can push charge into a battery rather quickly, so why do you need the
complex logistics of battery swapping?
That's my take; with a 250 mile range my daughter's EV has never been on
a fast charger, only charged at home and a couple of top ups overnight
on my 13A three pin extension. If she ever wanted to do a long journey
she can borrow my car.
Because she has access to home charging, that works.
Without offstreet parking, you need to do regular fillups, even fast
chargers or at work/etc. However if you don't have parking at home you're
already constrained, and maybe a future solution to that wouldn't be
onstreet parking but parking at a multi-storey around the corner which can
also charge. You might have to walk a few minutes to pick up your car (or
summon it, if self-driving finally becomes a thing), but the streets stop
being choked with parked cars.
Or you simply don't own a car but use one when needed. Pre-pandemic, the
car-club model worked for some people.

vehicles making hydrogen fuel cell commercials look more competitive
over the next year or so.
I liken ICEs v EVs to hard drives v SSDs. Hard drives are amazing
mechanical things that manage to fly a piece of metal nanometres above
another piece of metal, and yet be robust against vibration, temperature,
etc. But it's much easier to just have a solid-state chip that does the
storage - no moving parts, no mechanical tolerances, just a standardised
silicon production line. Simple wins.
Post by AJHThe big concern is if China pulls out of the 3 (or 4) nuclear power
plants because of cost escalation in the face of additional planned
windpower what is going to provide our baseload?
I think we need to adjust from an 'Economy 7' world, where there's loads of
cheap coal-fired and nuclear power available overnight, so one where
more power comes in the middle of the day due to solar, and charging things
is more opportunistic based on conditions. EVs are perhaps better suited
to this than other consumers. The 'baseload' is then quick-response power
stations for covering for the gaps where there isn't enough sun/wind/etc to meet
demand. Today that's gas, maybe batteries or other storage will fill that
gap.
