Catching Big Air

Despite the lagging economy, 2010 is already shaping up to be an impressive year for design that pushes limits. First, we witnessed the opening of the Burj Khalifa, the world’s tallest building by some 40% over the next tallest structure. Now, we can view the world’s tallest wing sail—designed by BMW Oracle Racing for the America’s Cup race.
Taking full advantage of the unrestricted design rules this year, BMW has created a staggering wing sail nearly 200 feet in height. Constructed of kevlar and carbon fiber, the wing is larger than a Boeing 747 wing and spans up to 30 feet in width. Given its weight, the sail will require motorized controls as opposed to conventional ropes.
If all goes well, the wing sail should outperform fabric sails substantially—since it won’t deform like conventional sails. However, the sail is just now being tested in Spanish waters, and it’s difficult to predict how the boat will perform in this cutthroat event, which begins early next month.
