This article is at Phys.org Breakthrough.However, the breakthrough which gathered most international surprise, even though already predicted at the UT, is that the new 'pitch proportions' result in such a strong reduction in the currents between the wires that there is much less heating of the cables and the cables therefore continue to be superconducting. So the new cables have considerably increased the chance that nuclear fusion energy stations will soon generate power in a reliable way.
