UK petrol pumps push out 50 litres per minute which means that most people spend less than a minute at the pump actually pumping fuel. Obviously it takes longer once you add all the other things you have to do.
1 litre of petrol is equivalent to 10kWh. So that means the petrol pump is equivalent to a 30MW supply. That is the same capacity as 10,000 UK domestic 13A plugs. That plug requires a conductor size of 1.25mm². Multiply that by 10,000 and do the maths to get diameter, you need a cable of 12.6cm thickness to carry that amount of current. Or, you will need a much higher voltage with a corresponding increase in insulation thickness.
Does this sound in any way feasible?
