The project Vortex without blade tries to upgrade the current 3-blade wind turbines to bladeless wind turbines. A second generation of wind turbines that can generate the same energy as traditional, but with clear savings in terms of production – operating costs and other environmental benefits – landscaping.
Not long ago we saw a very interesting project with a new concept of wind power generation: The Wind Tree. Quiet turbines for cities.
They are totally wind turbines different from the current ones both in their form and in the way of generating energy. Those responsible for the Vortex project are David Suriol, David Yáñez and Raúl Martín, business partners Deutecno. The simplification of the system allows savings in materials, transport and maintenance which will generate up to 40% more energy with the same euro, more economical and efficient.
In 2006 David Yáñez presented the first patent. Since then, they have not stopped working on this project. They built their own wind tunnel for testing in a garage in Avila, where they even tested a 3-meter prototype. Until this year, Repsol selected the Vortex project for its business incubation process. This will give them the opportunity to transform a laboratory project into a commercial product.
The device consists of a semi-rigid vertical cylinder, anchored in the ground, and which includes piezoelectric materials. Electrical energy is generated by the deformation that these materials undergo when they resonate with the wind. Or as David Suriol puts it in a more familiar way “It’s like putting a baseball bat upside down, upside down, and it rocks.”
It is about taking advantage of the Von Kármán vortex street effect so that the wind turbine oscillates from side to side, so that it is possible to take advantage of the kinetic energy to convert it into electrical energy.
Some of the advantages of these new wind turbines are:
- They do not generate noise.
- They do not interfere with radars.
- Reduced cost of materials and assembly.
- Reduced maintenance costs.
- Reduces environmental impact and landscape impact.
- More efficient. Produces less expensive clean energy.
- It works with a wider range of wind speeds.
- They occupy less area.
- Birds cannot fly around you.
- The carbon footprint is reduced by 40%.
- They are ideal for offshore factories due to their ease of installation and maintenance.
The project Vortex without blade won first prize in the Energy and Industry category in South Summit 2014.
This year, they will complete a pilot installation, a combination with solar power to power homes in India.
They had the initial support of Repsol and twelve private investors. The market price would be around 5,500 euros for a 12.5 m high wind turbine. But the goal is to build a 100-meter Vortex by 2018. The higher it is, the better its performance!
David Suriol himself explains in just under a minute what the Vortex Project is, what are its benefits and where they want to go:
