Coat roads and highways with this stuff. Make use of all the infrastructure out there. The DOT/states/counties could sell enegry back into grid, pays for road repair and upkeep.
and you could drive around in electric cars that have a "brush" touching the road. Like giant slot racers or "bumper cars". hehehe
well.. I don't know how well it would sitand up to road traffic but, I could see then putting cells along the highway,
you know like they have powerlines along the highway... this way if they had a problem they could get to it easily and do repairs... hmmmm.... And we have lots of highway to line bothsides with panels :)
