Sorry, I lump all technologies not requiring "hot" fusion together even though they're technically very different. To my knowledge, there's no reliable proof cold fusion as you describe it works, outside of the cold fusion fraternity's claims that is.
There appear to be loopholes in some of the scientific laws. Perhaps there is a way to have cold fusion. Nearly every new invention is touted as the cure for all society's ills but never fulfills such promises.
No doubt there are people worried about too cheap a source of energy that would allow someone to leave an unneeded light burning...
