Daniel spoke about electricity and flow, not if what is not used in the flow through an electric motor can be put back into the flow through an electric motor without being disregarded because a whole new flow has to go through an electric motor...and to keep the flow of recycled electricity is to introduce just a little more to the flow.
No-one has answered that question actually...folk instead like to debate what electricity and electrons are..even you still stay away from the query of the OP and stick with electrons.
Someone made a comment about being educated about things but what can that education be used for...well, apparently, it is to stick with what they know but not to apply that toward potential of use besides debating what they know. If you know about physics, can you invent something with your knowledge, or just talk about your knowledge without actually applying it to something? Sure, you may understand things, but what does understanding do if it isn't used toward new things?...Just stick with the old?...Go round in circles because old works best?...
Oh well...your kitchen is probably filled with an old wood stove, pump-handle water supply, earthernware crockery, and simple pots and pans. Mine has a refrigerator, microwave oven, non-stick cookware and modern plumbing. Someone invented these things and improved upon them up until the time I bought them...more improvements have been made since then...I wonder what improvements can be made about recycling electricity so we don't waste what leaves our home as we have already paid for it.
Like a car that pipes its exhaust through an apparatus so all unused fuel is extracted and put back through the motor instead of flushed out the exhaust pipe...or a scuba apparatus that pipes exhaled breath through an apparatus to extract all unused oxygen so it can be put back through the system and a diver stays down longer. Can you believe someone actually took an existing thing and re-engineered it to get the most out of a fuel-source?
Now then...what was that original question I asked, and improved upon throughout this little topic, had to improve upon because folk like to debate what the fuel is? Oh, that's right...it is harder to understand than what an electron is lol
So...I have a three-legged horse we can use to play dominoes with, but we have to agree on what colour it is before we start. We already have the toothpicks, made of wood mind you...and yes, at any moment I can change the venue from river low to mountain high, all depending on the weather and if the sun will be in your eyes or mine. Horse should be chocolate if it isn't moving! Pinto if wandering about!
