Most of you have no idea of the energy density problems of batteries. Gasoline has about 100x's more energy density than LI batteries.
Electric cars are fine around town but they will NEVER have the energy density of gasoline.
Density is similar if you were required to carry the reactant along with you in the gasoline vehicle. But since the air (oxygen) is brought in as you drive, the gasoline vehicle has that advantage. For every 1 pound of gasoline you burn 14.7 pounds of air. So a 20 gallon tank processes over 1700 pounds of air. A bit less if you had a tank of pure oxygen but you get the idea.
The hard part is converting that CO2 back to O2 & C as nature is not able to keep up with the amount we burn. This is the part that is most often forgotten and scientists are saying is a cause for warming the planet.
