World's First Solar Powered Highway Opens In China - Windvoltz

In Jinan, the capital of the northeastern Shandong province, traffic is now rolling over a stretch of expressway that’s also generating electricity from the sun, according to state-run CCTV (link in Chinese). Extending for 1 km (0.6 miles), the stretch is made of three layers: transparent concrete on the top, photovoltaic panels in the middle, and insulation on the bottom. The area covered comes out to 5,875 square meters (63,200 sq ft).
