> No it's not, not unless you have Tesla style massive DC chargers. And they are not putting those in every supermarket. Regular chargers will barely give you enough charge to get home in that 30 minutes.

Not it's not, not unless you have IBM style massive cabinet hard drives. And they are not putting those in every home computer. Regular hard drives will barely give you enough disk space to store plaintext documents.

Sorry, you just sound like people that used to say things like "you'll never need more than 1 GiB of hard drive space." Things will evolve. It'll happen faster than you anticipate.

Wake up, we don't talk about computers. We talk about cars. Big heavy maschines that can't be shrinked and where the technic is not evolving as fast as the first years in computers. You will need the same amount of energy to bring a car today or in 20 years from a to b. And this amount of energy needs to be transfered to the place where you want to charge your battery. And there is the problem that will not change in 20 years. You can supercharge 5 cars an a parking lot now, but for 50 cars you need a complete other infrastructur thats bind on the same physics that cars have today.

And no, you never ned 1GB of hard drive for anything that was done with computers at this time. Now we use computers for completly other things. I suppose on cars the usage will not change as far as with computers.

> We talk about cars.

No, we're talking about batteries and charging. If you think battery tech is done evolving, wont shrink, and that "energy" and "power" are interchangeable concepts, then I don't think we can have a fruitful discussion.

> And no, you never ned 1GB of hard drive for anything that was done with computers at this time.

That was my point. Saying something wont happen based on what's happened so far is foolish.

I think the point is that if battery technology is good enough, it's not the limiting factor. Being able to deliver that much power becomes a bottleneck. At some point the owner of the parking lot will have to upgrade their electrical service, which could be expensive.

I'm not sure how much of an issue that really is, though. Even if all cars are EVs, it's not like every single grocery store customer is going to fully charge their car every time they buy groceries.
