No idea whether it actually works but fun all the same:
Despite mind-boggling technological change in almost every part of life over the past 100 years we still transmit electricity and electrical communications over copper wires. Tirupati says it has produced a new substance, a mixture of aluminium and a type of graphite called graphene, that can be used to make wires with superior technical qualities – qualities that will bring benefits such as increasing the capacity of airliners.
Hmm. well, OK. One thing here is that to make graphene you don’t have to start with graphite, although that’s an aid. It’s just carbon and can be made in other ways. Yes, OK, that’s like saying diamond is just carbon but then that’s also true, you can make diamond without the kimberlite and the volcano.
So, aluminium plus carbon beats copper for wiring does it? Ain’t that a fun story about substituitability? And makes some of those worries about running out of metals for the green revolution go away too.
