Although, alternative technology needs not incoporate breakthrough principles into its design, new wind turbines are proving that innovation can indeed revolutionize the past. Spanish researchers are designing windmills with efficiency far greater than any horizontal axis windmill of old. One of the key advantages of this design is that the blades are located in the front rotation area and in the direction of the wind, and offer practically no resistance when blades are cycling through the generator’s return area. This allows the machine to harness available wind more efficiently. Read more.
