VORTEX BLADELESS

Market position

The company operates in renewable energy and small-scale wind, with data providers tagging it across renewable energy, smart buildings and green building verticals and keywords such as bladeless wind turbine, vortex-induced vibration, distributed energy, urban wind energy and off-grid power. It explicitly targets segments poorly served by larger-scale wind power rather than the utility wind turbine market, and is compared by one data provider with other small-wind companies including Windcredible, Airturb and Eolic Wall. A Wikipedia article on the company carries maintenance notices regarding promotional content and notability.

The generator has no blades, gears or lubricants and no moving parts in contact, which the company associates with reduced maintenance and operating cost, silent operation, lower risk to birds, and simpler and safer installation than rotary machines. It is claimed to use fewer raw materials and have a smaller carbon footprint than a rotary turbine of the same height, and a low centre of gravity permitting smaller foundations. Very low wake turbulence is said to allow several units in the area occupied by one rotary turbine. The company positions the technology as sharing building materials, grid compatibility, operating conditions and energy conversion method with conventional wind power while differing in underlying physics.

Technology

The generator is a vortex-induced vibration resonant device rather than a horizontal- or vertical-axis rotary turbine. A fiberglass and carbon fibre reinforced polymer mast, fixed to an anchored base and acting as a cantilever, oscillates through the emission of von Kármán vortices as wind passes the slender structure. A carbon fibre rod at the base drives a linear alternator with neodymium magnets whose stator sits inside the moving part, converting mechanical energy to electricity without contacting moving parts, gears, oils or lubricants. The alternator damps oscillation and can shift the structure's natural frequency via a patented magnetic-repulsion tuning system, extending the lock-in range and sustaining resonance at higher wind speeds by altering the apparent elasticity constant with oscillation amplitude. Six registered patent families cover the design.

Go-to-market

The company describes itself as a Spanish startup in the middle of a long development and production journey, aiming to offer a wind alternative spanning consumer-level installations to large wind parks. In practice it states it does not aim to compete with the wind turbine industry but to serve the end-consumer market and low-power systems as a small wind alternative, positioning units to work alongside solar panels for off-grid, residential and rural use.

End consumers and low-power system users: off-grid locations, small-scale residential and rural autonomous installations, and distributed generation on buildings and factories, often deployed alongside solar panels.

Geography

Spain, with locations cited in Madrid and Ávila; a private-market profile lists Madrid as headquarters.

History

The venture was formalised in 2012 by David Yáñez, David Suriol and Raúl Martín, and the founders moved to it full-time in 2014, the year cited as the official founding of the firm. The underlying idea is traced back to 2002. Grant and public-funding activity is recorded from 2012 onward, with crowdfunding and an equity round in 2015, a further grant in 2016, and accelerator participation in early 2021 associated with Techstars. Investors listed on a private-market data profile include Techstars, the European Commission, Spain's Center for Technological Development and Innovation, Equinor Ventures and the Repsol Foundation.

Risks & controversies

The company remains at development and prototype stage for its product line, with commercial availability targets stated for 2021 and stages described as pre-production or projected; its small-and-medium-enterprise status was cited as limiting it to small wind alternative devices. Several technical claims in third-party encyclopedic coverage are flagged as uncited, and that article carries notices about promotional content and questionable notability.
