Its not special relativity that they account for in gps, its general relativity. As for the whole neutrinos travelling faster than the speed of light, it doesnt mean anything yet until another institution can replicate the results. Hence as soon as the team at the OPERA detector found something anomalous they urged the entire scientific community to check their results and perform the same experiment. In the modern scientific community nothing is accepted until it is replicated. As for the super conductors, recent inovations have allowed super conducting to occur in mercury thallium barium calcium copper oxide (retarded name yes :P) at about 140 kelvin which is still only -160 degrees.]]> generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=off-topic&topic=18869&post=342486 Wed, 19 Oct 2011 15:02:17 +0200 Reply by iceweasel https://staging.etf2l.org/forum/off-topic/topic-18869/page-2/?recent=342486#post=342477 generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=off-topic&topic=18869&post=342477 Wed, 19 Oct 2011 14:45:03 +0200 Reply by Demophon https://staging.etf2l.org/forum/off-topic/topic-18869/page-2/?recent=342486#post=342475 Quoted from dodgydogman

[...] In terms of the physics, thats impossible pretty much. As far as i am aware it is impossible for a material to have both super and semi conducting properties. If you want insanely fast computing, look at quantum computing, everything happens instantly with that :)

[...] Would be cool to have materials which super- and semiconduct at the same time though... Insanely fast computers that generate minimal amounts of heat :P

It's a phenomena known as the Meissner Effect, happens when most conductors are supercooled to a few tens of kelvin (-260 degrees approximately). As for the graphene response, graphene is not a conductor, its a semi conductor. It has some pretty amazing properties, like being totally 1-dimensional and every conduction electron travelling at exactly 1000 km per second, yet super conductivity in it is highly unlikely to occur.
