What are the main obstacle to cheap EV?
Today's car are heavy as hell compared to cars made 30 years ago.
Is it possible to make cars that are build on a much lighter base, but that use a heavier/cheaper battery (sodium based?)
- asdff 4y agoYeah, its called an ebike. When you are using a vehicle as large as an electric car to run your errands, probably 95% of the energy is spent just to move the vehicle around, not you or your groceries but just the vehicle to A and B. With a 50 lb ebike and a few panniers running those groceries versus a 5000lb ev, you are doing the same work but a lot more of the energy spent is going to the actual work, moving you and your groceries, rather than the vehicle. Now if you consider the length of it, things aren't any better. The next time you are in gridlocked traffic, look at the cars around you. Imagine the cars just disappeared and everyone was standing in the road. It's obviously pretty inefficient to wait in line with 20-30 foot gaps between the person in front of you and 10-15 foot gaps with the person beside you, but thats what rush hour is in cars.

- asdff 4y agoI'd imagine an e rickshaw would eliminate the need for a pickup truck or an SUV for most people. Get one with a back that can open like a ute and you can haul anything.
- d--b 4y agoI live in the woods, I have a good ebike, and I've used it about a month as my main vehicle last December. But first, I fell off and ruined my knee, and second, I can't spend 60 minutes to get to the first grocery store. There are plenty of options for slow electric transportation. I need a car that can do 60mph.
