Chrismb comments makes perfectly sense in regarding to Tc, especially from a commercial cost point of view
Palladium price today is about $.26 per gram. Palladium is a spillover catalyst used in most cold fusion reactors; that is in the Rossi case a catalyst that turns H2 into H so that the H can be more easily absorbed onto the surface of the Nickel powder. Usually, about 1% of the total catalyst weight is spill over catalyst.
Since Rossi is only using a single gram of nickel then the cost of the spill over catalyst would be 1% of $.26 or $0.0026
If Rossi used technetium instead of palladium, its cost per reactor would be about twice as much as Palladium or $0.005 for .01 grams; a half a penny.
Tc is still a radioactive material after all, and who is really going to allow any type of radioactive catalist to be commercialized for home/neighbourhood power generation?
True.
The Rossi reactor will not be permitted to be commercialized for home/neighbourhood power generation.
The reason for the October 1 megawatt demo is to show the feasibility of his reactor in an industrial setting demonstrating utility in an industrial power factor. A 10 kilowatt reactor is too small for the industrial market.
there is so many missing tiles in this puzzle that we might spend the next years discussing about 1000 possible explanations
.
The information in the Rossi patent greatly reduces the set of possibilities to a relative few. I am particularly intrigued by the line in the patent that states nickel powder can be replaced by copper powder.
13. An apparatus according to claim 5,
characterized in that said nickel powder is replaceable
by a copper powder.
I conclude, any metal with a high work function(a metal that holds onto hydrogen really tight at its surface) can be used in this reaction if accompanied by the secret spill over catalyst.
The Rossi process is all made possible by .01 grams of this magic stuff.
