Wind turbines are only growing bigger as their demand increases, but how big can they get? Learn the answer in our informative guide.
Utilities managers use wind tunnels to test wind turbines used to generate electricity. Wind tunnels help make the turbines and their blades more efficient, effective and durable, so they can withstand constant, powerful gusts. But wind tunnels also help engineers determine wind farm layouts and ...
Anemometers are used to monitor the safety of tall structures, control wind turbines, and to guide ships. They are used at most weather stations – from the Arctic through to desert regions. That’s because wind speed can indicate a change in weather patterns. For example, an approaching sto...

“Son, you can be anything you want really to be if you just believe.”She told him not to depend on others, including his mother. “You have to earn success, ”she said. “All the people who work hard don’t succeed, but the only people who do succeed are those who work hard....
angled to cope with varying wind speeds.Some designs use vertical turbines (垂直涡轮机), which don't need to be turned to face the wind.The towers are tall, to get the propellors as high as possible, up to where the wind is stronger.This means that the land beneath can still be used...
allowing you to consult the time in three different time zones at a glance. I first met John McConnico at the Windup Watch Fair in San Francisco. Standing tall amongst them will be Peter Bol, his sights fixed unwaveringly on securing victory in the Games’ 800 metres. It is one of onl...

Structural Improvements for Tall Buildings under Wind Loads: Comparative Study Adding to this stability, the tower has a swinging steel pendulum, called a "tuned mass damper", which stops the top of the tower wobbling. Indian-origin sculptor behind the iconic London Olympic tower A sheared tuned...
For high-rise buildings and other slender structures, such as wind turbines, towers, and masts, the dominant mode is likely the first (or fundamental) vibration mode. An effective system reduction procedure must isolate the targeted vibration mode, referred to below as mode number s, while ...
