en.Wedoany.com Reported - Austrian clean energy company novventos Clean Energy GmbH has launched a vertical-axis wind turbine named naca.boost, designed specifically for turbulent and variable wind conditions near the ground, suitable for industrial facilities, rooftops, and remote areas. The product underwent three years of research and testing at the company's facility in Neukirchen.
Traditional horizontal-axis wind turbines, optimized for stable high-altitude winds, cannot effectively capture the turbulent, variable, and directionally inconsistent wind energy at ground level. The novventos engineering team conducted hundreds of test cycles on the naca.boost rotor in Neukirchen, iteratively optimizing the aerodynamic geometry. In addition to aerodynamic performance, the device requires no underground cables, substations, or other resource-intensive infrastructure, avoiding land lease commitments and extensive civil engineering work. The system can generate electricity within days of delivery.
The naca.boost incorporates multiple technological innovations. Its lift-drag hybrid rotor design enables aerodynamic airfoil blades to generate lift in addition to drag, extracting more energy at comparable wind speeds. The asymmetric geometry of the wind deflector protects the returning blades from incoming airflow while concentrating and accelerating wind on the advancing side. The vertical-axis configuration allows it to accept wind from any direction without mechanical adjustment, and variable low-altitude winds enhance rotor excitation. The wind deflector integrates six 510 Wp photovoltaic panels, adding solar power generation without increasing the footprint. The device has a noise level of 10 dB at 10 meters and an annual energy production of 10 MWh.
Franz Humer, CEO and co-founder of novventos, stated that the team spent three years of engineering developing the naca.boost, noting that the synergy between wind and solar energy is the real solution. Chief Technology Officer and co-founder Bernhard Fellner said that after years of testing and refinement in laboratories and test sites, the naca.boost has achieved an effective rotor specifically designed for ground-level conditions.
