[I]n 2011, the University of Technology Sydney made a significant breakthrough by synthesizing something called graphene paper (GP), an ultra thin layer of graphite that has five to six times lower density than steel, but is two times harder with 10 times the tensile strength and 13 times higher bending rigidity.

GP also works well in lithium-ion batteries and even better in lithium-sulfur batteries. The latter kind has far greater storage capacity and is a whole lot cheaper; GP solves the sulfur degradation problem.

There’s a lot more at the link.

Of course there are practical problems yet to be solved at this early stage. A carbon fire burns hot. Get the car, or pickup, too light, and the shock absorbers will need serious redesign—a particular problem for working pickups that do off-road work. But still….

An all-carbon vehicle? Gah. The horror.
