Looking somewhat like a giant reed gently swaying in the wind, the new Vortexbladeless wind-driven generator prototype produces electricity with very few moving parts, on avery small footprint, and in ...

(Phys.org)—An airplane's vortex generators, which look like small fins on its surface, improve the plane's aerodynamics similar to the way in which the dimples on a golf ball improve the ball's ...

University of New South Wales researchers have created vortex generators that can reportedly reduce the operating solar module temperature by up to 2.5 C. They built two different prototypes, based on ...

Although current climate models brand wind energy as “sustainable energy,” contemporary wind turbine design does not favor wide scale proliferation. Simply put, turbines are extremely noisy, massive, ...

What’s a Red Bull Air Race plane’s stall speed? Red Bull Air Race technical director Jim Reed explains how speed and angle of attack affect lift on a hot lap ...
