Title
(EN) WIND-POWERED ENERGY PRODUCING SYSTEM
(FR) SYSTEME DE PRODUCTION D'ENERGIE A PARTIR DU VENT
Abstract
(EN)
A wind-powered energy producing system comprises wind turbines, generators and a cylindrical hollow wind tower. One or more heat jet devices arranged at intervals of one or more input openings are provided at the lower part of the wind tower. From every said input opening is outwardly extended an input tube in which the wind turbine is mounted. The heat jet devices can be replaced by heating wires provided on the bottom inside the tower. With this system higher efficiency and lower cost can be gained.
(FR)
Un système de production d'énergie alimenté par le vent comporte des éoliennes, des générateurs et une tour à vent cylindrique et creuse. Un ou plusieurs dispositifs à jet de chaleur disposés à des intervalles correspondant à des ouvertures d'admission, sont prévus au niveau de la partie inférieure de la tour à vent. Un tube d'admission dans lequel l'éolienne est montée s'étend vers l'extérieur de chaque ouverture d'admission. Les dispositifs à jet de chaleur peuvent être remplacés par des fils chauffants prévus dans le fond de la tour. Ce système est plus efficace et plus économique.
