The control panel consumes electric energy (that a potential difference and a current) and for what I've learned at school, a fraction of voltage drops when it hit's a resistance and is transformed to heat. That's why you have to add some cooling device to e.g. power supply units or CPU's.
To spread the heat to another medium, air or some liquid, to "put it away" from your prescious device.
And now Dott. Rossie is able to recover this COMPLETY?! Turn heat 100% to WHAT?!Can somebody please enlighten me?
IMO, he is forewarning us that unless we ignore the controllers "consume", the demo will show only a COP1. And it is OK to ignore, because he can "completely recover" it's consumption as usable heat. If we accept that, the demo will show a positive COP. This is nothing new, as he said the same thing after the QX demo, when too many people kept asking how much power the controller consumed. That got them off his back, and he learned from that...which is why we see it again.
Now you ask, *how* he will recover that heat, and put it to good use? I am sure if anyone asks him, he will say he has invented something that will do the job. Just like he invented that very large controller....that just so happens to be about the weight of a big battery, and the alloys that do not melt at 20,000C.
