Tech startup Vortex Bladeless has developed a bladeless turbine that generates electricity by oscillating within wind range.
The 10ft tall vibrating turbine is said to create noise at a frequency that is virtually undetectable to humans and according to Vortex Bladeless, does not pose the same dangers as wind turbines which can be a threat to bird migration patterns or wildlife.
Vortex technology uses no blades nor does it rotate, getting energy from wind through oscillation without gears, brakes nor oil.
The design of the Vortex Bladeless wind turbine is quite different from a traditional turbine. Instead of the usual tower, nacelle and blades, the device has only a mast made of lightweight materials over a base. This reduces the usage of raw materials and the need for a deeper foundation, according to the Spanish tech startup.
The Vortex Bladeless wind turbine is based on the phenomenon of aeroelastic resonance, this way the device oscillates with a quiet non-aggressive movement which makes it perfect to be placed anywhere without disturbing wildlife.
The environmentally friendly aerogenerator is a new wind energy technology specially designed for on-site generation in residential areas, being able to work on-grid, off-grid, or along with regular solar panels or other generators.
The idea behind Vortex wind turbine is that it is possible that same forces can be utilised to produce energy. When the wind vortices match the natural frequency of the device’s structure it begins resonating, hence oscillating, so the bladeless wind turbine can harness energy from that movement as a regular generator.
Vortex Bladeless came in to being in 2012 after founder David Yáñez watched a video of the Tacoma Narrow’s bridge oscillating in the wind. According to David Yáñez, the benefits of the Vortex Bladeless are that it reduces “its environmental impact, its visual impact, and the cost of operating and maintaining the turbine.”
Vortex Bladeless’s design recently won the approval of Norway’s state energy company, Equinor, who will offer the startup development support through its tech accelerator programme.
