Yes, I agree that "cold fusion" may never be commercial, but the Navy lab recently did confirm excess heat and I believe fusion products like helium in test cells. I think that the palladium lattice at the atomic level allows the hydrogen nuclei to get close enough to fuse without the usual high temperatures, but of course, the reaction may be happening at non-commercial rates. But interesting things, consistant with fusion, do appear to be true.
Good info on the fact that Pd is a "sponge" for hydrogen--I agree that chemical processes will be important for Pd demand. My only point about cold fusion was, whether or not it pans out, research is increasing and that is another source of demand for Pd. Thanks.
