It seems that V2G along with normal wear and tear would reduce the life of a car battery quite a bit.<BR/><BR/>If that was the case then what sane car owner would allow his car to participate in this type of program, which means we would have a serious energy shortage.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-48278009509397160672009-03-09T12:56:00.000-05:002009-03-09T12:56:00.000-05:00Iad,We reached Peak Pixie Dust a long time ago.

This is a lifetime total of 100,000 kWHrs of energy through the battery. If the battery costs $28,000 as reported by Charles Barton, we have a cost of $0.28/kWHr for the battery alone. Now add the cost of electricity to charge the battery in the first place, and we have some rather expensive electrical energy.<BR/><BR/>This sort of cost may be tolerable for a few hours per year when everybody is running their air conditioners. But with wind and solar, one would see these costs nearly daily.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-89240645817395516232009-03-09T08:03:00.000-05:002009-03-09T08:03:00.000-05:00You didn't incorporate the power of pixie dust int...You didn't incorporate the power of pixie dust into your analysis.

As I read it, I was thinking not only would it take a significant new population of serial hybrid cars, but also the interface to connect those vehicles. Unless you have a suitable garage or carport and plan to stay at your residence for quite some time, many people might not partake in voluntarily cooperating to make this work, even if it could.<BR/><BR/>Also, wouldn't this grid backup be available mostly at night when demand is lower and wind speeds might be up?<BR/><BR/>I would like to think that a major component of the green movement would be to create more livable communities where people are less dependent on cars. Newer suburban communities plan with sprawl in mind. Denser communities where walking and bicycling can potentially reduce those numerous short trip car trips that the volt hopes to do with its battery. The essence of this car battery grid backup seems contrary to that ideal. I think creating more walkable/bicycle access is an easier sell than trying to reengineer the grid infrastructure.Jason Ribeirohttps://www.blogger.com/profile/06863185203119704249noreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-5727225037742423682009-03-08T21:12:00.000-05:002009-03-08T21:12:00.000-05:00Nice debunking of yet another case of magic thinki...Nice debunking of yet another case of magic thinking :)Anonymousnoreply@blogger.com
