Artists concept view of the interior of the ITER reaction vessel. Nuclear fusion involves creating a plasma of superheated gas to temperatures of more than 200 million degrees C, conditions hot enough to force deuterium and tritium atoms to fuse together and release energy. Fusion takes place inside a 'Tokamak' torus within a giant magnetic field, the only way to contain the heat generated. The ITER reactor is designed to produce 500 MW, 10 times more energy than it consumes. Nuclear fusion is the joining (fusing) of light elements to form heavier elements, which releases large amounts of energy. It is hoped that fusion will be a clean, renewable energy source for the future.

Can a slew of nuclear fusion start-ups deliver unlimited clean energy?

We have been trying to harness the reaction that powers the stars for decades, and now private firms are promising commercial fusion within a decade. Is there any reason to believe them this time?
