Re: The discussion for the last few hours about vehicle-to-grid.
I made a post a while back, found it and pointed to it again, but I can't find it now so here's this:

Software Defined Electricity uses real time data sliced very finely to modulate the grid with, ideally, super capacitors. Rather than a centralized solution it would be distributed and used to suppress local spikes in demand. Acting in concert this would calm the grid so that a backup power plant isn't triggered repeatedly.
This would extend to the vehicles being able to contribute not by not draining the battery back to grid, but by modulating the recharge rate
enmass.
Given the nano-second response time required , everybody gets new hardware. I read the Tesla bought the supercapacitor company for some 'dry electrode' technology they hold.
