Another improvement on conventional wind turbines: this year, scientists from Kyushu University found a way to not only triple the electrical output of a wind turbine, but also decrease its noise level and reduce the risks to avian populations, simply by using a “wind lens” in place of traditional turbine blades.
In the works since around 2007, airborne wind turbines would take advantage of the consistency and higher speeds of high-altitude air currents. There are a number of companies researching different models of airborne wind turbines, including Joby Energy, Makani Power, Sky WindPower and Magenn Power.
In 2010, scientists from Cornell University developed wind power installations small (and cheap) enough to place on your roof, so called “vibro-wind panels.” They work by converting vibrations from even the “gentlest of breezes” into electricity.
in 2009, scientists from Purdue University developed turbine blades that can quickly change shape and adapt to wind conditions to help maximize the amount of electricity generated while ensuring longer life spans for wind turbines.
Canadian company VBINE Energy has commercialized the Vertical Axis Wind Turbine (VAWT), which can be installed in more urban and industrial settings. The VAWT is a ring-shaped generator that can encircle any cylinder and rotate around the structure with the aid of wind-catching blades.
