"But Who Will Build the Roads?"
As always, the market comes to the rescue through innovative entrepreneurship. And in this case, not only do these entrepreneurs promise to build roads - they will use the roads to generate electricity for sale on the market. So they solve two problems at once. Nay, three - the roads use part of the generated power to keep snow and ice off the surface, thereby making them safe even in cold weather. Wait, four - the roads can display lights to warn drivers of danger ahead such as wild animals.
The venture, called Solar Roadways, is fully crowd-funded (closing in on double what they requested) but is looking to "improve" existing government roads (which shouldn't be all that hard) rather than lay their own. Too bad government doesn't allow competition.
