    "Why is that unusual? Because a high-profile start-up called Better Place built an entire business around the notion of battery-swapping, and it proved to be a disastrous mistake."

    Perhaps BP should have focused on selling cars first before spending nearly a billion dollars of investor money with no revenues.

    1. Is 20 minutes really far longer.

    2. Keep it simple and it's just another (rarely used?) arrow in Tesla's quiver.

    3. Better Place spent nearly a billion dollars on infrastructure before selling a single car (saying that one always makes me chuckle)

    4. Tesla is using Model S battery technology to power cars, to smooth out peak power use and to get excess solar on the grid at peak hours, why not get one more source of income from the few drivers that may want to swap.

    I think that he is showing capability; that it is possible to quick-swap the batteries in a Tesla vehicle. Battery swapping technology does have its problem, the biggest of which is cost. Another is the problem of not owning your battery or getting a battery that has less capacity than the original.

    I highly doubt that Elon Musk plans to build a network of battery swap stations. He already is building a network of Superchargers. High speed chargers are the future, for various reasons; the biggest being cost. A Supercharger can be built for about $300,000 which is dirt cheap compared to a battery swap station ($500,000) or gas station ($1.2 million).
    Thirty minutes is not that long.

    Again, I think that he is just demonstrating capability.

    If the big oil companies were smart, they would be working with the car companies to come up with a standard battery and a standard way to automatically change those batteries out at a "gas" station. For example, each electric car might have a battery tray on the underside that could be accessed by an automatic changer, akin to an automatic car wash. Pay your money, pull into the battery changer, wait a couple minutes, and pull away with a fully-charged battery.
