The Windcrank is a unique design that uses proven methods of capturing and controlling energy from any moving force such as wind, water, geothermal, etc. It can be used in a vertical or horizontal application, depending on the end use. These proven methods include, but are not limited to

Centrifugal Force

Deflectors

Louvers

Blade Timing

Sail Effect

Flywheel Effect

Some of the advantages of this design are

Exceptional high torque
Two power take-offs
No bird kill  /  No noise
Stackable applications
No braking required
Multiple applications
Long service life
Controlled rpm's
Slow speed

The application shown on this page is for capturing rotational energy from wind forces. A series of "blades" are "timed" in a specific sequence to capture impulse wind energy. Fixed deflectors are placed on the tip of each blade to boost power and accompany balance weights for a flywheel effect. An auxiliary (moveable) deflector is positioned so as to direct the wind forces to the inside of the blades and divert wind from the back side of the rotating blades. Louvers are incorporated to provide a sail effect for increased turbine efficiency. The auxiliary deflector is also used as a brake to stop rotation of the turbine by directing equal wind forces to both concave and convex sides of the blades. Thus, there is no need for a mechanical braking system and the deflector can also be used to control the rpm's of the turbine.

The patented design (US Patent D300932, other patents pending) won an advanced technology award in Atlanta in May of 1996, where one of the distinguished people on the nominating board was Dr Gordon Gould, inventor of the laser. The design was given a favorable review by the Department of Energy through its NIST 19 program. All current design work is complete, including CAD drawings, for the 4-foot and the 8-foot models. Test data on the 8-foot prototype will be available soon. World-wide marketing and distribution is planned for early next year. Jack Dean, President of VWTT, LLC, is back on the big island of Hawaii now.

The preliminary testing of our 4-foot diameter turbine is complete. Currently, one of our 8-foot diameter units is progressing through its testing process. Test data will enable us to begin production soon.
