(Focardi, Piantelli, Brillouin, tests by IH, earlier tests by Levi, recent reports of positive results by me356, Parkhomov, Suhas and others).
Piantelli would be incensed to hear that his experiments lend support to Rossi. I think they have nothing to do with Rossi.
The tests by I.H. produced no heat. I.H. discovered that an empty cell produced apparent 9 times input. Obviously that means the calorimetry did not work.
Levi's earlier test is the only real evidence in favor of Rossi. The Lugano test was faulty and there is no evidence it produced excess heat. It was also fraudulently presented because it turns out Rossi was there the whole time and he was in charge. That's what I have heard lately. I do not know the details.
me356 and Parkhomov have not been confirmed. Parkhomov is sloppy. I do not know who Suhas is. The others I have heard of are sloppy and wrong.
Rossi's own 1-year test was an outrageous farce that produced no hint of excess heat.
In short, there is practically no evidence that Rossi's claims are true. Only Levi's first test.
