copper to get it, perhaps inadvertently from the copper-alloy plumbing. But
that is a guess.
If Rossi's magic powder works as Celani's treated ISOTAN44 wires
(positive feedback with temperature), there's little reason to doubt
that his gain could be higher. Just increase the amount of active
material and you can immediately have useful amounts of energy, although
this might be expensive and/or impractical. In fact, I think this is
exactly what Rossi did in is earlier public tests to scale up the effect.
Celani, with 70 W/g (data by Daniel Rocha), would just need 150g of
active material to reach about 10 kW of low temperature excess heat and
a quite high COP, if he wanted (he would need a proper reactor vessel
first, however). Incidentally this is about the same amount of material
reportedly used by Rossi in his early 2011 demos. I guess it would be
relatively expensive to set up such a demonstrative reactor for Celani,
but it's not undoable, although it would be scientifically useless.
70 W/g is a low starting point as a specific power for the active
material too. I imagine this could be vastly improved with funds and
good engineering. According to "Cures" (Domenico Fioravanti - the
colonel engineer who tested Rossi's half-megawatt plant in October 2011
and used to post anonymously on a public forum, if you trust him),
calculated the specific power for Rossi's powder to range between
480-3300 W/g [1] - so apparently there's plenty of room for improvement.
Combine this with cheap scaling up methods (add more material) and you
can see why Rossi might be worried about competition, especially Celani's.
Cheers,
S.A.
