In case you hadn't noticed, none of us here at Jalopnik is a physicist. That's clearly evident by one of our early inventions, inspired by a Popeye cartoon; that is, a sailboat powered by an on-board electric fan. It didn't work, and we narrowly escaped electrocution. We recalled our ill-conceived efforts as one reader of Make magazine wondered whether a kind of electric windmill can be deployed on an electric-powered car's roof to provide an additional source of energy at highway speeds. Sure, it sounds as cracky as our own attempt, but would it work at least in theory? Or would there be a net loss of energy? Read on.
