Increasing the efficiency of the conversion of electricity into light energy (UV LEDs) has made possible a new stage in the development of vertical axis wind turbines by compensating for the small wind energy conversion efficiency (14. 81%). The work is based on the use of Taguchi methods (TM) in increasing the efficiency of a wind turbine with vertical axis blades made of deformed al... https://www.homehardware4ues.shop/product-category/mirror/
