I guess they want to remove completely any possible source of error or
ambiguity which steam brings, in a way or another, if the source
reporting this information is to be trusted (it should. At the very
least, Daniele Passerini confirmed that some kind of test is going to
start on September 3rd).
If the steam hose is thermally isolated and short, then I dont see how
this could introduce much error.
If the steam is finally condensed or dissolved into a water bath then
the heat transfer should be almost 100%.
If more accuracy is necessary then they shoud calibrate the system,
using a known heat-energy source.
I dont see any necessity for an accuracy of more than 30% to do a
scientific proof of concept.
There is too much risk in changing a working system.
It is always said, that the ecat is still difficult to control and
therefore they should minimize the changes to the system.
