Vertical axis turbines – the invention of a Polish engineer W. Piskorz, can soon revolutionize the renewable energy market. The turbines, as opposed to the classical wind-powered generators, rotate around a vertical axis and use kinetic energy from the wind. Additionally, they do not create noise.
Advantages of this kind of turbines include, among other things, the fact that the wind speed required for them to work is only 0.6 m/s (a classic turbine – 3-4 m/s), regardless of the wind’s direction; the possibility to be mounted and working in an urbanised area; no environmental impact; unprecedented efficiency over a year’s time (up to 50% higher than classic wind turbines); a positive cost-efficiency ratio; that they can be easily and quickly transported and built; and a general simplicity along with a low cost of technical maintenance.
The turbines are promoted and marketed by the family company of Waldemar Piskorz and ProEnergetyka.
