California solar hits the road with a new project from SolarCity and California-based Rabobank: a series of five solar-powered electric car charging stations have been installed along Rt. 101 between San Franciso and Los Angeles. It's not exactly like stopping off for gas, as fully charging a car can take about three hours. Maybe you can become good friends with your local banker while you're charging--four of the charging stations are in parking spots at Rabobank branches. A few weeks back, I posted about the concept of highways paved with solar collectors; while this California solar corridor isn't quite the same thing, it's an excellent step towards a lower-carbon highway infrastructure. As the cost of electric cars goes down over time, and when charging and battery technology improves to speed up the process, this may become an important element of road planning.
