But in another place (the paper the grandparent comment linked) they're claiming a classic Pons-Fleischmann experiment, where they're just pumping in cold deuterium gas–no heat, no radiation–and say they observed spontaneous nuclear reactions. Party like it's 1989. I agree with the grandparent commenter: zero credibility here, this group is doing nothing but trolling people.
