How to transport those long windmill wings over the highways?
United States Patent No. 7,429,156, issued last Tuesday.
Windmill wings (as this patent refers to them) or vanes keep getting longer and longer. As greater efficiencies are being discovered in long windmill vanes, vanes of 200-300 feet or more in length are no longer uncommon.
The transportation of any manufactured item of that size, in one piece, can be challenging.
In this newly issued patent, Jorge Jensen of Denmark has proposed a solution for transporting these vanes from the point of manufacture to the point of installation.
