These Beautiful, Translucent Barriers Quiet Traffic—And Generate Power At The Same Time

These Beautiful, Translucent Barriers Quiet TrafficAnd Generate Power At The Same Time

Where could this be? The Netherlands of course, where it seems like all such clever plans start (solar bike path, anyone?).

And this has to be one of the best Dutch ideas yetroadside 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 plan seems so obvious, you wonder why it hasn't been done before. But 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.

The test, which launched on June 18, along the A2 highway near Den Bosch, includes regular solar panels as a control, and also to see how both kinds of barrier fare in the outside world, when subjected to real life and real vandalism.

The project is being run by researcher Michael Debije, at the Eindhoven University of Technology. Debije's breakthrough is this new kind of LSC panel. Regular LSC panels reabsorb light as they channel it to the solar arrays at their edges. Debije's panels fix this. Added bonus: they also look good.
