Around 2000, Popular Science / Mechanics had a small write up on an electric van with a fan on the roof. ( It was mounted horizontally. )
The blades were designed in such a way that they would fold flat as they turned, thereby reducing drag.
They claimed that even in a parking garage, the wind would turn the blades.
So agreed - not such a stupid idea after all. I wonder what became of the prototype though.
