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.

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 :)

This is a ridiculous discussion. It takes about 3-5 minutes to fill up a large-tank performance car, similar in features and trim to the Model S. It takes about 2-4 minutes to fill up a smaller car. It takes less than 2 minutes to "fill up" a Model S. It takes about 10 minutes if you also use the restroom. Are we going to start factoring that into the comparison? If not, I'm out.

They have your serial number. I'm sure it's just billed directly to your card on file.

I saw it and wondered "what about dirt"? Dust, gravel, spilled oil, the stray coke can. Rain (yes it does sometimes rain in California). This is a fine stage demo, but really? We're talking enormous sealed electric bombs, swapped out by automated wrench and jack platforms, then a subterranean battery-storage-and-recharge system. The bigger technology than 'doing it at all' is 'keeping it working under environmental conditions'. Any info about that?

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…

So, $40 times 375 == $15000. That, what, 37500 miles? Sounds worse, not better.

You're going on long trips every single mile?

Otherwise you're charging it at home, at work, or using a supercharger while you eat lunch.

You may only swap the batt 10 times or less in those 37,500 miles. And you still get all the battery-quality advantages.

So you think a company that designs electric vehicles can't secure the batteries? The damn things come from underground. Not to mention the service station connects to the car somehow before doing so, because well as Tesla said, the battery is tied to your account. I wonder how long before people start thinking before posting their opinions on the internet... Can't we all just use some common sense before we start ju…

Banks and post offices get robbed every day. That problem is still not solved.

Apart from the extraordinarily rare successful heist[1], banks get robbed of teeny tiny amounts. That problem is effectively solved.

This doesn't break self-charging. You could use the same battery pack for a couple of months and then do the battery swap when you're doing a long distance drive.

Between cars sexier than swimsuit models, and owning all the infrastructure to support them Tesla has a real potential to be a giant company. I don't usually buy individual stocks, but Tesla keeps looking more lucrative in the long term. If he can survive in the short term, there's a great future.

What's probably most relevant is that it would take roughly as long to half-fill the Audi as to replace the Tesla's battery. That's in many ways a fairer comparison, as the Model S has roughly half the driving range of an Audi, and (I think) most car gasoline fill-ups aren't from near-empty back to full.

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.

It potentially also enables the used car market. I definitely would be hesitant of buying a used tesla if i knew there was a potential 15k bill waiting for me very shortly.
