I think this might be one of my best ideas ever.
Philosophically its possible to heat a little here and a little there. One reason for this is when you don’t have enough energy for boiling the water. You want to maximize the efficiency.
As an example of network boiling is several heater wires that a CPU can control individually with some machine learned algorithm.
So the guess is that you have like a 3D mesh of heater coils that the algorithm can find a good time voltage series for.
