Elections merely facilitate the transfer the power, like (the non-leading edges of?) a drive shaft or cogs.

Even with DC you need a loop (well, a difference).

Carbon fuel one-use mentality where you burn your supply (chemically stored energy) doesn't apply, tho non-rechargeable batteries make it seem so.

It’s even crazier than that. It’s not even the electrons at the “leading edge” it’s the EM field they create even separate the of the wires that actually contain the electrons.

And the follow-up with a physical experiment after the first video started a huge drama.

God I hate that video, he explains everything so badly to the point of completely misinforming viewers. He's talking about a special situation of AC current, but uses DC in the thought experiment. He makes it seem as if the field travels to the load in a direct path and the wires don't matter. No, the EM field is completely based on the wire.

No, the leading edge of the mechanical transfer of power - I was trying to make a faux comparison that electrons would be the inside of the shaft/cog & the fields the leading edges (that transfer the power & are moving more).

I mangled the comparison, should have given up on it. Vibes are hard to compare with anything non-vibes.

Great youtubing in the links, that's how you get them views (benefit several creators and spread science)!
(*I just skimmed them for the general vibe, I'm not voicing support in case they are weird ppl, I don't know them.)

Edit: while speeding through I noticed a very cool simulation (software), yt/mcez0ri9yPY, these are very neat visuals.

non-rechargeable batteries

Yeah, why are they still a thing? Recharchables have all the advantages but more.

Low self discharge. Good for ultra low power devices like remote controls or lights only used on occasion where a rechargeable battery would self discharge faster than the rate of actual use.

Ah right, i forgot about that.

Let's hope those paper batteries by Flint (shown at CES) aren't bs marketing (that they truly aren't harmful as waste & are comparable to normal batteries).
