SUBSTANCE: solar radiation and vortex wind flow developed inside hollow conical polygonal support. Solar radiation is converted into electric power by stationary conical optically active dome and spinning conical solar battery. Besides, electric power is generated by vortex wind flow developed inside hollow conical polygonal support (PS) to act aerodynamic-shape blades of two three-blade windmills (WDM). Said three-blade WDMs are rigidly fitted on single common shaft inside said PS to run in two parallel planes. Distance between planes of rotation should be not smaller the diameter of said blades. Blades of said WDM located in first parallel plane are shifted through 60 degrees relative to blades of WDM in second parallel plane. All blades feature aerodynamic profile. Aforesaid blades are secured in aluminium rings provided with magnets arranged on outer surfaces of said rings. Magnets poles alternate while coil windings are arranged opposite said poles inside cylindrical section of hollow PS. The number of magnets must not comply with that of coil windings. Vortex airflow inside hollow conical part of PS is developed owing to screw shape of the support faces and temperature difference at inlet of PS conical (confuser) part and outlet (diffuser) part of said support. Air inlet openings are arranged at the base of said PS. Inlet lateral walls ensure the initial swirling of incoming airflow inside said PS. Airflow gets out from said support via rectangular openings located at fop section of said diffuser. Electric power is generated when magnetic force lines cross the winding turns at rotation of WDM blades along with aluminium rings and magnets relative to winding turns under effects of vortex airflow. Electric power generated by tandem photo electronic modules is accumulated in storage batteries. Electronic control unit switches on and off the LED lamps in response to instruction from luminance sensor.
EFFECT: self-contained long-term operation.
