Actually, I'd like to be able to generate *all* my electricity from
gas - not just in an emergency. Bearing in mind that the marginal
cost per kWHr of (on peak) electricity is 3.6 times that of gas, I
would save on fuel costs as long as the overall conversion
efficiency was more than about 27.5% --

Not as simple as it sounds :-)

You have to add in the cost of the equipment.

Much the same kind of sums as:

(a) converting a vehicle to LPG
(b) trading in a huge gas guzzler for a super efficient micro car

For (a) the payback is generally at least 20,000 miles. Given that,
the payback for (b) will probably be even further away, assuming you
spend more than £1200 on changing the car.

So our VW camper is still petrol and we still have the Volvo Turbo
Estate :-)

However I would be interested to see a costed example :-))

Yes, I know that the overall economics probably wouldn't be favourable. It
just irks me that I spend more on electricity than gas, despite only using a
third as much of the stuff!
