Rossi: "Steam Was Superheated" in 1MW Plant Test

The discussion about wet and dry steam is one that goes back a long way in the E-Cat story, and there has been discussion here about the quality of the steam used in the 1-year 1MW E-Cat plant test. The question has come up on the Journal of Nuclear Physics recently with people trying to get more information for Andrea Rossi about some details of the ERV test which as not yet been published.

Rossi has not given much information away, but has given a few clues away. Interestingly, he has said that Fabio Penon (the “ERV”) has discounted some energy in his COP calculation to be conservative. Here are some Q&As from the JONP.

“You told Mats Lewan that to be conservative, the ERV ignored the energy corresponding to heating the inflowing cooled water (at about 60˚C) to boiling temperature.

“Did the ERV also ignore the energy corresponding to heating the vaporized water to temperatures above boiling point?”

Good question. Yes, the ERV ignored also the energy spent to heat the steam above the boiling point, as well as the energy necessary to raise the temperature of the water from circa 60-70 °C to the boiling point, to be conservative.
Warm Regards,

“About your answer to Sebastian:

“Does this imply that heating was done in stages?
I mean one core was boiling water and the next was superheating the steam from boiler section?”

Oystein Lande:
It’s ok, thanks for your comprehension.
The circuit was complex, but yes, the steam was superheated.
Warm Regards,

If the steam was superheated, as far as I understand things it would be dry, and the temperature would be likely be some degrees higher than the boiling point. I will, however defer to readers here with more knowledge on the subject for more analysis.
