Why not ake it all the way and spend 1 year of Iraq on retrofitting every home in America with nano solar. Most days you make more than you use - put that back into the grid. Every bit you put back would get you credits for the days you need to draw FROM the grid. Then give us all a hydrogen cracker (solor powered) and run our cars and supplement our homes with the hydrogen. It's better solar transfer/storage than a battery. Then we are done! No more big energy!! No more Big OIL - think of the extra money stimulating the economy!
Let the Interstate trucks and farm equipment stay on oil until the residential is done and slowly begin to move them as their fleets age out.

other outputs for extra juice...your computer for working in the park ("telecommuting" with a view), running mobile operations like bike camps for the more mobile population- I've seen threads for this and "homeless" remediations projects. Remember its PURE D.C. 99,999 ripple free. just what the computers demand.

And yes, buy cheap (night) sell high (day) and sell local (remember there are HUGE line losses in the common interstate grids- more so in daytime high power draw hours. And there are other ways to "charge" My dreams are towards a mobile workout station, aka bike...which saves the added time and expense of a gym with that horrid music and all their smells (chemicals, not the organic sweat)...so I charge with bioavailable callories, and sell the exercise instead of rent it.

Maybe I'm too hippie/spartan for this brave new labor reduced world?

I guess I'm your typical V2G user (provider). I have two cars, one my wife drives to work daily, the other only gets used on Sunday's when I need to get to places the train doesn't go. I would be delighted if my car served some secondary and possibly profitable purpose throughout the week.

No doubt there are others who who use their car on weekdays, but rest on Sundays. Add up all these bits and the number of garaged cars at any one time is remarkably consistent if averaged over many thousands.

So while my car is powering the great city during the day how will I have juice to drive home at the end of the day?

As someone not too up on the economics of battery storage, I wonder what the real selling point of V2G would be.

What sorts of situations would cause a regular car user to wish to drain their car's power during the day by selling it to the grid. Perhaps one might fully charge one's car overnight, and then, once one has driven to and from work, sell the bulk of what's remaining back to the grid (leaving a little behind for an emergency in the evening)...?

Presumably V2G is in some way better than large-scale battery storage (which I'm guessing would benefit from better control and economies of scale). Does it, in essence, come down to the fact that V2G takes advantage of battery storage that would exist anyway, as opposed to requiring batteries specifically for the purpose of storing night-time electricity?
