I'm sure this has been done to death in high-school and college physics classrooms and labs around the world, and I'm showing my naivete by bringing it up again. But it strikes me that we're set up to use our electric potential very inefficiently.
To look at it one way, you could say that electrons flow from the ground into our houses, through our appliances and down the wire to whatever utility generates electrical potential for us. What bothers me is the perception that a stream of electrons will generally flow through only one appliance of mine on the way from ground to utility.
Many of my appliances have no need for the full potential available on the wire. Shouldn't there be some way to reuse the available current?
What I'm imagining is some kind of master router that would replace my circuit-breaker box. Rather than the hard-wired (literally) division of current between the various circuits in my house, this master router would manage the provision of potential among the various circuits, taking what comes back down the black wire and augmenting it to provided the needed current for the next circuit.
At its simplest, I think this would be like wiring lamps in series, instead of having all the circuits of my house wired essentially in parallel. And I'm not remembering if wiring in series would make the electric meter spin any more slowly.
If you could do this, would there be any reduction in my demands on the power company? Would it help if you could do something similar at each electric socket or switch?
