What is it we really want here? Isn’t it free electricity? Something with substantial volts and amps?

Start by paying attention to the pioneers. The experimenters, scientists and physicists in the past who ‘discovered’ and worked with electricity. There were no laws or definitions or even terminology for it back then. It was more like ‘Hey, I have an idea. Let’s try it and see what happens.’ They invented the terminology to describe volts, amps, and magnetic fields. They didn’t know what it was but they figured out how to work with it and use it using their own terminology.

At it’s most fundamental level we still don’t know what electricity is but we don’t need to know that much detail. We only need to know the basics to get started.

What are the basics, the foundation to build upon?

Definition of a volt.
One volt is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. The pioneers thought of potential difference as tension.

Definition of an amp.
One ampere is equal to 1 coulomb or 6.241509074×10¹⁸ electrons worth of charge moving past a point in one second. So what’s a coulomb?  6.241509074×10¹⁸ electrons.

Those two definitions tell you what needs to be done. You have to bring charges (coulombs/electrons) into the system and raise the tension on those charges to move them past a point in the circuit at the rate required to obtain the amperage you want. Nothing more, nothing less.

Anything that aids that goal is worth investigation. Anything that does not, is noise.




Edit: corrected 1018 to 10¹⁸

...
I will add, when you say volts and amps, how about we use a single term and
say power, ....

The only thing I have against that is it diverts the focus from the two distinct components of electricity, volts and coulombs, and lumps them into a third form. Each component is obtainable separately and it's important not to lose focus on this fact. Power and energy come after volts and coulombs are obtained.

I absolutely agree otherwise. Good input 

Edit: One more point I would like to make. Free electricity does not require self running or over unity. Worthy goals but not requirements.

overunity doesn't exist.
self running exists if mechanism of powering the device even if it's not visible to the naked eye
uses energy conversion from one form to the other.
or we are dealing with energy transfer.

Wesly,
You are absolutely right. OU does not exist because humans cannot create something from nothing.
And that does not mean self running along with a usable electrical output is not possible.
