Finding new energy sources is far less important than protecting the reputations of all those bloated professors who publicly claimed that cold fusion is impossible.
Even the top experimenters in the cold fusion field admit they have real difficulty in reproducing their results. If the experimenters can't get past that barrier there's no science there.
Have you actually looked at the process they propose? It just doesn't make any sense.
I mean, how can running a current through something cause nuclei to fuse? It would be like trying to merge two rampaging elephants by throwing baseballs at them! :P
