Win one for the Zipper

This is a nice enough idea, separating the battery from the car, linking power generation and distribution, and then essentially selling you the "minutes" rather than just the car and then going your separate ways.

But they need to go one step further. This model won't scale in the US; we're too big, too mobile, and nobody is going to stop 18 times to replace a battery just to relocate or haul the family truckster across country (talk about running out of gas; you'd need a forklift to bail you out).

What they need is for a business model here is a sort of Ultra-Zip Car. You don't buy anything other than a use-privilege. You're a member, and, in fact, ultimately not that many cars are privately owned. A few gas-powered cars or clean-diesel hybrids are in the fleet for edge tasks that just don't make sense on 100% electric supply. When you move, you leave the car right where it is. There will be thousands just like it where you arrive. Something like that could genuinely be deal-changing and, over the course of many years, could fundamentally restructure how we think about transportation in this country.

Tie this model to green energy (as they note they're specifically doing in Denmark) and suddenly you've gotten around the generation/distribution connundrum of technologies like wind. Just store it in all the cars and get it back later (if you need it in a pinch) from the cars plugged in. Texas suddenly becomes the Saudi Arabia of wind energy.
