Solar road technology comes to Route 66
The tiles will be familiar if you’ve followed Solar Roadways before. Each one combines a solar cell with LED lighting, a heating element and tempered glass that’s strong enough to support the weight of a semi-trailer truck. If successful, the panels will feed the electrical grid (ideally paying for themselves) and make the roads safer by both lighting the way as well as keeping the roads free of rain and snow. They should be easier to repair than asphalt, too, since you don’t need to take out whole patches of road to fix small cracks.
Of course, “if successful” is the operative term here. The real litmus test comes if and when Solar Roadways subjects the tiles to the legions of cars traveling on Route 66 and beyond. Missouri has a strong incentive to make that happen, though. As the Transportation Department’s Tom Blair observes, it would be odd to push self-driving cars in the state’s Road to Tomorrow initiative when the streets aren’t as smart as the vehicles using them.
