This is why I am still on the fence. Some things say they are on to something, while others seem to indicate cover-ups.
In Rossi's defence, the fact he has units out and running, and is building larger setups, including one to power a plant to make more, says he is either a genious con artist, or he has got something economically viable.
I do not hink it would be that hard to replicate some of the stuff that is out in public. Like the bit about 500C Ni powder in a vaccum, and then just add H2.
I think you should stay on him Giorgio, keep pressing to get to a demo or direct access to anyone that has played with it in person.
People don't judge probabilities well.
One mistake is to try to assign meaning to other people's actions and if they seem incomprehensible concluse "Ah, well, they must have some new physics, or it would not be so murky and confused".
Given all the surrounding facts you don't need direct evidence of it not working to properly conclude that.
But this is theory thread. The clearest direct evidence of all not working is the isotopic analysis. Products with natural abundance of copper. Rossi claiming that he enriches the Ni.
Unwanted AW = 58.2 (Ni58 + Ni60)
wanted Ni62 => E.F. scales as sqrt(3.8)
Ni64 => scales as sqrt(5.8)
(from reading wiki page on isotopic separation, and assuming properly that Rossi has not invented new separation method).
We start with Ni62 = 3.6%, Ni64 = 0.9%
centrifuge enrichment will boost Ni62 and Ni64, at great cost.
For x increase in Ni62 we should get x^sqrt(5.8/3.8) increase in Ni64
[from reading wiki on isotopic separation - pls correct me if wrong. BTW the cost sqrt(3.8/58) compares with the cost of srt(3/238) for U235, about 2 X cheaper than corresponding enrichment of U238. We are increasing Ni62 concentration by 30%. Same as increasing U235 concentration by 15%. (Not to 15%!). Anyone know the cost?]
solving forNi62/Ni64 = 70/30 (natural ratio of Cu65/Cu63)
[just for fun assuming equal amounts of Ni62, Ni64 converted]
4/2.33 = 1.71 = x^(5.8/3.8-1) = x^0.53 => x ~ 1.31
So we get enrichment of Ni62 to 1.31*3.6 ~ 5%, and of Ni64 ~2%
AW Ni62 + H1 - AW Cu^63 = 61.9283 + 1.0078- 62.9296 = 0.0065
AW Ni64 + H1 - AW Cu^65 = 63.9280 + 1.0078 - 64.9278 = 0.0080
So fraction of mass converted is:
(0.05*0.0065 + 0.02*0.008)/59 = 8E-6
So energy released / kg is (3E8)^2*8E-6 = 7E11 J
100g provides 7E10/2.5E6 = 30kW for one month or 10kW for 3 months
What was the powder weight & total claimed energy output of this stuff?
This ball park calculation does not actually disprove anything.
Rossi must have been taking to Focardi, who can do the same calcs :)
