US Patent 8487463 Enhanced multi-mode power generation system

An enhanced multi-mode power generation system harnesses solar energy, wind, and heat within a designed building or within a large enclosed area, providing an indoor system to generate electricity. Air within an enclosure is heated, either by solar energy or by use of an electrified exothermic heating material, to enhance the airflow velocity within the enclosure. A system of narrowed passageways within the enclosure further increases the airflow velocity, which enhancement may also include or be supplemented by a blower. The enhanced velocity air is passed through one or multiple-staged wind turbines to generate electrical power.
