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.

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.
