The Freiezo Vertical Axis Wind Turbines


Pictured are the prototypes of the Freiezo Vertical Axis Wind Turbines (VAWT).The focus of this proposal is the little unit on the far right. It is the plastic prototype used in the wind tunnel tests at St. Louis University’s testing laboratory.




Usually the VAWT is utilized in the vertical or upright position as shown in the picture to the left.



But let’s consider the VAWT being at different angles as the horizontal position on the left.

The next step is to attach air intake venting to the wind turbine to “scoop up” or "siphon off" the air as the unit is moving.

Shown left is an example of how these Air Intake Generators might be utilized on a semi tractor trailer in these concept drawings.

But lets extrapolate out the various other uses and functions of the Air Intake Generators

Air Dam or Airfoil on Automobile

Attach an underbody air dam or airfoil containing the AIGs to the front of an automobile.


Spoiler or Deflector on Automobile

Attach a spoiler or deflector containing AIGs to the rear of an automobile.

Internal Grill Mounted on Automobile

Attach AIGs behind the grill and underneath the radiator of an automobile.

While the Air Intake Generator System may not provide complete charging to Electric and Hybrid Vehicles they will provide additional mileage between charges to increase the range of the electric and hybrid vehicles.


Advantages of the Air Intake Generators:

  • Increases range of EVs between charges.
  • Easy to install and attach.
  • Economically viable.
  •  Environmentally friendly.


Thank you for your time and consideration.
