He does not think that a large source of electrical power added to the system needs to be accounted for. * * JR:It is NOT added to the system, for crying out loud. That is physically impossible! Of course it can be! It is potential energy! and potential energy can always be added. * There is no mechanism to add it, since the water is still moving when it emerges from the machine, as fast as it was when it went in. Ever hear of friction. No wonder your so-called calorimeter didn't work This is fundamental Newtonian physics. You cannot convert mechanical action to heat unless you slow down or stop the body in motion. Finally you got something partially right. You can slow it down and convert potential energy into thermal energy. They did NOT measure the velocity of the exit stream and they probably converted some potential energy into thermal energy.
