Yes but a typical modern internal combustion engine only uses gasoline about
20% efficiently so really you are only getting 8 kWh out of your gallon of gas.
The rest is just wasted as heat which is a shame since 32 kWh is a lot of
energy. But at least homeless people can stay warm during the winter by camping
near freeways.
