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.

Why assume the thief will want to use it? The scrap value of the copper and aluminium alone could make it worthwhile

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

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 :)

Did you watch the video? Not all of the time at the gas station is spent pumping.

Theft should never hinder innovation, and when you factor in the ambition of Tesla, I am very sure they will dedicate as much time and effort into theft deterrence as they do to ease of use.

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.

Likewise, I get 700 miles (~1100km) from a 10 imperial gallon (45l) tank.

With that said, it's not sensible to compare a modern european small car with the average US car. Particularly the class of car that the Model S is competing with (which are typically expensive, have a high capacity and relatively inefficient engine, and luxury interior).

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.

Well it does seem that most of the time saved when filling up the Model S comes from not having to get out of the car in the first place. And I guess the credit card gets used from within the car?

First why would you make the battery sites unattended anymore than the average petrol (gas) station is unattended? (particularly in the near term where these are essentially prototypes). Secondly here in the UK we have fully automated petrol stations and they have a low theft rate, high quality CCTV plus the need to put in a credit/debit card before it'll start pumping makes sure of that. There are other issues with…

Actually, to my surprise, it appears that batteries must be worth stealing. I was disappointed recently when cycling east out of Edinburgh to see that pretty much all of the solar powered lights along the path between Newcraighall and the Queen Margaret University campus have been systematically robbed. Initially I thought it was vandalism but after looking at a few it was clear that each one had been broken into for…

Used to work at Patagonia, who installed a large-scale solar array in their parking lot in Southern California. Over a few years, at least 4 panels were stolen (of about 150 I believe).

These things are all valuable, just have to account for that and protect accordingly. I'm sure everything is entirely automated and secure, and I'm sure there are going to start being attendants watching over everything.

I think the greatest thing to take out of the presentation is...

1. The Tesla driver does NOT need to get out of the car (screw rain and bugs).

2. It IS a reasonable time (no need to sit in a diner and wait)

3. The mileage limitation is becoming less limiting (no different than making sure a long trip has a gas station on the way).

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…

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