Why It's Bullshit:
Say, have you seen many solar panels laid out flat on the ground? Probably not, because those suckers need to be angled to face the sun directly in order to feed off its light-blood with any kind of efficiency. So for them to produce meaningful power, all of our roads would have to bank, sometimes sharply. And we're not saying we personally don't want that; it would be awesome! But some buzzkills would probably complain about the drastic uptick in fatalities that resulted from us turning every freeway into a NASCAR track.
Furthermore, according to British scientist Phil Mason, if we were to cover all roads in the U.S. with solar panels, the cost of the glass alone, without all the electronics and labor, would be $2 trillion.
"What if we skip the shitty states?"
We also have to consider the fact that, unless you politely take your tires off before driving on them, roads get dirty. Dirty solar panels are as good at producing sustainable energy as hamster wheels. Put it all together and it becomes clear the solar roadways will never be as good as asphalt, which, by the way, is also 99 percent recyclable. Solar roadway tiles are not.
