Dear John,
You're right. Once again I became confused by that stupid unit
construction L/100 km!
My note should have read:
Average Boeing 747
34 megajoules per litre (34 MJ/L) for aircraft fuel, and
1 600 litres per 100 kilometres (1 600 L/100 km) fuel consumption, then
an average Boeing 747 consumes 544 000 joules of energy for each metre
it travels (544 000 J/m).
Summary
Car 3 200 J/m
School bus 13 510 J/m
Truck 15 440 J/m
Boeing 747 544 000 J/m
These figures are now easily comparable.
Cheers and thanks for your help,
