Article summary

The idea of harnessing the process that powers the Sun has been a dream of scientists for decades – and it is easy to see why.

There is an almost limitless supply of fuel in sea-water and there would be no danger of nuclear meltdown. But actually making a practical fusion-energy source is a huge technical challenge, and massively expensive.
