Yet another interesting solar innovation... we need to keep thinking like this, especially in our sun rich country where solar is already clearly commercially viable. Solar car parks, anyone? Solar glass in new construction instead of glass that produces no electricity? Here's the excerpt:
Highway noise can be a nuisance. Highway noise barriers can be hideous.
Now researchers at Eindhoven University of Technology have a found way to make highway noise barriers not only more beautiful but also function as solar power generators.
As part of the Solar Noise Barriers project (SONOB), a team will spend a year studying how well the luminescent solar concentrators, which measure 16 feet wide by 14.5 tall, work under a variety of conditions.
Initial tests show that .62 miles (1 kilometer) of the barriers could supply electricity to 50 households for a year or supply an electric car battery with power enough to drive 560,000 miles (900,000 km).
