The UK has formally joined forces with a US laser lab in a bid to develop clean energy from nuclear fusion.
Unlike fission plants, the process uses lasers to compress atomic nuclei until they join, releasing energy.
The National Ignition Facility (Nif) in the US is drawing closer to producing a surplus of energy from the idea.
The UK company AWE and the Rutherford Appleton Laboratory have now joined with Nif to help make laser fusion a viable commercial energy source.

Hopefully some progress can be made in this field of research. A commercially viable fusion reactor would be a major breakthrough.
