I encourage you to do further research in this area. Many experiments, worldwide, have confirmed some form of “cold fusion,” now known as LENR (for low-energy nuclear reactions).
Cold fusion was not a hoax, just tricky to replicate. Although there still exists no comprehensive theory for LENR, it works regardless, just as fire did before chemistry explained it.
The “tricky to duplicate” is the part that has my BS meter at the needle against the peg on the right side.
Low Energy Nuclear Reaction is kind of an oxymoron. It may exist, but it is of such a minute factor as to be easily dismissed.
Without some kind of encompassing working hypothesis, this is like a kid playing with an A.C. Gilbert home chemistry set.
