So today, most turbines are well over 100 meters tall, with equally large rotor diameters. A turbine of this height and size can capture a huge amount of wind, generating enough electricity every year to power 750 American homes. A wind farm of...
When you are asking yourself: "How tall do I have to be to dunk?" - you are asking the wrong question! Wingspan is also very important as it is a big part of the standing reach. If you have a vertical jump of 100cm you will be spending more than 50% of the hang time above...

As early as 3000 B.C., people used wind energy for the first time in the form of sail boats in Egypt. Sails captured the energy in wind to pull a boat across the water. The earliest windmills, used to grind grain, came about either in 2000 B.C. in ancient Babylon or 200 B.C. ...
All sorts of machines use turbines, from jet engines to hydroelectric power plants and from diesel railroad locomotives to windmills. Even a child's toy windmill is a simple form of turbine.The huge rotor blades on the front of a wind turbine are the "turbine" part. The blades have a ...
Even with aerodynamic blades and a horizontalrotor, a wind turbine can only capture wind if it's in a windy environment. Wind speeds typically increase the higher into the atmosphere you travel. So today, most turbines are well over 100 meters tall, with equally large rotor diameters. A turb...
Wind turbines – which we could define as "the windmills of the 21st century" – are fascinating machines that harness the power of the wind to move their blades, which then turn the generator that produces electricity. We’ll explain in five simple steps how they convert this natural resourc...
This exercise is another one of the explosive movements. Allkettlebell workoutsshould contain these kinds of movements. Take the kettlebell from the floor to a tall position in one go, using the shoulder muscles to stabilize the kettlebell overhead. ...
From sailboats to windmills, humans have been putting the kinetic energy of wind to work for thousands of years. The mechanics behind modern wind turbines are more sophisticated, but many of the basic principles remain. Utility-scale electricity generation installations use Horizontal Axis Wind Turbine...
Many countries around the world are using wind power to harness nature for local human benefit. People who drive by them often wonder how wind turbines work. The rotation of these gigantic windmills creates electricity, and this renewable energy is added to the power grid. ...
