Essentially, depending on the thermometer being wet to inform the observer of the lack of water is foolish.
No, it isn't. Galantini knows what he is doing. The probe would be wet because these probes are tapered. The plug that seals it is wider than the probe itself.
Jed, you have reliable information about the flowing water test? How do you know whether he left it alone or not?
I don't know if it is reliable or not, but here is what they told me. It lasted 18-hours, which is most of a day. They did not babysit it the entire time. They went home, leaving a video camera to watch the instruments overnight.

Jed, if you could not see the boiling, how could you judge the level?
By the sound and temperature. I can estimate the water level in my miniature steam engine boiler by similar means. It has a window but when the water level is high or low you cannot see it. An experienced cook can judge the water level in a pot by sound, for example with a pot of vegetables being steamed, with just a little water at the bottom.
Granted, this is a complicated way of doing things. The Defalion reactors reportedly have a primary cooling loop with glycol or some other liquid with a high boiling point. Water going into the secondary loop in the heat exchanger boils.
