That’s stupid. Of course running ONE electric pump to fill 100 cars with gasoline is WAY more efficient.
It’s an expedient measure taken in an emergency. Can you plug a car with a gasoline engine into a solar array and have a full tank of gas in a day or two? Is there any other source of fuel for a gasoline engine car, other than that gas station? There are upsides and downsides to both. I suggest you read my exchange with FReeper snoringbear on this thread to see what might not have been covered because it doesn’t need to be rehashed.
