Man, I am really getting tired of having to combat these faulty points left-and-right whenever someone says this is a ridiculous idea. The answers to literally all of those problems can be found in either the FAQ. The only figure that isn't answered there is a bit harder to find; the cost. Solar panel roads at current cost about [url=http://www.huffingtonpost.ca/2014/05/30/solar-roadways-indiegogo_n_5416811.html]70 dollars per square foot,[/url] which is admittedly more expensive than asphalt at around 15 dollars a square foot, but the price tag is going to go down as they become more prevalent and as they come out of the prototype stage, which they are currently in. It's also nowhere near the ridiculous 3000 dollars a square foot you're proposing. And actually, installation is relatively cheap as currently-existing roads are to be used as the foundation. On top of that, maintenance costs are reduced from one or more days to just a few hours, as maintenance consists of popping a broken panel out and another one in. So both of those are moot. Thankfully people who don't know anything about engineering aren't running the Federal Highway Administration, (who have contracted these people twice already) aren't distributing the World Technology Award and aren't in charge of the Institute of Electrical and Electronics Engineers. (Who have given them an award themselves) If they were then all of the potential in this new technology might be lost before it even gets off the ground.
