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

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.

Kit for sale now- www.berezintechnologies.com blog — http (more info) DIY vertical wind turbine of the Savonius style. Notable is that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy and the generator is a recycled automotive alternator with magnets added). Axle: 3 inch PVC piping from Home Depot Bearings: 5 inch lazy suzan from Lowes. Part 3 will cover connection to the battery bank with charge controller www.berezin.com (My Blog with more info and photos on this and will contain DXF drawings of the gears and other components which can be made manually or with CNC)

Part 2 is now done and covers power generation: www.youtube.com Harness the wind for less than 0. DIY vertical wind turbine of the Savonius style. Notable is that this cost less than 0 in materials so far and that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy). Also, this turns well in a very light wind. Axle: 3 inch PVC piping from Home Depot Bearings: 5 inch lazy suzan from Lowes. Part 2 will cover power generation and connection to the battery bank.
