A crowd funding web site recently raised more than two million US dollars to fund solar roadways. These roads, claim the developers, will remain snow-free, and, at the click of a switch, can be transformed into car parks or even sports pitches. In this activity students consider whether solar roadways are worth funding. They critique claims using reasoning and evidence, and apply what they know about generating electricity in solar cells, to make a decision.
