Can our National Highways double as power grids?

There are about 70,548 kilometers National Highways alone, and thousands more in state highways, suburban thoroughfares and rural roads (approx 33 lakh Kms). Could all that asphalt be replaced by solar panels and emedded with conductors to feed solar and wind power generated enroute- and that would also double as the nation's power grid?

A pure creative outside the box, yet pragmatic thinking involved in this idea. The obvious solutions that this idea could offer to the world are obvious. Can India beat China in Green Power Technology?

This is the kind of thing worth risking a fair amount of money on. If it can't be made to work cost-effectively, it really is an idea that society can comfortably say "Ah well, it was worth the try."
