The caption should read "Bubba said, Oh! That's what the new bolts were for."

OOPS!!!!!!

That looks expensive. Its just a matter of time a ship looses directional control and collides with one of those.

It's actually a part of the continuous process improvement. They're supplementing the wind power with wave-energy capture devices but using the same infrastructure. Sort of a twofer.

Thats a $100,000 boo boo, who's calling the boss

I'm amazed how flimsy the blades seem to be. I know these are not the stresses they were designed for, but that one on the ship side seemed inordinately fragile and floppy, even considering it hit the ship and had a tagline attached.

You ever watch the wings on the airplane you are flying on as you taxi along? Or as you fly through turbulence?

I understand, from having built a number of large flying scale model aircraft and taken engineering classes covering such designs, the necessity of both light weight and flexibility in wing structures (which wind turbine blades essentially are). But I was surprised how flimsy those blades seemed to be. A long while ago, I watched a 777 (if I remember correctly) static wing deflection test, and they bent that thing nearly 30 feet before it failed! I know these were different sorts of loads from that, but the blade on the ship side appeared to go limp like a noodle for its entire length when it struck.
