I'm just giving the op a survey of what's out there as far as variable capacity pots. I agree with you guys, most of the sub-heavenly priced stuff in the mini and whole home residential range is going to be brushless permanent magnet stuff.
I'm still kinda intrigued about the whole supply matching strategy here. As of now, the proposal seems like a leveraged heat dump to me. The thing that baffles me is how much extra heat can be dumped into the floor? At a certain point, enough should be enough. Then what?
