Swappable battery packs would have to be some standard size and

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.
