our website www.mwands.com I’am demonstrating our new 3 phase brake switch and 3 phase rectifier combo designed by Missouri Wind And Solar. Also our all in one wind and solar charge controller board with inverter and dump load for wind turbines. At the end of the video i show our latest digital amp, volt meter, easy install. Thanks for watching. Jeff, MWAS

Vertical Axis Disk Wind Turbine

How the turbine works: Rotatable shutters mounted on a circular disk automatically open when directed into the wind, irregardless of the wind’s direction. Pairs of upper and lower shutters are geared together. The lower shutter acts as a counterweight to the upper shutter. The bottom shutter opens in the downward direction and its weight helps to lift the upper shutter in the upward direction, as the wind applies an opening force against both shutters. When the shutters reach the vertical position, stops prevent them from opening further and the force of the wind is transferred from the open shutters to the circular disk. And the circular disk is attached to the vertical axis for power output. The circular disk, shutters, and outer vertical axis rotate together. The outer vertical axis is mounted via bearings over an inner vertical axis that is stationery. The shutters are blown closed by the wind (no stops in the opposite direction) as they reverse direction during their rotation and move into the wind on the opposite side of the wind turbine. When the wind is not blowing, the shutters open by gravity because the lower shutter is weighted to be slightly heavier than the upper shutter and it therefore can cause the upper shutter to open via the force of gravity as the two shutters are geared together. Wind blows against the open shutters and the open shutters with stops apply a force against the disk, but the open shutters with no stops (opposite side going into the wind

We are currently seeking investors, and manufacturing companies to license, purchase patent rights, or enter into a royalty agreement for this, and our other inventions from “DW”- the inventors of this innovative new product. When you think about it, almost every great advance in medicine, art, engineering, politics, religion, design, and RULES FOR THINKING, in general, has occured when people challenged the previous rules of thought and tried a new approach. Here’s a unique inexpensive use for bamboo to make a vertical windmill. This is a new “spin” for bamboo! Let’s get this inexpensive vertical wind turbine product producing power in India, Africa, Asia, and other tropical bamboo growth areas globally. (pp) The power output can be adjusted to suit the given resource of wind currents from any direction. We have a solar photovoltaic componet add-on at high speed rotation as a hybrid energy additive for storage or kick laucnhing the “first motions”! (rotational inertia) It is said that fully 70% of the economy in areas of India come from bamboo products. Here’s one that produces energy & money long after it’s built. In addition, solar cells have been shown to last 25 years or more, so the additional high rpm solar umbrella on top, is a must! With this VAWT, ALL WINDS ARE ACCEPTED FROM ALL DIRECTIONS! (no tail fin needed) Also, this VAWT has easy, low to the ground maintenance, –and cheap materials & as always, it’s “cost per watt” to the bottem $$$$$$- line. To capture a

www.Regenedyne.com Demo CGI for proposed 2GW Magnetic Leviatated wind Turbine. *Efficient Frictionless Power Generation with less maintenance, compared to HAWT. No oil change or replacement of the bearings, gears. Since, MAGLEV does NOT require such. ** Current bearing technology has forced wind turbine designers into horizontal spindle three bladed wind turbines. In this design the huge blades are connected to a spindle in the center. The bearings that support the spindle and control the pitch of the blades (which can be hundreds of feet long) see huge pitch-moment loading, some of which is manifest as torque energy that is focused through the center spindle. The target speed for the spindle is 18 or 20 rpm and the bearings holding the spindle are mounted in a huge casting which also contains a large gearbox stepping the speed up to 1800 to 2000 RPMs which allows for the proper surface speed relationship between the coils and magnets. It is necessary to invert or condition the current, which is expensive. This gearbox is full of many large bearings, gears and castings; for a 2 MW turbine the gearbox can easily weigh 30 tons. This gearbox needs to be mounted on the top of a pole more than 150 feet in the air and be able to support the turbine blades under full-force wind conditions. ***MAGLEV Power Generation, the pitch moment ratio is closer to 1-to-1 then the 100-to-1 as with a horizontal spindle design.
