I don't see how boiling a pot of water and sticking a thermometer somewhere
into the swirling flow can possibly be as accurate as calculating it. Depending
on the heat source, the pot and the placement of the thermometer you should
always find a range of temperatures at least one or two degrees C wide. If it
was pure water, then the 99.6 C measurement is just a confirmation for that
(unless the pressure sensors of the Italian meteorological society areĀ
significantly less accurate than the thermocouples used by Mats - which is not
imossible, of course).
As far as the unaccounted for water is concerned: I found before/after weights
of the hydrogen cylinder in the report but not from the machine itself. So the
missing water is only unaccounted for if we assume that the eCat didn't contain
any more liquid after the test than before - or did I miss the weight and it
has been mentioned somewhere else?
