Vortex bladeless turbines wobble to generate energy

Up to 80 percent more cost effective to maintain –  supposedly has a greater than 50 percent manufacturing cost advantage and a 40 percent reduction in its carbon footprint compared to standard wind turbines

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

Designed to reduce the visual and aural impact of traditional spinning-blade turbines, this new device takes advantage of the power contained in swirling vortices of air.

Many opponents of spinning wind turbines point to their supposed danger to birds and other flying animals, as well as their rather noisy operation and – particularly in commercial installations – their enormous size. Though these may well be excuses by those who prefer to stay with older electricity generating technologies that they know and trust, standard wind-driven turbines do have these issues and this tends to hold back their universal acceptance and use.

This is where the creators of the Vortex bladeless believe that their device has the advantage. A relatively compact unit, it relies on the oscillation of its reed-like mast in reaction to air vortices to move a series of magnets located in the joint near its base to generate electricity.

Though obviously not as efficient as a high-speed, directly wind-driven turbine, this is offset by the fact that the Vortex has fewer moving parts and is, according to the creators, up to 80 percent more cost effective to maintain. Coupled to the notion that it supposedly has a greater than 50 percent manufacturing cost advantage and a 40 percent reduction in its carbon footprint compared to standard wind turbines, the system also seems to offer direct economic advantages.
