Abstract
Systems and methods to generate electrical power through a direct drive wind turbine. In one aspect, the system uses a diffuser cuff surrounding a counter rotating turbine operating inside a streamlined center body, the counter rotating turbine using a generator with an iron sandwich core. The main wind turbine blades are attached to a barrel stave that increases generator efficiency and distributes loading through the tower support structure.
