Couple that with a 60% CCGT power statin and you have around 50%
gas-to-wheel which is better than any IC engine will achieve.

Indeed - but given the lack of energy density of the best batteries,
still well short of liquid fuels.

You obviously have not heard of supercapacitors.

You obviously have a short memory. I mentioned that they have even lower
energy densities than batteries.

They claw back most of
the kinetic energy and give it off to accelerate.

That they are well suited to. But not the bulk storage of energy in the
first place.

Shanghai is using
them now to run EV buses.

Which is irrelevant unless you want a car than needs a charge every 120
seconds.
