That is pure nonsense.


Petrol is around 34MJ per litre. A 50 litre refuel takes around 2
minutes

So that is 1700MJ transferred in 2 minutes

1MJ = 0.28 kWh

Or around 476kWh of energy transferred from the petrol station storage
tank to
the car fuel tank in 2 minutes

But 80% of the energy in that tank is wasted. So go back and do some sums.


Why don't you give us some realistic realisable sums instead?..
