winfin concept
With the burgeoning interest in going green, new concepts in power generation, energy conservation, and energy independence seem to be everywhere. However, not many of them have the potential of the WINFIN, a revolutionary and inexpensive small independent wind turbine energy system capable of eliminating or reducing home or commercial utility bills.
Wind energy captured by the WINFIN can be used immediately, sold through the power grid, or used to operate remote energy applications. It is designed to be environmentally safer and less costly than energy created by other types of wind turbines. WINFIN’s specially designed airfoils and innovative continuous adjustment system allow it to rotate several times faster than the prevailing wind.
Have you ever asked yourself, ‘How does a sailboat move faster than the wind?’
When a sailboat is moving in the same direction as the wind, the sails merely trap the wind and move the boat along at the same speed as
the wind. When the sails are properly angled into the wind, "lift" is created. Properly harnessed, this lifting capability can be used to generate
energy several times stronger than the original wind speed.
WINFIN takes advantage of "lift" to accelerate rotation and generate more power.
The WINFIN prototype has demonstrated the ability to multiply the power of the wind and achieve a rotation seven times faster than the
speed of the wind powering it. Based on field trials the inventors have conducted with the prototype, and using a common generator, the
prototype generated 5 kilowatts at 22 miles per hour (mph) wind speed. This is enough electricity to
power a typical household.
No need to shut down generation during high winds.
Wind speeds exceeding 40 mph have been shown to have less effect on the operation of the WINFIN prototype than on other types of wind
turbines. The system operates at a lower efficiency, but it is still generating power when many conventional systems must be shut down.
A virtually silent system makes a good neighbor.
One of the biggest issues with wind turbine systems is the low-frequency noise they generate. The WINFIN design is virtually silent, making
it a good neighbor regardless of where it’s operating.
Affordability gives WINFIN an edge over existing systems.
The simplicity of the WINFIN design suggests that lower material and manufacturing costs may be achievable. The inventors estimate that
the initial cost for a production unit with 3-5 kilowatt output will be about $8,000. In addition, return on investment with a WINFIN system is
predicted to be less than five years; payback with a comparable conventional system can be as long as 10 to 15 years.
Imagine the possibilities that improved wind energy generation could mean to millions of homeowners, farmers, ranchers, commercial businesses and municipalities -- not to mention what it would mean to our country and the planet.

Malco D2 Group Involvement
The Malco Design & Deliver Group is proud to have been involved in the WINFIN prototype project. Our role consisted of working with the inventors from the earliest stages of the project through the completion of a full-size prototype. Dan Christian and Don Anderson worked with The Malco Design & Deliver Group to shape and define the scope of their project. We took their vision and created a computer-generated concept for how the WinFin might be configured. After careful analysis of the performance requirements, strength needs, and physical properties we developed a preliminary design that minimized weight, mmized strength, spun efficiently, and was within budget. We then built a prototype that could be taken to the field for testing.
We are pleased to report that their prototype has performed very well in field tests and is doing its intended job of proving the viability of the WinFin concept.
