You can make the power into the load fairly constant as the load changes impedance if you place a series resistor in the path who's value is equal to the wire resistance. Of course you will be throwing away an amount of power that is equal to that taken by the load.
This is a crude form of impedance matching. A voltage source needs to drive the combination.

The behavior of the power supplied to the core heater is interesting. A constant power circuit might best be used to minimize the power fluctuations supplied to the reactor heater so that the temperature of the heater stays constant and predictable and most important adjustable. The details of such circuits can be found on the internet but what might be easiest to do is use a battery charger of appropriate amperage output to power the heater and a fast response time constant current regulator A large laptop charger of a car battery charger might work paired with a constant power regulator of sufficient power rating.. Here is a YouTube that looks applicable which might save the cost of an expensive lab power supply. https://www.youtube.com/watch?v=OSO70Y_TxYQ I am not at all competent in the details in this area, so advice in this area would be appreciated. ---------------------------------- The TPR2 testers did not report rapid temperature fluctuations so Rossi might have implemented a constant power supply function in his control box.
