Check this out. Have you heard?
Electrical signals transmitted at high frequencies lose none of their energy when passed through the 'wonder material' graphene, a study led by Plymouth University has shown.

Um... so, yeah.
"Wise men talk because they have something to say fools because they have to say something."
It would be nice if Phys.org were a little more cautious with their hyperbole. There's going to be some expected energy loss, even if it's greatly reduced with graphene - unless this really is some kind of superconductor at room temperature. Laws of thermodynamics, and such. Still, hell of a material, looks promising for the future of electronics.
Just to be clear, superconductors DO have zero resistance but I doubt graphene is a superconductor at room temperature. If it really is, that's AMAZING.

The reduced thermal noise interests me. This could lead to ultra-sensitive radios! It's good news for us ham operators, potentially.
Superconductors are certainly an interesting phenomenon. How this doesn't violate the laws of thermodynamics baffles me.
