Burned wind turbine near Magdeburg (Germany)
Last Sunday (27.10.2013), close to Magdeburg (Germany) one wind turbine has burned. It is supposed that the reason was wind gust. It is said that the generator was overheated.

Floating Offshore Wind Turbines
Power targets the rapidly maturing offshore wind sector by eliminating current deep-water limitations with an innovative and economic solution.WindFloat is a floating support structure for offshore wind turbines with a simple, economic and patented design. The innovative features of the WindFloat dampen wave and turbine induced motion, enabling wind turbines to be sited in previously inaccessible locations where water depth exceeds 50 m and wind resources are superior. Further, economic efficiency...

Mitsubishi 7 MW Wind Turbine Blade
This is really a competition!! The companies are trying to do their bests. The next amazing news are from Mitsubishi. They have pronounced the 81.6 meters blade was developed at Euros' production facility on the island of Rügen, Germany. It has a mass of 32.5 tons!! It will be tested in Glasgow, UK and Fukushima, Japan.

Wind Cube-Wind Turbine for Wall
What a creative wind turbine design !! ''Wind cube'' is a modularized wind power system designed for the lifestyle in cities. The concept is to use 3D wind fields to make up the insufficiency of 2D ones. At that point, this new wind cube design differs from the other ones.
Wind cube
The part which is called as nacelle is rotating also to wind direction. The modern turbines has only one certain position for wind(tilt and cones angle), that's why the new design can capture much more power...

Bladeless Wind Turbine
The new wind turbine concept provides cheaper and more efficient wind energy. This is called bladeless wind turbine which is more economic and environmentally friendly than existing wind turbines which produce lots of noise and kills birds.

Siemens 75 m Wind Turbine Blade( World's longest )
Day by day wind industry is going to be massive. The next incredible new is from Siemens. They're building the world's largest turbine with each blade 75 meters in length. Each blade is made by carbon fiber(Siemens believes the B75 blade is the world’s largest fiberglass component to be moulded in one piece.), and it will be working at coast of Britain in 2014.

During 20 Years Generating Wind Power
20 years ago on 14 May 1993, nine onshore wind turbines along the harbor wall at Blyth in Northumberland started to produce power. These 9 onshore wind turbines were the pioneers. Between them they produced less electricity than just one of the modern turbines now springing up in the North East countryside.

20 years ago they were really giants, but when we look today's new generation offshore wind turbines one must say these 9 onshore wind turbines...

Vestas V100-1.8 MW
Vestas V100-1.8 MW have 49 m blades which are designed to extract much more power from the low winds. Thanks to 100m rotor diameter, it maximize the power output. What's more it is starting to produce power just at 3 m/s which is pretty low wind speed. That's why as a summary one can say, for lower wind sites, V100-1.8 MW is a good choice.
Vestas V-100 1.8 MW
Many times Vestas V100-1.8 MW is tested and as consequence it is reliable. Since 1999 6500 Vestas 2 MW turbines are installed...

Ice Effects on Wind Turbines
Wind turbines should be able to work really in hard conditions. Sometimes they must withstand so cold weathers, sometimes so high temperatures which depends on where the turbine locates.

Especially the blades are effected in an important manner from the cold weather. And sometimes the ices can be problem for wind turbines. That's why during development state, up to climate conditions of desired area which turbine will be located, some extra calculations...

Windspiral Wind Turbines
Day by day the number of vertical axis wind turbines growing. Because they are more efficient, easy to install, smaller, and most important one cheaper to build than the common wind turbine designs.
Windspiral Turbine
One of these interesting design is Windspiral turbine which is roughly 10 meters long ant 1 meter width. As the others it is also used for converting wind energy into measurable electrical energy. It has same working principle with vertical axis wind turbines. And it is remote...

Wind Turbine Blade Tests
Blade tests
If we look up to the wind turbine costs. It can be clearly seen that the blades have a huge importance for a wind turbine. Blades are used for capturing energy from the wind. Longer blades mean higher captured power. But when the blade length is increased, beside higher power, higher loads will also occur. After certain wind speed blades won't be able to withstand with higher loads and they will be broken which is not desirable situation. That's why the blade length is optimized.

Why do wind turbines always have three blades?
If you have seen a wind farm, you have noticed that wind turbines have 3 blades. Why not 1 blade, 2 blades, 4 blades or 5 blades ? Because the aim is when the power is produced not to capture more wind. The aim is capturing wind with greatest efficiency. And as a result it is found that 3 blades is the most efficient and less troublesome way.
Wind turbine with one blade
It is not common but when you see a wind turbine with one blade, you shouldn't surprise. It looks like a little different...

Wind Turbines with Solar Panel
Wind turbine with solar panel
Creative idea !! Wind turbine with solar panel. Working principle is a little bit different from the other ones. Solar energy is used for producing power instead of using wind energy. Whats more the energy from small solar panel is used for rotating the blades. It is just for fun. As it seen this is a wind turbine model for kinds, offices or houses.

Sometimes different types of designs can be seen as the following photo. The energy...
