Sub 200 mile trips account for probably 95% of al domestic motoring and

200 miles is a very large threshold. I'd use 50 miles as where "long
distance" starts.

Which, going by the battery-to-mileage efficiency of the Pious would
require 75kWh of capacity.

There's also the problem of people not necessarily having access to
charging sockets at either home _or_ work currently, which would require
a LOT of infrastructure upgrades in order to be provided.


Domestically its a twelve hour charge overnight on cheap rate. Easy
enough for those with garages and well within domestic supply limits.

For regulated car parking, again easy enough to add socket-in-pole
charging meters.

Hardest one is on street unregualated parking. Poeple will have to find
sopmewhere else to park their cars overnight. Oh dear. What a shame.


And where's all this extra electricity coming from, anyway?


About 70 nuclear power stations by my reckoning, and a 3:1 upsize in the
the grid overall. Howver tht would happen over a couple of decades
progressively.


London ALONE sees 33bn vehicle km per year. That's about 15bn kWh of
electrickery at Pious battery-mode usage rates. 15 terawatt-hours.

Now, remind me why I was meant to be changing from 60w incandescent light
bulbs to 11w CFL?

For purely political reasons. We need to be using more electricity, not
less, as long as its nuclear and not fossil generated. Anyway, off peak
its cheaper than oil, now.
