Bladeless wind turbines swing to generate electricity
David Yanez, the co-founder of the start-up company Vortex Bladeless, is the inventor of the bladeless wind turbine, a slender, vertical simple machine that oscillates instead of rotating or rotating, but collects the kinetic energy of the wind.
He said that it can convert energy into electricity at a cost of about 30% of the cost of traditional wind energy.
Janez said: “What we want is to find a niche market that traditional wind power cannot cover properly,” standing next to a swinging 2.75-meter bladeless prototype in the countryside near Avila, Spain, where there is no vortex. The location of the blade. according to.
“Niche… what we see may be [the] The small wind energy industry, because it requires no maintenance, no oil, and low cost, this may be the factor that makes this idea a useful tool for distributing energy and producing energy close to the point of consumption. ”
Yanez, as an engineering student in 2012, watched a video of the collapse of the Tacoma Strait Bridge in Washington State in 1940. He got the inspiration for his invention by observing how the ill-fated bridge oscillated in the storm.
Vortex Bladeless was born around 2015. Since then, Yanez and his team have been working on the development of bladeless turbines, hoping to commercialize them.
Since then, their original design has been developed, and currently, they are using prototypes with dimensions of 2.75 meters and 85 cm, which are intended to be used in urban centers.
Vortex bladeless wind turbines can be used alone or in combination with solar panels.
In the daytime and the wind is not strong, solar panels can provide energy. Yanez explained that at night, when the wind speeds up, bladeless wind turbines may step in to provide energy around the clock.
Yaniz said: “For those urban centers that do not have the solar energy resources of Spain and the entire Mediterranean region, the urban environment seems to fit this idea perfectly.”
He said that compared with traditional wind turbines, it also produces no noise and does not require much maintenance.
CEO Rodrigo Ruperz said the company’s current prototypes are also useful in more remote environments.
Ruperz said in a speech at the University of Salamanca: “We believe that so far, there has not been a niche market developed.” The University of Salamanca installed a small 85 cm on the roof of one of the buildings. prototype.
Will not rust due to moisture or salt
In the long run, Yanez’s hope is that his invention can be used in the offshore wind power industry.
He said: “The advantage of this technology is that it does not have elements that will rust due to moisture or salt. Perhaps this space may be the most suitable.”
Currently, Vortex Bladeless has five patent families internationally. Yanez estimates that with the right investors, they can commercialize its prototype within 12 to 18 months.
Previous bladeless wind turbine designs include Electrostatic wind energy converter at Delft University in the Netherlands with Wind Fruit “Wind Tree” of French New World Wind Company.
