> Just to meet business-as-usual trends, 115% more copper must be mined in the next 30 years than has been mined historically until now. To electrify the global vehicle fleet requires bringing into production 55% more new mines than would otherwise be needed. On the other hand, hybrid electric vehicle manufacture would require negligible extra copper mining.
Presumably that's because the reference EV model(s) contain more copper than the reference hybrid model(s)?
Which automotive designers have yet designed with copper reduction as an optimization objective?
Why can't we build with graphene instead of copper today?
Are there comparable ~nanolithography tools and methods for building computer chips out of graphene?
Can power cables be made from graphene?

>> Point2’s E-Tube provides a low-cost, low-loss broadband dielectric waveguide solution that could serve as an advanced alternative to existing electrical and optical interconnects in high-speed, short-reach communication links. It’s 80% lighter and 50% less bulky than copper cables, and could reduce power consumption and the cost of optical cables by 50%, with picosecond latencies that are three orders of magnitude better
