ok fair enough :P but still yea it's the metal of choice for conductivity.

Just out of intrest, what out-conducts it and at what temprature? I assume it's something to do with "super conductors" ?

Super conductors are conducting compounds that have zero electrical resistance and no internal magentic field. A few have been found, and in the 80s the critical temperature was around 92 Kelvin (-181 Celcius).

EDIT: apparently the highest critical temperature is 138 K (-135 C), which is a thallium-doped, mercuric-cuprate comprised of the elements Mercury, Thallium, Barium, Calcium, Copper and Oxygen.

Still a long way to go, and I doubt we will ever have a room temperature conductor with zero resistance, but it's a nice thought.

A Super conductor at room temparature

With zero resistance!

Only zero resistance if you discount the air resistance of his baton flying through the air... It's tiny enough to be ignored anyway
