Fusion technology promises an inexhaustible supply of clean, safe power. If it all sounds too good to be true, that’s because it is. For decades scientists struggled to recreate a working sun in their laboratories – little surprise perhaps as they were attempting to fuse atomic nuclei in a superheated soup. Commercial fusion remains a dream. Yet in recent years the impossible became merely improbable and then, it felt almost overnight, technically feasible. For the last decade there has been a flurry of interest –and not a little incredulity –about claims, often made by companies backed by billionaires and run by bold physicists, that market-ready fusion reactors were just around the corner.
Until recently the attractions and drawbacks of nuclear fusion reactors were largely theoretical. Within a decade this will not be the case.
