Give it Up for the Dutch!

These beautiful, translucent barriers quiet traffic—and generate power at the same time

These beautiful, translucent barriers quiet traffic—and generate power at the same time

Driving the Dutch highways just got a lot more colorful. And this has to be one of the best Dutch ideas yet—roadside noise barriers that also generate solar power. Not only that, they work on cloudy days, and one kilometer (0.62 miles) provides enough electricity to power 50 homes.

The key is a new kind of solar panel. They’re cheap, they’re transparent, and they use a different light-gathering tech that works under the gray skies of Northern Europe. They’re called luminescent solar concentrators (LSC), and they’re translucent sheets which bounce light internally to the edges of the panels, where it is beamed onto regular solar panels “in concentrated form.”

The LSC panels can be made in different colors, so the result is something like an oversized stained-glass window. Because light can shine through them, they could be used in urban areas, shielding noise without making either pedestrians or motorists feel cut off.
