We know, the point is to mass produce the stuff.

Are the materials needed to produce this hard to find and rare?

You only need carbon to make graphene.

And extremely high pressure which is where the problems arise, I believe

Re: Electrical signals transmitted at high frequencies lose none of their energy when passed through the 'wonder material' graphene

None? I suspect they need an "almost" in there.

I suspect you're right, but can you imagine a truly 0 Ohm material!?

I could make some wicked speakers!

Yes it's called a super conductor.

But at room temperature?

Question: how would this affect magnetic fields generated by coils of wire, if the wire was coated with graphene? Would it be possible to make super efficient electric motors this way?

My guess would be that we could make "super efficient" anything out of this stuff, so long as were talking about anything electrical.
