Replicating a system is valuable. It forces one to evaluate every detail of the design of the system. They say that the devil is in the details. In this light, the HOT cat as tested recently is not yet a completely designed stand alone system.
First off, the Hot Cat is hard to start up and if not manually controlled and constantly monitored it could possibly explode due to a pressure excursion. The start up procedure is long and complicated. The Hot cat cannot be easily cycled on and off. True, all these system faults could be remedied using a microprocessor controlled automation system using temperature and pressure core readings as variables in a feedback loop.. But such a system would require input of both the temperature and the pressure. The temperature control is provided but the pressure feed back is not yet available. It looks like this pressure feedback is not yet covered in the structural design of the Hot Cat. This is a deep design problem. There is no pressure transducer provisions made at present in the structural design of the core tube. The programming of a microprocessor based controller for the Hot Cat will not be easy. Beside the pressure and temperature considerations, there is the superconducting behavior that was seen in the TPR2 test that might be manifest in a functional LENR system. This behavior might well be seen in the power feed to primary core heater. This behavior will throw a complication into the computer control algorithms. My estimation is that the Hot Cat has a very long design road ahead of it.
