A while ago I wrote a post, Roads: Why Are They Still Asphalt? In it I expressed my desire for the future of road materials. No more hours idling in construction zones as they pour more oil to patch another season’s worth of a billion or so potholes. Better drainage and more traction during slippery conditions. Why weren’t these goals being pursued by the best and brightest of engineers? It turns out, someone was indeed working on this problem and it’s looking even better than I had hoped.
Julie and Scott Brusaw in Idaho are developing solar roadways. Here’s the quick version of all the awesome their new road promises:
- They use high-durability, textured glass to cover hexagonal solar modules with internal heaters and LED lights.
- It exceeds standards for weight tolerance, toughness, and traction.
- LED’s mean clear road lines forever, no paint, and alerting drivers to pedestrians as they step out onto crosswalks.
- Heaters deal with snow and ice.
- Modular roads mean broken pieces are quickly identified and replaced.
- Electric cars will be able to plug into the road to recharge.
- More features and details in their FAQ
- No more potholes-ever


What we have here is technology that greatly increases road safety, greatly decreases the use of fossil fuels, and it encourages the development and use of electric vehicles. It’s everything my last article asked for and more.
The obvious question is, while this all sounds great, can this new road feasibly deliver on all that it promises? I don’t know, but in the spirit of my last article, I don’t think it matters that much. If we really are at the cusp of a road revolution and kids 20 years from now look back at asphalt roads the way we currently look at VHS tapes, all the better. However, my cynical side is well trained, and I doubt such a smooth victory is forthcoming. But I’m STILL excited. These solar roadways are here, they are being tested, and people are talking about them. Even if, in this iteration, they are a dismal failure, the seeds of progress have been planted. Whatever unforeseen problems arise, we will learn from them. While I’m unsure of the rate of road progress, I’m thrilled to know that, slow or fast, it’s actually happening. So read all about it, spread the word, and let’s see if we can get this happening sooner, rather than later.

Hey – if Nissan can charge an extra $1,000 for “Nano paint” (your car will never get dirty again because Nano chips toss off dirt) then solar roads are completely within the realm of possibility :)

I saw a video of that and a few other hydrophobic projects. Wild stuff. Still, until they go from ‘we have the technology!’ to ‘we convinced society to start implementing this technology’, I will remain cautiously optimistic.

I shouldn’t comment so early in the day. I start some things in my head that just shouldn’t be.
Imagine no construction zones
And no potholes too
Imagine all the people
Driving electric caaaars
You-oo-oo-oo-oo…
Sorry, I’ll stop now.

As a first step, even if we aren’t ready to completely pave our roads with this material, we could certainly start with paving the shoulders in solar cells and making our guard rails solar too. There’s all that space that’s mostly bare and unused, with the sun beating down on it everyday. It would be a good test for hooking up the system and figuring out the logistics of putting in that kind of power grid.
My only other concern is that we’ll need a lot of whatever material the photovoltaics are made from, and if the US does not have an adequate supply it may leave us dependent on some other country we’re not on good terms with. But that still might be an improvement over being dependent on Saudi oil!

Oh yes, it will definitely take many steps. On their website, they say they plan to start with driveways, parking lots, and things like that. From these smaller projects they will learn and further refine the technology. Then they can move up to residential roads, city streets, and finally highways.

I need to input, like a bunch at the same time as I hadn’t the benefit of examining everything you had to declare, I couldnt rally round on the contrary elude draw your attention before long. The as if you needed an excellent grasp on the subject beakdfdbadak

I recall last year (i think) in Montreal, they were beginning to use a more environmentally friendly asphalt alternative for patching holes … only to have the old-school asphalt companies sabotage its use to make it look like an inferior product. It’s those with money on the line that will be one of the biggest hurdles for positive change.

Well, that’s depressing. How far it is from surprising is even more depressing. Hopefully, word of solar roadways will spread far and reach enough friendly ears that we can muster a strong enough voice to overcome such hurdles.

I saw this project back when it was green lighted back in 09. Glad to see it come from idea to concept. I think it would be awesome to have the road in front of you to act as a vehicle message system. Your car could communicate with the road, and transmit gps data so that you don’t have to take your eyes off of the road. It could also serve as a warning system for accidents, Amber Alerts, etc. the replacement cost would be long term beneficial, not to mention the savings on salt and maintenance. If it also sent power to the local grid and eased dependence on fossil fuels it would be a huge step toward energy independence.

Yes, the amount of potential good that could grow out of this technology is staggering. I mean, no more icy roads, no more shovelling walks and driveways. It is a glittering image of a sustainable utopia. I hope it gets the public traction required to start realizing some of that potential soon.
