Has anyone read about these?
A capacitor can be used as a battery for a very small amount of energy. The energy stored in a capacitor is (C*V^2)/2.
But recent collaborations between mathematicians and electrical engineers have found a way to optimize the internal surface area of a capacitor, giving it a higher capacitance. The dream is to be able to use a fractal capacitor to store portable energy, such as in a car or other portable device.
We've all seen blogs about using capacitor banks to fuel cars, but you have to have an enormously large capacitor bank in the bed of an EV truck to be able to make it work.
By using fractal capacitors, they've been able to increase capacitance by a factor of about 2.3.

It's not much so far, but at least it's interesting.
