I'd like to see a full development of this idea. Something like a CPU that runs at -3 GHz. Or perhaps it generates power while it undoes computation?

It's too bad node size is a linear dimension rather than area. If it were area, we could get into its many complex/imaginary properties.

Ha well one that does computation with no power draw is theoretically possible, since processing as such does zero actual "work" physics-wise, it's all just various mechanical losses.
