I do think that the idea I had recently and one that I have been pondering about since is something mundane. Specifically because its so simple. Yet its an abstract one that I would like to know more about it from someone who can take the time to think about it and write a paragraph or two. In short form, the idea I recently had and doesn't seem to be explored on here before either is whether it is possible to archive nuclear fusion that produces excess energy than what goes into the process by targeting multiple streams of deuterium from all possible directions towards one point with a powerful particle accelerators? It seems perfectly possible to me. In it that it would look more like a laser fusion device but instead of lasers one uses powerful particle accelerators that accelerate deuterium and not just photons as in the case of lasers.
