What we really need is to dump the idea of batteries, and work on a more
efficient heat engine or fuel cell for the primary power.

Electrical transmission is fine as it stands but the electrical to
chemical conversion and back again is not the real long term answer to
this problem.

Its not anywhere there as yet but given sufficient time.

Some sort of inductive power transmission from vehicle to car might
allow a better system involving batteries as the power to drive the car
is from external means, and then the battery can go "off grid" for the
bits of road that aren't so equipped.....

Car with a built in nuke genset?

Now you are talking..
