But its results are seen as a huge boon for ITER, a fusion megaproject in the south of France supported by the US, China, the European Union, India, Japan, Korea and Russia. The ITER project is 80% built and aims to begin nuclear fusion sometime in 2025-26.
While JET's goal was to prove that nuclear fusion could be generated and sustained, ITER's aim is to produce a tenfold return on energy, or 500 MW of fusion power from 50 MW of fuel put in.
The results are promising, but mastering nuclear fusion as an everyday energy source is still likely a long way off.



The tokamak in Oxford, called the Joint European Torus (JET), has been subject to such extreme heat and pressure that this experiment
is likely the last it will cope with.

In a giant donut-shaped machine known as a tokamak, scientists working in the English village of Culham, near Oxford, were able to generate a record-breaking 59 megajoules of sustained fusion energy over five seconds on December 21 last year. Five seconds is the limit the machine can sustain the power before its magnets overheat.
