No, what Joshua said does not even resemble physics. If his explanation would be even remotely truthful, kettle boilers would be impossible, because all water would escape from tea pots as low quality steam when water starts boiling. That is because cutting forces that form low quality steam are several orders of magnitude stronger in tea pot than in ecat. Therefore it is impossible that ecat would produce less quality steam than 99-98%, because low quality steam cannot be produced in low pressures and it cannot exist in closed container where velocity is not ultra high (pressure difference counted in megapascals). Therefore also Galantini's and Kullander's attempt to measure steam quality was silly, because we knew a priori that steam quality was ca. 98.8%. But of course steam quality does not tell us anything how much steam was formed and how much water was overflown and percolated as hot water. —Jouni Ps. What Joshua is mixing that he does not understand that hot water is not 0% quality steam, but it is, well, hot water.
