First Light (Oxford University spinout) achieves nuclear fusion
The amount of cynicism around fusion is stupid. It reminds me a lot of the learned helplessness that surrounded the idea of reusable spacecraft.A little engineering later:https://www.youtube.com/watch?v=sf4qRY3h_eoFusion is a harder problem than that but we have no physical reason to believe it is not possible and the surrounding technology like compact higher temperature superconductors has advanced significantly since the 1960s and 1970s.I am typing this on a computer with a ~5nm feature size CPU. Hard things can be done. It takes time, focus, and funding.
