The conductor with pn structure polarized at casting is a project.
It is a project that could not be imagined by the electricity of "electric
charges".
A solenoid with such a conductor is a source of electricity.
The maximum density of atoms with oriented polarities
depends on the section, on the polarizing intensity on casting and the pn
alloys.
The device is simple to make, and the utility would be enormous.
It would reduce pollution locally and improve the climate globally.
The project is free but delivery to consumers should also be facilitated.
