Enercon E-126 is The World’s Largest Wind Turbine

24 February 2011 | Wind Power | 1 Comment

A new wind turbine was installed in Emden, Germany: Enercon E-216. It is the largest wind turbine in the world. Maybe you’ve heard about E-112 turbine but this one is even larger. Despite the fact that E-112 is rated at 6 megawatts, this new one will most likely produce 7+megawatts.

After some calculations, Enercon E-216 can produce 20 million kilowatt hours per year, enough to power 5,000 households. Such a turbine produce 11,256 kwh per year per house, so it can power 1776 American homes. German researchers have big plans with their huge turbines. They started to test different storage systems in combination with the multi-megawatt wind turbine.

Wind Gusts Predicting Technology Could Increase Wind Turbines Efficiency

9 December 2010 | Wind Power | No Comments

British firm Quiet Revolution came up with a new method to improve the efficiency of small wind turbines in urban areas. In these places, wind turbines efficiency is frequently affected by buildings that block the wind. In order to prevent those situations researchers have decided to take advantage of those periods when wind reaches its maximum speed.

After many tests, British researchers concluded that they could capture more energy by predicting when gusts of wind will occur. So, in order to capture the maximum amount of energy, they have designed a system called Gust Tracking, able to match wind turbines speed to the wind velocity.

Purple Painted Wind Turbines are Less Dangerous for Bats and Birds

3 November 2010 | Wind Power | No Comments

One of the most important problems of wind turbines is about to be solved. Painting wind turbines in different colors makes them less dangerous for birds and bats.The discovery was made by a team of researchers at Loughborough University in the UK who tested many colors on wind turbines, in order to make them less dangerous for wildlife.

After many experiments they concluded that a purple wind turbine for example, keeps away many birds and bats  from its blades. Now, you may wonder how this thing is possible. Researchers used a very simple concept and I would like to explain it for you.

How to Build a Small-Scale Vertical Axis Wind Turbine

13 July 2010 | Wind Power | 2 Comments

There are many ways to produce free electricity, but one of the most inexpensive ways is to build a vertical axis wind turbine. In this post I will show you how to build a vertical axis wind turbine. After building this small wind turbine you can try to build a large scale wind turbine using same principles. So, let’s stop talking and start working! :)

Choose the Best Wind Turbine Rotor System

16 June 2009 | Wind Power | No Comments

Rotor is the most important part of a wind turbine. The rotor recives the kinetic energy from the wind stream and transforms it into mechanical shaft power. Components of a wind turbine rotor are blades, hub, shaft, bearings and other internals. Blades of the wind turbine have airfoil sections and through it is possible to design the rotor with  a single blade, balancing of such rotors would be a real engineering challenge.Rotors with a single blade run faster and thus create undue vibration and noise. Further, such rotors are not visually acceptable. (more…)
