Wind Power Generator Failure, Incredible

Incredible

The gearing inside slipped and the brakes failed, the technicians couldn't repair it in time and had to evacuate when the wind got too high. The police setup a 400m safety perimeter so nobody got hurt.

Apparently, some of these turbines are supposed to rotate to be perpendicular to the wind if the wind got too high, and some have automatic folding blades.

The blades failed from the aerodynamic stress and centripetal force, and one sliced through the fiberglass tower.

Sorry it's not a robot but it's just so cool!

I heard that it takes more energy to produce(manufacture), transport and maintain a personal wind turbine than the energy it produces in its lifetime - they just get made by countries who dont care so much about global warming (not that im so bothered, it just seems like it could be true)

Also i heard the same about energy saving light bulbs.

In the UK we used to use Halon fire extinguishers but when these became counter productive to global warming, what happened? They simply sent the excess unused ones to 3rd world coutries who didnt care about global warming. Now how does that help?

Solar panels have the same problem.

I've seen those things transported. it takes one semi trailer for one blade. they are huge

Not true.  Solar panels have at maximum 4 year payback time (in energy, not cost).  Newer panels payback in one year or less.  If that wasn't true, then it would be impossible for any manufacturer to make a profit.
Any intelligent fool can make things bigger, more complex, and more violent.  It takes a touch of genius - and a lot of courage - to move in the opposite direction.  ~E.F. Schumacker

well, many countries give subsidies and other financial incentives to make it profitable (or more profitable)

whereas in the US they give fossil fuel power generation tax breaks.
