In my head, the future history of car like transportation will be something like: horse, gas, battery, gas. The second phase being "fully green" gasoline — perhaps via air reclamation?
Obviously, the real long-play would be a cyberhorse on the far side, somehow...

- adgjlsfhk1 4y agoFrom an energy perspective, gas is a pretty terrible battery. It's 25% efficient for a car to discharge, and currently very inefficient to synthesize. EVs on the other hand are over 90% efficient for charging and discharging. Gas is energy dense, but it's hard to imagine quadrupling vehicle energy consumption being a good idea. For uses like airplanes and trans-oceanic boats, carbon captured gas might be the best zero emissions option, but for anything where a battery works, you would never go back to gas.
