Of all the tech out there to secure an energy future? Thorium fluoride salt reactors are the clear winner. $30 bn on r and d in that field would be so much better spent rather than the ITER...which is physically interesting but the smelliest most overweight white elephant one could possibly conceive.
You said no politics but physicists should vote thorium fluoride salt. Amazing tech and the story of its invention is up there with Rossi when it comes to pulling a sly one to get investment. Its developer conned the military into thinking it would be able to power an aircraft when he knew full well it wouldn't, had em going for years, long enough to produce an excellent near flawless prototype that can even consume and make safer existing nuclear waste from conventional reactors.
