I think more should be spent on fusion research - I think it is just as likely to produce interesting random spin off technologies, but could also produce huge direct benefits to the earth if it can be made into a safe way to produce energy cheaply. JET has proved it is possible: https://ccfe.ukaea.uk/research/joint-european-torus/ https://ccfe.ukaea.uk/research/joint-european-torus/ ITER is taking JET's work to the next level https://www.iter.org/ https://www.iter.org/ Maybe it can't ever be made cheap or practical but worst case scenario it produces interesting results and spin offs like CERN does now.
