The development of the vertical-axis wind turbine (VAWT ... which increases as the plates spin faster. The blades of the generator are made from blue foam with a metal bar running through it ...

We’ve all got a pretty good mental image of the traditional wind-powered generator: essentially a big propeller on a stick. Some might also be familiar with vertical wind turbines, which can ...

In this paper, a method for the determination of the aerodynamic performance characteristics using NACA airfoils is given for three bladed horizontal axis wind turbine. Blade geometry is ... (2006) ...

A wind fence developed by New York-based designer Joe Doucet is set to bring clean energy production into urban landscapes. The fence consists of vertical wind turbines, is modular, and ...

Each arm has a vertical blade, a surface with two waves that change their angle of attack across its height and length. Traditional wind turbines are ... based on the same idea as natural selection.
