Interesting but that doesn't scratch the itch. I imagine something more like crude metalurgist dwarves, assembling a neutrino detector sized ball shaped room, 1 kilometer underground, with demon core shaped device suspended on detonation wires. Aliens thought giving us nuclear fusion would annihilate us without them trying, but we started to using it to make shiny jewelery and fancy chopsticks.
