To me, the most surprising part is: Holy fuck, Audi's have huge petrol tanks! I usually fill up my reasonably priced car in like a minute or so and it gets a range of some 700 kilometers on a ~40 liter gas tank.

5 minutes for a petrol stop? That's insane.

Considering human nature first, and the assumption that these battery swap sites will probably be unattended, I wonder how long before someone will work out how to steal those batteries?

I'd be surprised if it ever happens. I'm sure the batteries are configured to be useless in the wrong car.

It just becomes part of the cost of doing business. We still have credit cards, even though credit card fraud exists, it's just factored into interest rates.

If 1% of batteries get stolen (which is probably way higher than it'll actually be), then the price of batteries will increase by 1% to factor it in.

If that causes battery swaps to be uneconomical, so be it, the we'll figure out something else.

I would like to know is there a capacity for the number of battery replacements they system can do ? I guess they recharge your battery and pass it on to the next person when it's fully charged. How do they insure battery quality for the replacements. Still a F'ing awesome demo.

This is the key reason you'd want to do this in the first place. It not only solves the problem of quickly charging the battery, it solves the problem of battery quality over time!

The mere fact that you have batteries being swapped in and out of cars means you can systematically track battery health and refurbish batteries that are getting low, without ever having to bother the customer or affect the driveability of the car.

The $40 (or so) battery swap fee is not for the electricity or the infrastructure, it is an insurance payment on the battery itself. You're paying for the collective maintenance of all Tesla batteries, and in turn ensuring the health and ease of your own.

The last remaining argument against electric has always been the charge time, and "oh, but the battery costs $15,000 when it finally dies out"—I always knew a system of battery swap was the answer to basically everything, and I thought Tesla was doing it wrong by coming out with a fixed-battery car.

Turns out I was wrong. They're doing everything exactly right.

Seemed normal to me. I think my wife's BMW SUV thingie fits like 90 liters.

Can't wait to see Tesla grow and change the way we think about automobiles, at a species level.

Elon thinks most cars in production will be all-electric by 2030. I think that's achievable.

I really hope that by 2030, we are utilizing Graphite Super capacitors....with everything I remember reading, it sounds like a miracle material.

At 10 gallons per minute, that's still just 2 minutes pumping time. (23 gallons)

Edit: I checked again, he pumps for 2.5 minutes and gets exactly 23 gallons. So I guess the pump isn't as fast as Elon says on stage. But it still surprised me because, well, that's about twice as long as what I'm used to :)

Agreed. I never could have bought an electric knowing how batteries die. This eliminates that problem. Now if only my MacBook had battery swap capability...
