It depends on the drainage system. It is possible to set it up in a way that the water never has to touch the circuits.
Does the word "condensation" mean anything to you?
It does. But if they're sealed completely within glass then it wouldn't matter. However, I don't really know exactly how the panels are set up or if the circuit boards are sealed inside.

Now, concrete is harder and stronger than glass.

I don't know that it's the case that concrete is harder and stronger than glass.
Really?

This calls... FOR SCIENCE!

Oh snap.

After doing some "research" it looks like concrete has a hardness anywhere between 5-9, depending on what it's made of. Glass is anywhere from 6-7, so some glass is harder then some concrete. It looks like typically, concrete has a compressive strength of 5000psi, whereas for glass to be considered tempered, it would need to have a compressive strength of 10,000psi. Also, going the other way, concrete has very poor tensile strength.

Over the centuries, a variety of materials have been used to make roads: dirt, gravel, cobble stones, bricks, concrete, asphalt, etc.  If glass is such a wonderful material, then why hasn't anyone used it to make roads before now?

First and foremost, we had to get to a period of time where we have tempered glass - so after 1900. Then you sort of need to wait for it to be mass produced and accessible. And then you just need someone who is tired of potholes and ready to think of something new.

Glass is definitely a wonderful material.

As this keeps going you think of more and more unimaginative arguments. It's fine if you hate the idea, but "why wasn't it ever used before" is not a good argument.

I'm sorry, but how does glass solve the pothole problem?  ???

I don't hate the idea, I just think that it's overly ambitious and they need a reality check.  I think that "why wasn't it ever used before" is a very good argument, especially if you're considering a multi-trillion dollar investment. 

Then again, I don't suppose that the question a viability will really be answered until these guys actually lay down a few hundred yards of roadway for some real world testing, not the least of which being the question of actual energy production vs consumption of the system.

Here's a better question:
Why did they use all those other materials?  If asphalt is so great, why didn't they just start with that and skip the other crap?

Perhaps true, but to be fair the original witty arguments were never really countered.

It's fine if you hate the idea, but "why wasn't it ever used before" is not a good argument.

Actually it is. It's the first thing an inventor should ask. It's a reality check. If it's a good invention then the answer is "because I'm the only one the see how these things can go together", or "I've discovered a new material that can do x".

I reckon tempered glass is pretty expensive. I reckon tempered glass, as currently manufactured, has a low friction coefficient.

So does the inventor have a supply of cheap tempered glass? Has he invented a way of producing tempered glass that's vastly cheaper than current means? Has he discovered a way of making tempered glass with a friction coefficient equal or greater than asphalt?

All signs indicate no.

Likewise, if Xbox One is so great, why was it never created until now? It's a terrible argument.

The components didn't exist before.
Unlike asphault and aggregate which has existed for millions of years.

Except Solar Roadways isn't the Xbox One. It's more like the Ford Nucleon: something we have the technology for but nobody asked for and is a potential disaster.

I never said that asphalt is so great.  If anything, asphalt has some pretty significant disadvantages compared to some other materials, which is why all of those other materials are still in use today.  Then again, asphalt has some pretty significant advantages too, so it becomes a question of which material is most appropriate for the situation.

So, one the significant questions that needs to be answered is how do the pros and cons of textured, tempered glass compare to asphalt and concrete?  After all, if glass can't be made into a suitable road surface, then everything else is moot.

Glass has existed but we're speaking of tempered glass.

Any arguments that were not countered was probably because I am not an expert on this. All I'm doing is using my imagination and facts/claims from their website.

There have been great arguments here and I'm willing to listen which is why I created this thread. However, "if Z is so great then why wasn't it invented before X and Y" is not a good argument.

Questions on the production of tempered glass are reasonable, as far as I know all of the donations are going to more R&D, wages for engineers, and tackling the production issue.

It depends on what you are arguing. The question "If x is so great why hasn't it been done before" is a good starting point. If taken seriously, the answers will help determine whether it's a good idea to try "x" or not.

In the case of Solar Roadways, answers like "because glass is too slippery, will get scratched, etc" and "because the solar panels don't generate nearly enough power" highlight the problems right away. It may not be an argument itself, but not asking that question at the beginning of a project would be short sighted.

Why hasn't glass been used before?  Because it is brittle and likely to be shattered.  Okay, let's make it tougher and shatter resistant!  Check.
Because it is slippery, especially while wet.  Okay, lets texture the glass a bit to provide traction!  Check.
But with texture, won't it be useless as a solar cell?  As you can clearly see, light is still pretty easily able to penetrate the glass!  Check.
