Why don't you cite a proper textbook about soild state physics, or metals?
Why do you have to rely on googling "SHM"?

So that any one can follow the link - not everyone has access to a library, or wants to.

Electrons are extremely mobile.

Yes, but in a wire the electrons scatters on all sorts of things: what is the average scattering time (picoseconds, maybe?)?
High-Electron-Mobility-Transistors at low temperatures (1 K) have an average scattering time of 100s of picoseconds (10^-10 secs). In those 0.02 secs, an electron has scattered an average of 10^8 (100 milion) times.

This makes it worse. In IG space the electrons do not make any collisions as they oscillate. If electrons in ac can do shm and collide all these times then there is no problem with my theory.

And that scattering shows up as heat - which means for an infinitely old universe and your theory to work, we should be piping hot (incredibly intense microwave background...). Else the energy simply disappears, and conservation of energy does not work in your universe.
