Bladeless wind turbines save more than 500,000 birds annually


A Spanish company develops wind turbines that do not require blades to generate power, but unlike conventional wind turbines, which use breeze to spin the blades to power a generator, it uses a turbine Vortex Bladeless Motion caused by air crashing into its 10-foot-high tower generating power, as well as being much quieter and smaller, can save Vortex Lives of up to 500,000 birds that are killed by conventional turbines.

According to the British newspaper “Daily Mail”, at the present time, the device can generate only a small amount of energy, but the developers hope to increase the energy and provide it to dozens of homes with one device.

Wind turbines are an increasingly popular choice for environmentally friendly energy, with a smaller carbon footprint than coal or natural gas, but with enormous blades spinning at speeds of over 200 miles per hour, they pose a serious threat to wildlife, killing hundreds of thousands of birds and bats each Year.

In the US alone, blades are responsible for between 140,000 and 500,000 deaths, according to the US Fish and Wildlife Service.

But the Madrid-based company has developed bladeless turbines that can generate electricity without sacrificing space or wildlife.

The blade-free vortex turbine design takes advantage of the aerodynamic phenomenon that occurs when air collides with a solid object, to harness the wind’s energy.

Two rings of centrifugal magnets are placed at the base of a 10-foot-long tower, and when the breeze pushes the pylon in one direction, one of the magnets pulls it in the other direction, providing a strong impulse, even when wind speeds are low, and these movements are converted into electricity using an alternator. That increases its frequency.
