  • System and methods for wind energy recapture from a non natural wind source
    Patent number: 8939724
    Abstract: The present invention relates to a system and method for harvesting wind energy from air exhausted by other systems. Ventilation and heat exchange systems force air movement using fans. Exhaust airflow may also be the result of a combustion system. The exhaust air is generally wasted as it is diffused back to the atmosphere. Significant energy may be recovered from this exhaust air using relatively small turbines inserted into the airflow. Careful positioning of the turbine maximizes the recovery efficiency.
    Type: Grant

    Date of Patent: January 27, 2015
    Assignee: Green Earth Power Company Limited
