Who Will Supply the Batteries for Plug-In Cars?

Lots of "pie in the sky" here.

If the utility wants to remove power from your cars battery you would have to have an inverter installed to convert DC back to AC at the proper voltage and frequency. Who's gonna pay for that?

If you go to use your car at peak periods (morning and evening) and you find the utility has been removing power from your battery you'll be leaving home with a partially discharged battery. Are you prepared to put up with that?

Every battery has a certain number of charge / discharge cycles that make up it's life expectancy. Is the utility gonna compensate you when the battery has to be replaced early in it's expected life because the utility has been using your car to store wind energy?

We are months away from the ultra capacitor which makes batteries obsolete. Think fiber compared to copper phone lines. Think digital photography and Eastman Kodak. When they become available, expect that sort of impact on the industry. Maxwell has a early version of a super cap in service overseas right now.
