Detailed explanation-1: -The “ingenious” O-Wind Turbine designed by UK students Nicolas Orellana and Yaseen Noorani is the winner of the international James Dyson Awards.

Detailed explanation-2: -1* The first wind turbine in the history built by Charles F. Brush. Wind turbines have currently been installed throughout the world, both onshore and offshore, thanks to Charles F. Brush (1849-1929), an American scientist who, in 1887, built what is said to be the first automatic wind turbine to generate electricity.

Detailed explanation-3: -The single-bladed design (Figure 3.4) is the most structurally efficient for the rotor blade, as it has the greatest blade section dimensions with all the installed blade surface area in a single beam. It is normal to shut down (park) wind turbines in very high winds, in order to protect them from damage.

Detailed explanation-4: -The most common odd bladed wind turbine design is that of the three bladed turbine. The power efficiency of a three bladed rotor is slightly above that of a similar sized two bladed rotor and due to the additional blade they can rotate slower reducing wear and tear and noise.

Detailed explanation-5: -There are generally speaking three main types of wind turbines: utility scale, offshore wind, and distributed, or “small” wind.
