BBC: How ‘miniature suns’ could provide cheap, clean energy
We’re just five years away from harnessing almost unlimited power from “miniature suns”, some start-ups say: nuclear fusion reactors that could provide abundant, cheap and clean energy.
In a world of global warming caused by our addiction to fossil fuels, there is an urgent need to find sustainable alternative sources of energy.
If we don’t, the future looks decidedly bleak for millions of people on this planet: water and food shortages leading to famine and war.
Nuclear fusion has long been heralded as a potential answer to our prayers. But it’s always been “thirty years away”, according to the industry joke.
Now several start-ups are saying they can make fusion a commercial reality much sooner.
