The nacelle hub height sits at 607 ft (185 m), while the blade diameter is a whopping 1,107 ft (310 m). It has a blade swept area of 812,424 square feet (75,477 sq m). Do you know what else has about that much wingspan? Twelve Boeing 747s. You'd need an area the size of 14 NFL football fields, or a decent city block, to lay it down. It's a bit big.
