A composite material based on a continuous basalt fiber is used in the manufacturing of vertical wind turbine blades (VAWT – Vertical Axis Wind Turbines). The produced blades are light, flexible but much stronger than metal or plastic ones. Moreover, the composite material is both resistant to the adverse factors and environmentally friendly.
According to the developers, when installed by minor energy consumers (houses, shops, street lighting) and also by industrial enterprises, the wind turbines perform equally well.
A basic model for domestic use provides a single-family house with electricity even in the absence of the sunshine and the wind for three consecutive days. A few 5 kW generators can easily cover the requirements in electricity of a 12-storey residential building. There is another advantage of such a system – it is actually noiseless operation.
A vertical wind turbine is equipped with solar panels, resulting in possible 20-25% increase of solar panels power generation compared with non-hybrid solar panels. In addition, electricity in the hybrid system is generated 24 hours a day.
Furthermore, the special design enables this source of renewable energy to be easily assembled in almost any part of the globe.
Nowadays the vertical wind turbines are used all over the world by both individual people and local authorities (for street lighting). There is such a wind turbine in Russia.
The structure is so lightweight that it is possible to install it on supermarket roofs, high-rise buildings, street lighting poles, bridges. The VAWT patent owner is Smart Industries Inc., the company which promotes vertical wind turbines in the USA, Europe, Central and South Africa. Jiangsu NewHope Renewable Energy Company performs the same function in China.
