“Actually, DEMO will operate at a much higher power than present tokamaks and ITER, which means that you can add more fuel density without limiting the output, in contrast to the Greenwald law.
It also shows that the designs for tokamaks like ITER or DEMO could be “less constrained than previously thought.” With the fuel density being increased two-fold, it could result in a vast improvement in their power output by tokamaks—and finally get us to ignition
“If this study is further validated, especially on machines like ITER, it will certainly help the magnetic fusion community credibly design and optimize future designs for experimental and power-generating facilities.”
