At some dinky rural gas startion and hot dog emporium, a gas truck can
show up every few weeks and reload the tanks. It might not be good
economics to run 20 miles of megwatt power lines.
And the gas truck delivers how many megawatt-hours of energy in its
one load of fuel per \'few weeks\'?
Ballpark 200.
One advantage of gasoline is that it stores energy. An electric
charging station doesn\'t. So the feed line has to support peak load.
The gas truck only has to deliver the average load.
Easily replaceable battery packs would solve that problem but I don\'t
see that happening with the current skateboard chassis designs.
The lithium supply will be further stressed when all cars are electric
and there are two battery packs per car.
Swappable battery packs would have to be some standard size and
interface. Possibly several small packs per car or many per truck.
If batteries were standardised (not gonna happen as Ricky points out)
then you don\'t need to own one, and you definitely don\'t need two for
each car - just a swap&go rental system like BBQ gas cylinder exchange.
But since cars are a vanity item (like clothes and accessories) there\'s
no way to standardise a format that imposes strict dimensional and
structural requirements on the chassis.

The fixed one can never be standardized, but the removable one can. All we need is a common connector. All other features (charging, moving) are still tie to the fixed one.
Ed, only you would not even understand the concept of a swappable battery, thinking there was some utility to only swapping half of your charging capacity, meaning you have to stop twice as often. But for you, that would be a 400% improvement over what you are doing now.
