I speculate that the Ni/H reactor produces massive amounts of RF. I may be that sensors cannot operate inside the reactor.
Furthermore, this may be an opinion not held by many, but I believe that DGT has solved the control problem. This is a fallout of how the two different energy pumping methods work between the two systems. It seems like a simple matter to add a thermostat to the design. The max safe temperature is reached as determined by the thermostat, the pumping power is turned off. In the Rossi system, the heat from the primary heater, interferes with the operation of the thermostat and Rossi must run his reactor blind without feed back. In the DGT reactor control method, the low temperature state is detected by a thermostat and a arc pulse is triggered. All the pumping required to reverse the fall in reactor temperature is delivered in 20 milliseconds. The reactor's temperature begins to rise like a ball hit with a bat. The path of the ball is well defined by the laws of physics and its the temperature rise profile is the same without exception. This is DGT's big advantage. Precise reaction control and safety will in the end make DGT the leader in LENR reactor market share.
