Clean, safe power from nuclear fusion is the Holy Grail of energy research – but how close is it to reality? A breakthrough in December, when a fusion reaction produced more energy than went into the experiment, suggests it could be. Dr. Sharon Ann Holgate, author of Nuclear Fusion: The Race to Build a Mini-Sun on Earth, joins Andrew Harrison to unpack the science and ask whether this science fiction staple could become fact.
