Seems very promising.
Surface traction question:
What are you going to do about traction? What's going to happen to the surface of the Solar Roadways when it rains>
We sent samples of textured glass to a university civil engineering lab for traction testing. We started off being able to stop a car going 40 mph on a wet surface in the required distance. We designed a more and more aggressive surface pattern until we got a call form the lab one day: we'd torn the boot off of the British Pendulum Testing apparatus! We backed off a little and ended up with a texture that can stop a vehicle going 80 mph in the required distance.

If this is true, the government should increase posted speed limits!![]()
No! Better traction makes the roads even MORE dangerous! We should lower the speed limit to 5mph/8mph! The reason: because of the childrenz!!!!![]()
