I don't know enough about this and despite having the Internet, I'm
going to charge forward in ignorance. I presume one can hook charging
stations up to already existing electrical infrastructure, such as in
current servos and elsewhere. So wouldn't the need for diesel powered
ones be limited? I mean let's say you have a Telsa and you live in the
middle of nowhere, but let's say the middle of nowhere is still on the
electric power grid. Mayvbe the middle of where has a servo on the
grid. It still pumps fossil fuels into regular cars, but it's also go
the electric to hook up a charging station to. Why can the charging
kit (maybe a mobile one rolled out temporarily?) simply be hooked up
to said grid in the middle of nowhere?

Yeah, I can imagine there might still be some gain from running it at
a constant load... But then do you need to run it when no one's
charging?

That's a good idea.

What about diesels used for other things -- transport or whatever? Is
the extra load of charging (presumably power a dynamo) drawing so much
power away from the diesel that it can't still efficiently do other
work?

Yeah, it's probably transitional.
