We are seeking to develop a relationship with those having the interest and resources necessary to create, possibly highly profitable, clean energy in low wind velocity areas.
The Wind Rocker System (WRS) is a patented, clean electricity generation device specifically made to function in low wind environments, yet still generate significantly useful amounts of power for residential or commercial consumption. It utilizes two large sets of sail assemblies and masts that rock back and forth in the wind in time with each other, to deliver steady power input to a common drive axle. As the vertical vane assemblies on one sail close, and it is driven back by the wind, the vane assemblies for the other sail open, allowing its counterweight bucket to stand it back upright. A trigger mechanism linked to this motion helps ensure proper alternating action of the vanes.
This is a drag-force sail configuration, which allows the unit to generate electricity in a lower wind environment than conventional propeller-driven wind turbines. Our current design uses 1200 square-feet of sail area on each mast, which face square into the wind through electronic means via weather vane data input. The opening and closing of each sail's vertical vanes is also controlled electronically by anemometer data input, as well as the opening and closing of its counterpart. Each sail assembly measures 20 feet by 20 feet, and there are three such assemblies on each 75-foot tall mast. A full-scale prototype in a 5 mph wind will produce approximately 24,375 foot-pounds of torque on the unit's main drive axle, which equates to the machine generating 33 kilowatts (KW) of clean electric power.
It is important to bear in mind that a doubling of wind speed equates to a quadrupling of power output. For example, selling this electricity at 6 cents per kilowatt-hour equates to the following earnings potential:
At 5mph wind speed:
At 10mph wind speed:
The ability to produce significant electric power in a low-wind environment will greatly increase the geographic area in which both commercial and residential end use become an economically advantageous market to be tapped. The expected life cycle per unit is 20 years. The Wind Rocker System has many advantages over conventional wind turbines that may not be readily apparent. Aside from its ability to produce power in low winds, it is far more environmentally friendly than any conventional wind turbine:
Because the Wind Rocker System can be manufactured in a portable version, it will have great appeal for use in the following state and federal agencies:
Following prototype tests and validation, additional models can be built for more rigorous testing in harsher environments. Upon a successful completion of these tests, we will then be in a position to develop appropriate strategies for both public good and profitable international manufacture and distribution of Wind Rocker System units.
The international need for clean, fossil fuel-free power is clear. We believe that the Wind Rocker System can be produced and installed at a cost of less than US$ 100,000 per unit. If the market value of power remains at present levels, then conservative economic projections for the entities controlling the Wind Rocker System intellectual property are vast, and a major new industry will result.
Known Sub-scale Prototype Abilities:
In the spring of 2006, a simple sub-scale prototype was built — with a sail height of 4 feet and a total sail area of 12 square-feet — in order to determine the effective power it could produce. The Wind Rocker parameters, and the surprising results achieved, appear below:
The sail had a total area of 12 square-feet, with a centerline height 2 feet above the Wind Rocker axle.
In a 5 mph wind, the Wind Rocker axle easily lifted over 13 pounds.
Using Archimedes’ principle of the fulcrum, this means the 12 square foot sail is effectively “collecting” and concentrating 6.5 pounds of force at its 2-foot centerline height.
In terms of power, this is equivalent to 13 foot-pounds of torque.
Using this empirical data, it is relatively straightforward to extrapolate, by simple scaling, the power a full-scale prototype, — with a sail area of 1200 square feet, and a centerline height of 37.5 feet — could produce.
Since a 12 square-feet sail collects 6.5 pounds of force in a 5mph wind, a 1200 square-foot sail will collect 650 pounds of force.
This 650 pounds of force is concentrated at the full-scale prototype’s sail centerline height of 37.5 feet.
In terms of power, this produces 24,375 foot-pounds of torque at the Wind Rocker axle. This torque is capable of producing 33 kilowatts (KW) of clean electric power. And remember, this only required a 5mph wind!
Because a doubling of wind speed results in a quadrupling of power output, this means that a full-scale prototype would be capable of delivering 132 KW of clean electric power in a 10 mph wind, and 528 KW in a 20 mph wind. When you take into consideration that a modern propeller driven wind turbine requires a minimum wind speed of 8 mph to begin generating any appreciable power at all, the rationale for use of the Wind Rocker System becomes self-evident on many levels.
If one were able to locate Wind Rocker System near a constant 20 mph source of wind, and sell the generated electricity at 6 cents per kilowatt-hour (PKH), one would make $760.32 in a 24-hour period. The extrapolated earnings in a 20 mph wind speed are as follows:
$760.32 per day, $5,322.24 per week, $22,809.60 per month and $276,756.48 per year
With an estimated full-scale Wind Rocker System unit cost of $100K, the initial return on investment is less than 6 months, provided the unit operates in an area with a sustained wind speed of 20 mph, and one is able to sell the power at 6 cents PKH. With a projected working life-span of 20 years, and the many geographic areas of the world where average wind speeds of 20 mph and above prevail, the economic appeal of the Wind Rocker System becomes self-evident. Moreover, it can be quite lucrative for the owners and license holders of the Wind Rocker System patent issued on January 2, 2007 by the U.S. Patent and Trademark Office.
