Battery Idea – Set Of Probable Inventions

I got ill yesterday. Looking at the paper roll I wondered. Is there a fast path to needed inventions?

A paper roll has layers like a battery but a battery has no hole in the middle. So the idea is to see if a hole in middle of battery type could be taken advantage of. I mean its not a geometrical difficult solution.

It belongs to the set of probable modifications. Then could a Rotating Magnetic Field in the hole deflect out the ions? To increase the efficiency of the battery.

Inner hole. Less Noise since a light bulb thread lights up with energy losses
