Here in the first image inside the yellow, we can seea circuit formed inside a crystal with a cubic structure.
The image is taken from The Alchemical Manual.
In the other 2 images, you can see a standard full-bridge rectifier, which I'm using with shotkey diodes to rectify the high-frequency AC into DC current.
It looks like Nature has all the answers if we know where to look:
The question is, what applications can have the other circuit on top of them?
