A wind conversion unit is provided with a central shaft having one or more channels extending through the shaft perpendicular to the longitudinal axis thereof. A blade unit having a spoon shaped blade with a concave face is secured at opposite ends of each channel to direct airflow through the channel and receive airflow from the channel. The concave faces of the blades on opposite sides of the shaft are oppositely oriented so that the concave face of one blade receives an airstream, directs the airstream through the restricted channel which then impinges the airstream on the concave face of the opposite blade. A velocity modulator driven by the shaft applies centrifugal force and gravity to a flowable material to compensate for changes in airflow velocity and force. |
