Safety

Can wind turbines kill if they shed ice?

Are wind turbines shut down when there is a build-up of snow or ice on their blades that rotate at the end of the blade at around some 150 mph and shed ice some distance?

Well the wind lobby says they do. Don't trust them! See this YouTube video of rotating blades with ice build-up.

Accidents

Here are some photos of what happens when transmission failures occur in windmills.  To date no gear oil has been invented to withstand the pressures produced within these transmissions.  Most recently, the government gave Dow-Corning a big grant to work on it.  Previously, many others had tried and failed.
