Or don’t and drive gasoline power cars and save the energy loss converting gasoline to electricity, and the 1% per day energy loss that evs have if you just leave them be. Or maybe let’s just make hybrids and not lug around 2 tons of batteries. Let’s make a gasoline powered micro energy grid for ev powered cars. The whole ev craze is wildly stupid, inefficient and worse for the environment. Your double AA battery powered toy with an iPad isn’t going to save to world.

it's actually totally feasible to convert gas to electricity and use it to power an EV and lose less energy than just putting the gas into an ICE. Car engines have to be designed to minimize weight and volume to fit in a car. a ground based generator can be significantly more efficient than a car engine.

  Easier to capture the CO2, and reduce other pollutants, too.

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...

  Seems unlikely outside of niches just because the efficiency of gas is awful, even though the energy and power density is good.

  From 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.

I hate having to waste time a couple times a month driving to a gas station to pour stinky stink juice into my wife's car. It's filthy, smelly, and a huge waste of time. I much prefer plugging my car in in my driveway (I'm lucky to have a driveway; lots of car owners don't) and I basically never think about fueling my car or range. My car charges on a 20a / 240v circuit (IE a totally normal one that didn't require a huge amount of effort or expense to install). As an added bonus, my car's more pleasant to drive, quieter, and costs way less per mile driven.
