It's the sum product of knowledge that is difficult.

Where do you get copper? From what ore does it come? What is the smelting process for it if you could find it? … And how do you get the compounds used for that?

Even if infrastructure survives, you need to rebuild the transportation networks and the trade knowledge to perform the tasks in the process pipeline for wire and the like.

We don't even make our own chips or discrete components anymore. So there is that.

There are a lot of things we can make on our own as hobbyists because we can call up the warehouse and order some nickel foam or other such material… But if there's no warehouse and we have to source some of the raw fundamentals….

We can describe how to make greek fire once we have the ingredients we are used to working with - but once the supply chain for those ingredients we consider "raw materials" are gone - the people who come after us to interpret our works can only go off of our descriptions of the stuff we needed but no longer had to make the wonders of today.

I am not sure I understand what you all are trying to do?

Inductors do create an inductive kick. The way I think of it is in terms of current flow. The electrons start at one side and build up a sort of inertia to continue to the other side. It's not a "negative spike" so much as the current flow will attempt to continue regardless of the other voltage sources. It converts current into voltage potential.

You can use a bridge to rectify it. But if you want to harness energy from an inductor you need another magnetic field for it to operate off of.

I theorized the design of a non-ferrous motor and generator that could work purely on induction. Have yet to build a trial, but it's only possible with solid state electronics and active switching.

Yes and no.

The biggest challenge is transportation. Effectively all transportation revolves around oil production and refinement. If that supply chain fails, society becomes isolated and insular. The copper just on the other side of the state suddenly becomes the slow boat from china.

Communication becomes another challenge. Communicating the need for a resource and negotiating an exchange for it. The organizational structures to accomplish all of these….

I'm not saying it can't be done. I am simply saying that the task is absolutely enormous and relies on people elsewhere to do their part to preserve civilization. There is only so much someone like me in the middle of Missouri can do once the oil distribution systems collapse. There are ways. There will be means to achieve various things - but I think many underestimate just how hard some of our achilles heels being damaged will harm us.

Inductance and capacitance are properties of the circuit/components, not the effect of current or voltage.

Of course, we typically think of electricity incorrectly. Current flow is the effect of the electric field, not the cause. A conductor is basically a shunt in the electric field which closes the effective space between two potentials. To be ultra-trippy, as far as an electron is concerned, a wire is like a wormhole…. Not exactly because electrons moving through bulk material is slow, but the movement of electrons is the effect of the shunted electric field, not the cause. The magnetic field is the effect of the movement of electrons.

Which is why AC is more efficient than DC and why inductors and capacitors behave the way they do.

In theory, far greater.

The practice is where things get difficult.

In a purely theoretical world, a perfect insulator could be used to form a dielectric barrier that would not break down. At this point, you could store a theoretically infinite amount of energy in any size capacitor as you just increase the voltage stored to reality-splitting potentials.

In practice, existing silicon carbide rectifiers and IGBTs can work with around 1.2kv in a single stage device (no back-to-back gates or diode arrays). Aluminum nitride offers some of the best resistance and thermal conductivity in one package short of toxic boron nitride. An aluminum nitride dielectric would thus be ideal for a high duty cycle capacitor.

The problem comes in how to then create surface area of the conductor for the capacitor. Graphene is probably our best bet at this. You would then layer graphene and aluminum nitride using molecular beam epitaxy or some related process to create a capacitor with optimal capacitance and a breakdown voltage of around 1.5kv - whatever that translates into for aluminum nitride layers.

There are ways to get higher capacitance using electrolyte polymers and the like, but to my knowledge none of those will hold up under more than about 30v. Wet and dry electrolytes tend to do weird things as voltage increases and will split apart.

To truly begin increasing the power of capacitors you need to look at capacitance as incidental to your lack of voltage.

Energy stored in a capacitor is a multiple of the capacitance but a square of the voltage. That is - double capacitance and you double the stored energy. Double the voltage and you quadruple the energy AND, per how capacitors discharge (RC time constant) you increase the available power to the circuit.

Of course…

On the construction site with a "1.2kv" battery pack, if you do something stupid and somehow touch the contacts, it will not shock you or throw you, it will just make parts of your body disintegrate.
