Empirical Investigation Study of Impeller Wind Turbine

Tikrit Journal of Engineering Sciences
According to the latest research, renewable energies currently take precedence because they used to make up 1% of the global energy supply but now account for a higher amount. In order to develop a new wind turbine design that is more effective than existing designs, the inventors were forced to construct a wind turbine.

Clayton Bi-Direction IMPELLER Turbine

The Clayton Bi-Directional Impeller Turbine is a novel wave energy conversion technology developed to replace the Well's turbine in oscillating water column (OWC) applications. Unlike the Well's turbine, which has voids between its blades that allow air to pass through without contributing to energy generation—resulting in an estimated 35-65% loss—the ...
