Climate change: A giant donut-shaped machine just proved a near-limitless clean power source is possible
There’s no silver bullet to the climate crisis, but nuclear fusion may be the closest thing to it. In the quest for a near-limitless, zero-carbon source of reliable power, scientists have generated fusion energy before, but they have struggled for decades to sustain it for very long.
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.
