"I suspect that nano-materials have little to do with it except to increase the surface area which enhances the absorption of the gas."

I think that is probably true for Rossi and Defkalion (as apparently recently shown by Celani...who got even higher power outputs (per gram) than Rossi) who are using pure nickel. But I think a nano-material like Miley's will be shown to allow higher operating temperatures (for both nickel and palladium).

"Some apparently successful experiments have been done with nickle rods..."

Indeed....Piantelli. The Fralick study I mention above is in the same "class" as the Piantelli work....just using palladium and deuterium instead of nickel and hydrogen as Piantelli did.

All these people are making unsupported claims. It's backed up by nothing more than "someone says."
