Reading the description of the experimental setup Abundo writes only of Hydrogen.
The text below is very interesting besides mentioning Hydrogen gas, gives the idea that, as many guessed on vortex-l, that Rossi's catalyst is indeed iron used to split H2 in H. "il mix di polveri, quando usato con catodi metallici, può contenere polvere catalizzante micrometrica di ferro, per catalizzare la presenza di idrogeno atomico invece che molecolare." "the powder mix, when used with metallic cathodes, can contain *catalyzing* micrometric iron powder, to catalyze atomic hydrogen instead of molecular" mic Il 24 aprile 2012 16:35, Daniel Rocha <danieldi...@gmail.com> ha scritto: > Does that use H or D? > > > 2012/4/24 Jed Rothwell <jedrothw...@gmail.com> >> >> Robert Lynn <robert.gulliver.l...@gmail.com> wrote: >> >>> >>> They are thus probably generating 100's or Watts output based on their >>> COP=4 claim, so it should be easy to do accurate calorimetry on. >> >> >> As far as I know, you cannot make a glow discharge appear with 10s or >> hundreds of watts. >> >> The calorimetry was challenging in the glow discharge experiments done by >> Ohmori and Mizuno, because both the input and the anomalous power fluctuate >> violently.
