Interesting piece, but I think the author is wrongly conflating two different applications of renewable energy - broad application (ie, used to wean us off oil, power homes, etc. etc.) and specific application (small scale). Solar roads may not offer a breakthrough for the former, but it could affect the latter. At the moment, we don't really know as the tech is all relatively young.

That's funny, I never saw the "Solar Freaking Roadways" video before. I think that the concept of having the panels do all those different things would result in power going into the panels from the grid not out of the panels and onto the grid. This couple seems to have had a wonderful idea that sounded cool and plausible while smoking a joint in the comfort of their house but in reality it does not look like it works too well. The Dutch on the other hand actually did this. Here is what an actual working testbed for a solar road looks like during install.  They actually make power with their 100m stretch. http://www.globalconstructionreview.com/news/100m-dutch-solar-road-g5en8er0at2es4-e4nou6g0h8/I assume that the French are looking to use the Dutch model, not the version of that nice stoner couple from Idaho.
Is that the ultimate thickness? My nephew and his Big Wheel could wear that out.
Looking at the photos of it on the web I don't think the Dutch one is intended for motor vehicle traffic because all of the photos show bicycles on it. With that said, the concrete there looks to be eight inches maybe more. The interstate highway system here in the USA uses 11 inches of concrete. So the build of that is not completely off base. The roadbed they are using looks soft though which is why I thought it might not be a motor vehicle road. It would probably make more sense to put the solar panels over the bike path

While I adore Sagan, own all of his books, have pdf copies of nearly everything he wrote that I can get my hands on, and consider him one of the best science communicators ever - I have to disagree with him on including Columbus in his comment. Yes, I'm being nit picky and yes I get the underlying meaning of his comment, but honestly...Columbus, as the evidence points out, was an ass. Now granted, just because you're an ass doesn't mean you're disqualified from being a genius, but still, what a douche.

It would probably make more sense to put the solar panels over the bike path It's less likely to hold up to the wear and tear of an interstate highway. But less traveled rural and residential streets might be an alternative.

Columbus would be an ass by 2017 standards, but with regards to 1492 he was perfectly normal.
