Assuming the eCat is not a scam:
The Defkalion press conference video indeed says that the eCat power is limited
by pressure.
We know that the reaction chamber is controlled by - quantity of nickel powder,
presence of hydrogen, and requires a sufficient heat to "ignite" the reaction.
Saying that pressure is the deciding factor, I can only assume that this is
pressure of the hydrogen at operating temperatures. Rossi's patent application
states that Hydrogen pressure should be 2-20 bars, and ignition temperature
will be 150-500C.
Assuming that we carry through using the experimental figures, Hydrogen was
introduced at 4 atmospheres (101.325 kpa). With a room temperature of approx
30C (303.15 kelvin), we can estimate final pressure using Gay-Lussac's Law.
Worst case scenario of 500C (773.15 kelvin) chamber temperature at peak
operation, pressure rapidly rises to 150 psi.
If higher hydrogen pressures or higher temperatures are necessary to produce
higher-powered eCats, the simple stainless-steel cylinders currently in use may
be apt to fail.
I hadn't considered reactor pressure, and I thought that I'd chime in with some
food-for-thought.
It's great to hear that a real R&D contract has actually been confirmed with
UNIBO, and now we can just ponder and wait.
