And I suppose the goo tank, theoretically, could be simultaneously emptied back into the filling station reservoir so that the used goo could be recharged?

Could work.

Or, how about a system that swaps out more solid pre-charged batteries?

The latter could be vulnerable to some problems, though. Swap junk batteries for good.

It sounded interesting.

Regular or premium goo?

Doing a battery swap isn’t efficient because the number, because even if you could quickly do a swap, the number of batteries needed to service the average number of customers a day would fill a large warehouse.

Would be OK if you just leased the batteries, a bit like the propane tanks from your hardware store - turn an old one in and get a new one...

This is already available in Japan. I believe they might be testing it in SF and possibly NY too.

Batteries degrade. They charge less, as they age.
