This must be noted that these estimations are when temperature was ca. 118 °C or 90 kPa overpressure. After that temperature rose to 133°C and overpressure to 170 kPa. Therefore 60-80% of water was evaporated and E-Cat did work exactly as it should work. Actually I am somewhat puzzled that indeed E-Cat is working such a perfect way that Rossi can push output power so close to the maximum of the enthalpy absorption ability of cooling water. This is either sure sign that technology is very commercially mature or it is a hoax. It is no more just a lab prototype, but commercially ready prototype. > I was glad to see that he DOES have a simple water trap in the outlet hose, > which separates the fluid water. > I wonder if there is now enough evidence for the "steam quality" people to see that even after such high pressure difference hot water and steam are clearly separated. I wonder how history will remember this steam quality chapter, when prominent people (such as Krivit and Ekström) were violently discussing about steam quality without knowing what steam quality actually means. > When Rossi opens the outlet the pressure of the water and steam is clearly > greater than atmospheric.

And of course for steam backpressure, the tightest place is what counts most. The diameter of the orifice is considerably less than the inner diameter of the hose. I would estimate it to be 5-10 mm. This should be consistent with ca. 1.0°C / 3.2 kPa overpressure and the steam volume that was produced ca. 2 kW total power. –Jouni
