Bad mixture: windmills and tornadoes

You know that when a camera focuses on a single windmill... something must happen!

What you have just witnessed is not the norm. Windmills work best at air currents between 40 and 80km/h. However, due to new regulations state-of-the-art wind turbines must be designed in order to outdo in adverse situations (probably like the one above). They are designed so that they stop at a so-called "survival speed" of 208-320km/h.

What happened to the windmill of the video was that it had a break failure while trying to accomplish the security system.

Recommendation of the chef: Press "4" while reproducing the video.
