WindStor ANNOUNCES FILING OF PATENT APPLICATION

FARMINGTON HILLS , MICHIGAN -May 31, 2006— McKenzie Bay International Ltd.'s ( MKBY.OTCBB ) subsidiary WindStor Power Co. (WindStor) announced today that a patent application has been filed for design improvements to the WindStor wind turbine.

“While the optimization process took longer than we expected, we are absolutely delighted with the results” stated Gregory N. Bakeman, McKenzie Bay International, Ltd. President. “Because WindStor’s improvements address many of the disadvantages of current vertical axis wind generation turbines, we believe the new design represents the next generation in turbine design.”

The optimization process, led by Analytical Design Service Corp., located in Ann Arbor, Michigan, has been designed to result in a more rigid, lighter and more efficient wind turbine. The state of the art tower (shown in the simulation to the right) has been designed with a center tube as a structural member, which extends to the top of the turbine cage to increase rigidity. The hub, to which the lower portion of the blades are attached, is also the shell of the direct drive generator resulting in fewer parts aloft and less mechanical loss of energy.

The primary improvement is the elevation of the blades to the top of the tower with an improved hub and attachment assembly designed to improve performance and streamline maintenance . With the blade placement at the top of a tower, WindStor’s turbine is designed to take maximum advantage of its omni-directional power generation capacities.

The turbine is designed to rotate at a maximum speed of 50 rpm and reach its rated power output of 200 kW at wind speeds of 12m/s (26.84 mph). The lower rotational speed is expected to reduce potential harm to avian species and to be virtually silent when operating. The device is expected to produce approximately 500,000 kWh per year in average wind speeds of 7m/s (15.66 mph).

WindStor® is a wind energy system designed to generate and distribute electricity at urban and off-grid facilities with a "WindStor® Vertical Axis Wind Turbine" and a proprietary "System Integrator." WindStor® is owned by WindStor Power Co., a wholly owned subsidiary of McKenzie Bay International, Ltd. Additional information about WindStor® can be found at www.mckenziebay.com.
