CalSol, the UC Berkeley solar vehicle team, has been around since 1990. Over the years the team has created eight generations of solar vehicles, each one getting closer to being ready for you. They have tested out at 80 mph, although generally they go in the 40-mph range after a charge of between four and five hours. The CalSol team designs, builds and tests these cars, including the current standard bearer, Zephyr. Series: "UC Berkeley News" [Science] [Show ID: 34483]
