This document discusses solar roadways, which consist of solar panels embedded into roads, parking lots, and walkways to generate renewable energy. They have three layers - a surface layer made of durable, translucent materials with LEDs; an electronic layer with solar panels, microprocessors and sensors; and a bottom layer to distribute power. Solar roadways could power homes and charge electric vehicles. They provide benefits like reducing fossil fuel use, informing drivers, and keeping roads clear in winter. However, they also have high upfront costs compared to traditional asphalt roads. The document references several sources on the technical aspects and feasibility of solar roadway technology.
