"So now your solution is to use a magic type of glass that you assert exists that will stand up to the wear and tear of traffic and also make it into a state of the art, finely tuned lens?"
You keep using state of the art. I don't think it means what you think it means, especially in context of date of invention of these things (some over 30 years ago.)
That magic glass? Easy. Transparent aluminum. We've been able to manufacture it in bulk for at least half a decade with ease.
"Even if you crank up the power in the LEDs to overpower the sun"
You failed to read the part where I mentioned that LEDs are far and above efficiency of the sun, didn't you? You also failed to think about the color choice of yellow-green, which our eyes are most sensitive to.
"You are trying to overpower the light-source that you are using to power your light-source. "
Given the purpose of a solar panel would be to ABSORB the light, overpowering it would not be a problem, as much light shouldn't be reflecting off for the most part.
You are certainly not paying attention to what people are writing and saying. Perhaps you should step back and, oh I dunno, actually obtain a degree in this kind of field so you might be able to understand what we're talking about?
