But that doesn't mean some serious effort isn't being put in. Down in Australia, where they have more sun than they know what to do with, there's this big solar-powered car race every year. The spatula-shaped cars that compete are about as weird as you can imagine, but they once said the same about the Wright Brothers' plane. Of course you can always put those solar panels on your house and plug an electric car into them, filling its battery when the sun shines. That's far less weird and far more doable.
