What are you going to do about traction? What's going to happen to the surface of the Solar Roadways when it rains>
Everyone naturally pictures sliding out of control on a smooth piece of wet glass! Actually, one of our many technical specs is that it be textured to the point that it provides at least the traction that current asphalt roads offer - even in the rain. We hesitate to even call it glass, as it is far from a traditional window pane, but glass is what it is, so glass is what we must call it.
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.
How much weight can these panels support? Semi-trucks get pretty heavy!
Originally, we were designing toward 80,000 pounds. That was supposed to be the maximum legal limit for a semi-truck. However, we live in logging country and a former logging truck driver informed us that they don't have scales in the woods and that he'd topped out at 124,000 pounds. So we decided that we should go for 150,000 pounds. We then learned that oil companies can get permission to move refinery equipment up to 230,000 pounds on frozen roads, so we decided to shoot for 250,000 pounds.
Both 3D Finite Element Method analysis and actual load testing at civil engineering labs showed that our Solar Road Panels can handle that and more.
So.. great job of avoiding the biggest problem with Solar Friggin Roadways..
T R A C T I O N !!!!!
Wanna play basketball on it? Slip and kill yourself.
Wanna drive on it? A couple of raindrops and you`re dead!
But hey.. solve the problem of creating a substance with good traction with both rubber and the "not rubberized" future wheels - AND being able to let enough light through. Well, then I`m sold.
And yeah, to the peeps that don`t know what I mean with the "not rubberized" future - look into where rubber comes from - and take a wild guess whats gonna happen to rubber when oil stops flowing or is replaced.
Whoop, there it is!

That is understandable but as far as the tracking goes.....uhm...do you own a cell phone?
however I think those costs can be hugely offset if the roads are proven to have better longevity than our current road system. - See more at: www.abovetopsecret.com...
