Vortex Bladeless uses a radically new approach to capture wind energy. Our device captures the energy of vorticity, an aerodynamic effect that has plagued structural engineers and architects for ages (vortex shedding effect). As the wind bypasses a fixed structure, its flow changes and generates a cyclical pattern of vortices. Once these forces are strong enough, the fixed structure starts oscillating, may enter into resonance with the lateral forces of the wind, and even collapse.
Instead of avoiding this aerodynamic instability, our technology maximises the resulting oscillation and captures that energy. Naturally, the design of such a device is completely different to a traditional turbine. Instead of the usual tower, nacelle and blades, our device has a fixed mast, a power generator and a hollow, lightweight and semi-rigid fiber glass cylinder on top.
Our wind generator does not have any moving parts in contact, which eliminates the need for lubrication and reduces wear and tear. Also, it’s known that a structure can only have a certain frequency of oscillation, which limits the number of working hours. However, thanks to a self-tuning magnetic coupling system, Vortex can operate in a wider range of wind speeds.
Our technology has two main advantages over the traditional wind turbine: we are cheaper, and more environmentally friendly (noise absence and no oil required for maintenance).
To demonstrate the feasibility of the technology, we have tested dozens of prototypes in wind tunnel, and we are currently doing field tests of complete small-scale equipment.
