if it's logic you crave. For example," the sun loses 4 million tons per day, mass that is converted to energy". That's one of the most satisfying lines of prose I have ever read. But don't let me sway you. watch for yourself. Here is the first of the six
