Solar Freaking Roadways!  This is even better that the smart roads i have been reading about for years!  LED roadways make so much sense.  Not just to warn drivers of obstacles ahead, or to change parking lot configurations.  It can even change lane configurations based on traffic patterns.  Like the golden gate, our roads could shift the number of east vs west bound lanes to account for traffic. The only down side is the cost, i’ve seen estimates all over the map.  How much did our present roadways cost if you added it all up?  I bet that has been plenty expensive as well.  What about the Railroads?  These things are expensive, but infrastructure is worth it.  When we spend money like this we are paying ourselves to build a better tomorrow.
