What do you think the hydrogen runs are???
"How could this tiny and brief temperature increase possibly be used to power a spacecraft or anything else? (It's not continuous, but only when deuterium is first pumped out.) I guarantee this experiment wasn't suppressed by a conspiracy. The hot fusion guys were probably laughing too hard to care."
The question at this point is "does cold fusion exist at all". This very simply and easily replicable experiment answers that question once and for all, and in the affirmative. Next question....can it be scaled up. This is currently being answered. Celani's latest data is showing 1800 watts/gram for Ni/H and 400 watts/gram for Pd/D. But I'm sure you didn't bother to watch his presentation, since it was only for janitors and other cleaning personnel.
As to how, I thought the "Stirling engine" design proposed in the same set of slides was a very elegant approach to doing precisely what was needed to harness the effect.
And I expect the "hot physicists" are filling their underwear as the data mounts. I wondered why Obama was planning to cancel the "hot physics" fusion effort at MIT.
What do you think the hydrogen runs are???
A possible source of contamination. At the very least they should have run the deuterium through a pristine purifier. Likewise they should have captured the purified deuterium and run it through the purifier again for several runs to see if the effect was maintained. Analysis of the gas before and after, likewise would have been helpful.
But not doing any of those checks and controls is why looking for nothing more than an anomalous effect and then running off to report it to an eager audience of crackpots is bad science. It's too bad NASA promotes and funds such activity in order to get some cheap attention.
Wonder Warthog regurgitates what Celani said to an audience of janitors and secretaries during their lunch break. Why don't you explain in your own words why Celani's claims are true and significant?
What's going to be used to heat the palladium to 360C? What will power the Stirling engine during the majority of the time when there is no effect?
