Science/Tech See other Science/Tech Articles Title: Solar roads that could power the entire U.S. are on the horizon ScienceAlert A company is raising crowd-sourced funds to turn the U.S.'s roads into giant energy farms. According to their Indigogo page, a company called Solar Roadways want to cover every highway in the U.S. in thick LED-lit glass solar panels. There are around 30,000 square kilometres of roads in the U.S., so if their plan is successful, the energy-generating potential is huge - in fact, is every paved surface was covered with their solar panels, they would produce more energy than the U.S. consumes. Solar Roadways' hexagonal solar panels can generate enough power to light the road, melt ice and snow, and send leftover energy to cities. The was first presented in 2010, but now the founders Scott and Julie Brusaw have actually set up a working prototype in a parking lot outside their lab in Idaho. And it works The tempered glass panels not only generate energy sustainable, they also offer a superior road surface to traditional materials - they're around 1.5cm thick and withstand fully-loaded tricks and even 113,000kg trucks driving over them. And although they're glass, the surface isn't slippery and won't ever get iced-over as it's self-heating. It will also be able to show road markings and send up-to-date traffic messages to drivers through the inbuilt LED lights, and won't ever get potholes. Even cooler, if rest stops or parking lots were paved with the solar panels, they could offer charging stations for electric cars. In the future, the Brusaw's think electric car users might even be able to charge the cars directly through the road as they drive - which means they'll never have to stop. So what the hell are the downsides? Well, the system would require a trench down one side of the road to hold power cables, Engadget reports. But this isn't necessarily a bad thing as it could also be used to store cables for a future high-speed data network. And because each panel is wired, it makes repairs extremely easy. When one panel becomes faulty, the others around it let a repair person know their location. Perhaps the main downside is that the project is expensive. The company is currently trying to raise $1 million to do more testing and refine their current product, as well as paving some smaller roads and parking lots. They'd need a lot more money if they wanted to pave the entire U.S. road system. But when you compare that to the price of relying on fossil fuels, maybe it's not that steep.

LOL! Has the author seen the potholes in Chicagoland? Japan or Singapore or Switzerland could do something like this.
Potholes are caused by water/ice damage to the asphalt. If this tech keeps the roadways warm so it never freezes, and/or otherwise doesn't absorb water, then potholes shouldn't be an issue. That might actually be a more valuable aspect of this tech... eliminating road repair costs.
This looks like beautiful technology to me.
