The EPFL researcher is interested in wind turbines with a vertical axis of rotation, whose blades are perpendicular to the ground and rotate around the tower like a carousel, a shape that has earned ...

The vertical axis of rotation means that the blades are constantly changing orientation with respect to the wind. A strong gust increases the angle between air flow and blade, forming a vortex in ...

Wind turbines are considered a vital source of renewable energy but their visible impact on the landscape is not universally admired. Nevertheless, a German company has said that masts must get ...

Wind turbines are a fantastic, cheap, renewable source of energy. However, nothing lasts forever, and over time, the blades of wind turbines fatigue and must be replaced. This then raises the ...

Wind turbines are considered a vital source of renewable energy but their visible impact on the landscape is not universally admired. Nevertheless, a German company has said that masts must get ...

But the very first wind turbines, which were developed ... continuous air flow. The vertical axis of rotation means that the blades are constantly changing orientation with respect to the wind.

This vertical axis wind turbine (VAWT) uses five 3” PVC pipes cut in half for blades rotating on three kids bicycle wheels to spin an Ametek 38 volt motor or a wind blue alternator.The whole ...

Sure, we can those emissions at home, and we are bound to do so by the Paris Accord. But if we embed green energy into the products the world needs as it decarbonises we could reduce global ...

Roula Khalaf, Editor of the FT, selects her favourite stories in this weekly newsletter. Brussels has launched a subsidy investigation into Chinese wind turbine companies as it steps up efforts to ...

If you imagine an industrial wind turbine, you likely picture the windmill design, technically known as a horizontal-axis wind turbine (HAWT). But the very first wind turbines ... The vertical axis of ...
