I agree entirely Lee, I have been saying for a couple years that V2G is nearly impossible to implement on a large enough scale. I have allowed the power company to reduce demand during peak hours my water heating and air conditioning consumption. For $14 in monthly credit. However I feel that V2H for reducing my own demand during peak usage times, with a Time Of Day rate adjustment, would be personally economical. Just charging during lower priced times and operating a few pieces during high priced times with power stored in the EV, or perhaps more reasonably, in a stationary battery pack, of lower cost of investment. Like a Solar P V backup battery.
