One step to stars

Scientists say they have made a major breakthrough in quest to develop practical nuclear fusion.

Researchers are one huge step closer to harnessing the energy source of the stars.

The JET laboratory, in Oxfordshire, England, has smashed its own world record for the amount of energy it can extract by squeezing together two forms of hydrogen.

If nuclear fusion can be successfully recreated on Earth it holds out the potential of virtually unlimited supplies of low-carbon, low-radiation energy.
The experiments produced 59 megajoules of energy over five seconds (11 megawatts of power).

This is more than double what was achieved in similar tests back in 1997.
"The JET experiments put us a step closer to fusion power," said Dr Joe Milnes, the head of operations at the reactor lab. "We've demonstrated that we can create a mini star inside of our machine and hold it there for five seconds and get high performance, which really takes us into a new realm."
