NyTeknik maintains that the liquid mass is at most 10% (steam quality at least 90%) and because of this there is no significant error in measuring the heat output using the steam.


That's based on a steam expert, apparently, who has probably never seen, in his entire career, a "boiler" that is designed so that feed water spills out. So he doesn't consider the possibility.


This is your hypothesis. Experts in steam have considered this possibility, and they say you cannot be right. Storms -- who is admittedly not an expert but still very smart -- also thinks you are wrong, for the reasons he spelled out. The gist of it is that no steam would emerge from the hose, which would be full water moving so slowly that by the time it reached the exit the steam would all be condensed.

That's preposterous. Consider what happens in the E-Cat. It starts with 100% water flow. What happens to this as the heating increases? The end point, with enough heat, would be dry steam. But it would take a lot of heat, because boiler steam is always wet. The sources say 5% is normal. So call the end point 5%. What happens before the steam reaches that point.

Consider this: the water in the hose, as the heating increases, becomes hotter and hotter. At some point, steam starts entering the hose, and the water is heated all the way to boiling. That steam is sparged. However, if the steam generation increases, the steam volume increases greatly, and it starts blowing the water out of the hose. Water and steam moving together, that's wet steam!

When the steam flow is well-established, if the water is not all being vaporized, as it rises to the outlet hole, it will be blown out the hole. That process will atomize it.

There is a continuum of water/steam mixture, all the way from 0% steam quality to probably about 95%.

Perhaps you are right, but I think it is bad form to assert an hypothesis as if it were a settled fact. I do not think we have enough information to rule this out completely, but it is certainly not ruled in for sure, and experts disagree.

I haven't claimed that anything is ruled in. Indeed, what I've been claiming is that steam quality has not been measured. Period. Overflow water, to be expected from the nature of the setup, has not been measured.

With some tests of the eCat we can rule this out. It seems unlikely to me that it works in some tests but not others.

When we don't have prior experience, we have no basis for prediction.
