Idaho couple Julie and Scott Brusaw of Solar Roadways have raised more than $1 million on Indiegogo to pursue the extremely ambitious goal of replacing the nation’s roads with solar panels. The design will now move from prototype to manufacturing, a dangerous phase for any technology project — and while the dream is exciting, the logistics of actually pulling it off are less so. The Brusaws are not scammers or wackos. Scott has an electrical engineering background and the project has gotten two rounds of funding from the Federal Highway Administration. They’ve built a prototype parking lot made of solar panels, microprocessors, and LEDs encased in a textured glass that they say can withstand the weight of a 250,000-pound truck.
