Regarding the idea with what mentioned in this post with storing each electron is not exactly the same as something like a capacitor or battery. The idea is can perhaps store each individual electron inside of a container not attached to an atom. I guess an electron not attached to something like an atom are as a free electron. Compared to something like a capacitor or battery that have a solid perhaps conductive material which store each electron inside of, maybe like with each electrode of a capacitor. Which maybe this can store more electrons than something like a capacitor or battery of relative size.
Also regarding with each electron is perhaps since an electron does not stop moving maybe like with zero point energy then perhaps can be used to generate energy maybe for example like from each electron’s electromagnetism. Also listed other possible ways could generate energy in this post.
With storing light perhaps higher spectrum of light are more difficult to store in a container than maybe a lower spectrum of light like the radio wave spectrum of light. So maybe it can be done to at least effectively store the radio wave spectrum of light.
