1.1 Die „NATURFREUNDLICHE, GÜNSTIGE MEHRSTÖCKIGE WKA“ besteht bis auf 300 Meter Höhe, aus über ein andern montierte WKA-en. Die Windventilator-Räder 1, werden vom Wind zum drehen gebracht. Diese drehen die Achsen 2, die durchgeführt sind bis zu die Winkel Getrieben 28, die die Generatoren 27 antreiben. Die Wind-Richtung-Steuerungen 11 bestehen aus Unterstützung-Rohren 12, Kugellager 14, Zahnräder 13, Antrieben 15, und Rollen 17. Diese werden durch die Zahnrädern 13, und Antrieben 15, von den Wind-Richtung-Messgeräten 16, gesteuert, und enden in eine Reduzierung 31, was die Windgeschwindigkeit erhöht. Deswegend kann die WKA auch bei niedrige Windgeschwindigkeit Strom produzieren. Durch 180 Grad drehen von jeden zweiten Windrichtung Steuerung 11, um den Horizontale Achse X, erreichen wir dass jeder zweite Wind-Ventilator-Rad 1, in gegen gesetzte Richtung sich dreht, was zu Erzeugung von gegen gesetzten Kräfte führt. Das ist für die statische Auslegung des Gerüstes 22 vorteilhaft. Auf der Halterung 6, und um den nachfolgenden Windventilator-Räder 1, werden Vogelschutz-Gittern 30 montiert. Die Festplatte 18 ist von einen Gerüst 22, aus Aluminium Rohren unterstützt, die in Beton Fundamenten 23 verankert sind. Zu der Anlage gehört auch ein Fahrstuhl 24.„Diese WKA“ ist direkt auf die Aufstellungs-Ort zu fertigen, kann mehrere heutige Anlagen Ersetzen, ist auf Schwimmende Plattformen aufbau bar, und ist als Offshore Windkraft-Anlage zu Betreiben.
