At least it dosn't need air conditioning.

Car power, worst to best, roughly:

Rubber bands.
Springs.
Animals (humans included)
Sails.
Compressed gas.
Steam engines.
Solar cells.
Batteries.
Electric trolleys.
Cable cars.
Funiculars.
Fuel cells.
Gasoline turbines.
Coal dust turbines.
Hydrogen turbines.
Gasoline piston engines.

Did I miss any?

The battery thing may have peaked. Manufacturers are leasing underused
parking lots and airports to store unsold cars.
