I have just finished an initial thermal analysis of the Hotcat, using Spice, in an attempt to explain its unusual "sine-like" output. http://lenr.qumbu.com/rossi_hotcat_may2003_spice_130605.php I tried various possible "waveforms" for the hotcat's excess heat, and found the best fit to be a "sawtooth" -- starting when the heater pulse arrives, finishing at its peak, and then falling rapidly. I am working on a model to explain this behavior. On vortex David Roberson is exploring the control mechanism, also through a Spice model. He argues for a linear control model. My short answer is that yes, Virginia ... a small heat source CAN control the large heat source.
