Why stop there? Why not turn iron into gold?
Powder.patch..ball FIRE!
Because if you had been paying attention instead of sneering there are several theoretical models that allow for the reaction to copper.
There are several papers posted that describe the process, search is your friend.
Sarcasm you are not so good at...
Sounds like the kind of change our President has brought us.
Because turning iron into anything else, either by fusion or fission uses energy, rather than producing energy. Ever look at the curve of nuclear binding energy?
Rossi may be a huckster running a scam, but his theory as to what is going on is within the realm of physical possibility, at least using standard binding energy calculations. If he ever gives permission for someone else to build an experimental model to his specs and it works, or someone else manages to get energy out of a Ni to Cu transformation in a properly controlled laboratory experiment, then we'll know he isn't.
What Rossi really does is turn bull$#!^ into money.
