@TheWarOnCars I teach science to 14 year olds. The other day we were talking about energy and efficiency of engines. I posed a question - imagine you are buying a new car and know that some of the energy from fuel is converted into heat. If you are to spend 100€ a month on gas, what is the maximum amount you are willing to accept that your car will convert into heat losses. Most said around 30€. When they learned that 70€ is lost one kid said - that’s a robbery!
@ProfT @TheWarOnCars oh, that kid is gonna be pissed when they find out how much of the remaining fuel goes into moving the passenger compared with moving the car.
