> I wager all by itself costs more than paving a traditional road.
Compared to a single road paving, the hi-tech road is more expensive but this road is supposed to be more durable than traditional paved roads. That means you need to compare the cost of several road pavings to get a more accurate comparison.
The hi-tech road is supposed to be installed once for several decades, where paved roads are re-paved every few years. This increases the cost of the traditional paved road.
Also, these hi-tech roads are supposed to subsidize their cost with energy creation.

Burying power lines is expensive. On its own, too expensive but combined with this project, it could be fiscally sound.
- danpat 12y agoThe key word is "supposed". If glass tiles were a good choice for road surfaces, I'd expect we'd have seen them in use by now. If it's just economics that have stopped glass tile use in roadways, I'm still dubious that the energy production from these units will come close to offsetting the additional expense.
- MichaelApproved 12y agoThis is what R&D is for.
- TTPrograms 12y agoThe first part of R&D is research, implying "research if this is even possible". The point people are making it's far from clear that this will work, so it's silly to assume that it will work a priori given the obvious engineering challenges.
- bronson 12y agoHumans have been researching and developing road surfaces for a few millennia now. It's going to be very expensive to find plausible materials that haven't already been tried. Especially clear ones.

- vacri 12y agopaved roads are re-paved every few years This is not my experience. I've lived near a secondary arterial road for nearly 9 years, and have never seen repaving done on it. It's still in fine condition.
- jacobolus 12y agoIn my limited understanding, the frequency of required maintenance depends heavily on weather conditions, and also on the size of vehicles who commonly travel on the road. Trucks cause orders of magnitude more wear on roads than cars do.
- vacri 12y agoWeather conditions it is, then. It doesn't snow here, though it rains a lot. But if snow is a problem, then a solar road makes much less sense anyway.
- dsfreed 12y agoI live in Michigan and the roads are repaved what seems like every other year. After each winter, there are potholes the size of craters on the moon. Very dangerous when everyone is swerving into incoming traffic and slamming on breaks to avoid them.
- chris-martin 12y ago> The hi-tech road is supposed to be installed once for several decades, where paved roads are re-paved every few years. We're comparing the cost of solar panels to the cost of pouring some shit onto the ground... I'd assume that difference is far more than tenfold?
