Windmill Power of Bangui Wind Farm

Album Info:
(DSC04232) The WIND does not always blow well for the windmills. During hot summer months, power production is at its lowest because there is not enough wind to turn the blades. At zero to 3.5 meters per second wind speed, the windmills generate no electricity. But production peaks during stormy months, when the wind of storms up to signal number two are well absorbed by the blades. The windmills shut down automatically, though, when the wind reaches the maximum of 25 meters per second or 90 kilometers per hour. Also, storms do not necessarily guarantee the turning of the blades. In the olden days, windmills had to be physically oriented so each faced the wind. Today computers do most of the work, requiring minimal human intervention (mostly when a cog malfunctions) to operate and maintain the windmills. The windmills of Bangui, like their European cousins, can on their own face the wind where it is strongest. The system is highly computerized that an engineer in Denmark, home base of the windmill manufacturer Vestas, can control the giants of Bangui. The blades are the most high-tech part of the wind turbines. The blades are made of wood, carbon fiber, and fiberglass, making them light in weight but strong enough to absorb wind power even during storms. The blades tilt to an awkward angle, looking much like a dead starfish, when something breaks down. Each tower has a four-meter wide base, wide enough to accommodate men and equipment and a ladder leading up to the tip of the windmill if human hands are needed to fix a mechanical problem.

That's so interesting. I didn't know the blades change direction, or that they are controlled by remote computer. Again, a gorgeous image, with the colors of the seaweed, the texture of the sand, the incoming rolling wave, the silhouettes of man and machine with beautiful mountains and sky. What more could you want?
