REACHING FOR THE SKY.

The article discusses the history and construction of wind turbines to process grains and pump water. It states that the first to exploit the power of the wind is the early sailors and by around 100 A.D., Heron, a Greek mathematician and engineer devised a wind-driven wheel to power an organ in ancient Alexandria. It mentions that the wind turbines serves as the largest rotating structures in the world. It notes the complexity of building a wind turbine as there is a need for engineers to integrate aerodynamics, structural dynamics, and material fatigue with gear boxes.
