moRe: Cold Fusion.
I hope they have found *fusion* neutrons, because F&P could fill a book with detractors' apologies...
So, semi-duplication of their initial rig didn't work, that's just cutting-edge research with a raft of potential variables, many unknowable without 2020 (CE) hindsight. IIRC, a lot of superconductivity work has proven *very* difficult to reproduce, while some exasperating alloys work but once, briefly, then re-crystallise...
There was certainly no call for the fire-storm of vituperation: It wasn't as if they were playing with N-rays...

Snag, as hot-fusion folk found back in the 50s, is that there are low-probability reaction pathways that produce *some* neutrons under modest conditions. You can build a science-club rig to do it, but those processes do not readily scale to 'break-even', never mind 'economic'. Five weary decades on, the now-multinational tokomaks are creeping up on the issues...
Gotta wonder if Bussard's Polywell whiffle ball approach will trump them all: At least the power factors seem to scale well...
