But how do you heat an electric car? Not much fun using a totally
unheated behicle in the winter. Even keeping the screens clear becomes a
bit of a problem.

Some earlier electric cars had petrol burners to warm the interior. Is
that included in the fuel efficiency claimed?

There is zero insulation in a car. Insulation can be bonded onto the car
panels. Herat can be reclaimed from the electric motor too.

In sunnier climes PV cells can be the whole roof of the car.


But with the super efficent electric motors they use, the 'waste' heat
will be fairly low - and will not devleop until the car has been driven
for a while. So some means is still required for clearing screens and
keeping occupants tolerably comfortable.

Actually, PV cells can be the whole roof of the car in any climes. But
they don't help very much with heating on a dark winter day in the UK.

They don't help much on an even colder night either.
