Utilisation of the process that happens within stars.
Harnessing the mechanism as an energy source.
That is the aim, and it has been since long.
Would there be a role for fusion in a future energy system?
Currently, ITER is being built, in Cadarache, in the South of France. Near Aix-en-Provence is a nuclear facility where the CEA resides as well. ITER will be the first reactor to have an output power tenfold of the input power. That is, 500 MW output power, 50 MW input power. It is only heat and nothing will be done with the power produced. Electricity production will be the task of DEMO to demonstrate for the first time. Development projects are already on their way.
The international collaboration is of an unpreceded scale. China, Russia, US, EU, India, Japan and South-Korea join. It is a global peace project. Starting end cold war. Actually, ITER should have been built by that time. Note that some say that ITER technology is so advanced, it could not have been built with the civilisational status of that time, which may well be true,
And how will DEMO do?
And the next?
And the next ten?
And the next one hundred?
And the next one thousand?
Questions should be asked. Will fusion ever be competitive in an energy market, is one question. How fast, yet another.
We have worked on an article, published in Nuclear Fusion: Fusion: Expensive and Taking Forever?
