The turbine was tested in the French laboratories of the National Institute for the Exploitation of Marine Resources. Its particular variable geometry makes it ideal to take advantage of any turbulent water stream.
With no dams or large infrastructure, the WindCity turbine uses the variable geometry of water flows to produce clean energy.
WindCity’s hydrokinetic turbine is ready for water baptism. The prototype, a 25 kW unit capable of producing hydroelectric power using any current, was first tested two weeks ago in Boulougne-sur-Mer, in the laboratories of Ifremer, the French National Institute for the Exploitation of Marine Resources.
Submerged in a tank three meters wide and two meters deep, the unit has been subjected to artificial waves of up to 1.5 meters per second, a power that replicates that of the ocean.
This made it possible to check the potential of the so-called passive variable geometry: in fact, the Windcity turbine, unlike traditional hydrokinetic devices with fixed geometry, is capable of adjusting itself, adapting to changes in water flow rates without the need for human intervention.
Based on the natural shape of the currents, this type of technology broadens the field of application and also makes it possible to take advantage of the energy of rivers without dams or large infrastructures.
Impressed by the innovative scope of the device, the French researchers decided to give Windcity the opportunity for a second week of testing in January 2020: “ Testing the turbine in a state-of-the-art ocean laboratory is impressive, because it forces you, as an inventor, to face the disruptive force of water, “said Tommaso Morbiato, founder of the startup.
In addition to the great technological innovation in terms of clean energy production with minimal environmental impact, the smart wind turbine applications seem revolutionary in the perspective of the circular economy.
In fact, it can be used, for example, in the context of the efficiency of wastewater treatment plants, where industrial, canal and coastal wastewater could be exploited thanks to this turbine to produce electricity.
