I should think most house-scale batteries are twinned to a 230V invertor, so
then you just charge the car with a granny lead, ok so a bit more loss, though
finding a battery system that takes in PV panel voltages and gives out rapid
charger car voltages might be a long frustrating search ...

Jerry cans hold five gallons.

A better idea would be to mount windmills on the car roof. There's
always a lot of air going past when you drive fast.

Many short journeys are by motorway, and people do get stuck. It seems
to happen quite a lot round here. A lot of people commute into Sheffield
via Parkway/M1/M18 and in my personal experience they can get stuck.

It's 14 miles from my village to Sheff centre. That's quite a reasonable
commute, and lots do it, using the Parkway/M1/M18 route.

So by definition they shouldn't be getting stuck in the snow miles from
anywhere.

The sort of 'can' (of plastic) you can buy in filling station forecourts
holds 1 gallon.

A better idea still would be to put you on the car roof, and drive it by
jet propulsion from all that hot air ...

Jerry cans come in all sorts of different sizes, I have both 10 litre
and 20 litre ones. I think 20 litre ones are the commonest and that's
not five gallons, it's somewhat less.

I'm pretty sure it's illegal to carry that much petrol in cans in a
car, I think the maximum is two 5 litre cans. It's OK for diesel
though.

real "Jerry" cans would have their contents measureed in litres.

I think that limit only applies to plastic cans. Metal cans can be bigger.

Ah, yes, you can carry up to 20 litres in metal cans (usually just one
20l jerry can then).

Somebody tried that in the 70s to charge up batteries and was prosecuted
for having a dangerous vehicle. "But I was doing it to save energy!" (We
didn't have to save the planet in those days.)

Jerry cans (which is what you mentioned) hold five gallons. They fit nicely in the boot.

Getting stuck in the snow means you're stuck in the snow. You can't walk far. It can be dangerous to set off. I'm speaking from eperience.

Do you mean my farts? If so lighting them might add a bit of thrust.

**Some** jerry cans hold 20 litres, which is somewhat less than 5
gallons. Not all jerry cans hold that much.

It can be even more dangerous to stay put - cars or, even worse,
lorries running into the back of yours, if you're in a conventional car,
gassing yourself by keeping the engine running to keep warm, exposure
and frostbite. Much better to find proper shelter if you can.

No, *you* mentioned jerry cans first of all, I've only ever had a spare
gallon in a car.

What are "Americans" and "Blitz cans" - "Container, liquid, 5-gallon,
Specification No. TAC ES-No, 772B"?

Not sure which is which but I have a table of standard POL containers.

There is

US 5 Gal. Can Gas

Imp. 4.5 Gal. Can Gas
(5.4 U.s Gals)

It shows all the dimensions as well as various other POL containers.

They were shipped over in kit form and assembled in a factory built in
the UK. Located on the spot where there was once a lake. The lake was
filled with rubble from bombed buildings to make this (unreadable.)

Seems to be Magnatex Ltd, Harlington, Middlesex

Plus the amount left in the car's tank may be up to 2 gallons between
the empty light and the engine cutting out. My car's tank is specified
as 55 litres and the only time I've driven 30 miles on the tank empty
light it took 45 litres to fill up again. Not that I would recommend
taking the tank so low.
