“VAWT” “Wind Turbine” Feel “free” to use any of these “concepts” in your “windmill” designs. The wing or plate that swings on a vertical rod has been around forever and the rest are just “conceptual designs” that I came up with. An engineer proficient using AVIs stress analysis application could determine structural integrity issues using these drawings. Who knows; maybe someone will perfect this “design concept” and build them to the same height as the large HAWTs. I (think) “Vertical Axis Wind Turbines” have the leverage potential to produce more power at lower wind speeds. I am amazed by the large HAWTs and many of the modern VAWTs but I hope that engineers, innovators and last but not least, financial risk takers will continue to find ways to lower the required wind speed. Constructive comments are welcomed. If you do not have any, Yes We Can! works for me. Thanks for viewing.

Some improptu video of very early design testing of a half-scale impeller model under unfavorable wind conditions. Site has low average wind speeds (less than 5mph; strongest recorded gust 17 mph) and experiences extreme turbulence. Site is actually 12 feet lower than the nearest obstructions (to the north & east). So, this is was a good test for developing usable torque under far from ideal conditions. Dorje Inc is currently developing other impeller designs for medium to high wind conditions. We feel strongly that the impeller should match the site conditions for our installations. Why vertical axis wind turbines (VAWT)? We have many reasons for this choice; some are engineering and performance based, others are ecologically based. VAWT designs are very tolerant of turbulence, and therefore are suited for rooftop installations or other less ideal conditions. They are easier to brake and apply maglev technology to (floating magnetic bearings for axial loads). Also, the design is inherently omnidirectional. Even abrupt changes in wind direction don’t matter at all. But primarly — from an engineering standpoint — VAWT turbines are high-torque, low-RPM systems. Horizontal wind turbines (propeller or fan-blade types) are low-torque and high-RPM systems. With the proper gearing, we can get a lot more power production out of a VAWT system without needing ideal conditions. Horizontals are very finicky about their wind, and an ideal installation places them 30 feet ABOVE the …

www.maglevwindturbine.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.

A breakthrough invention that can be placed IN FRONTof any wind turbine can more than triple the power generated by the turbine. This invention is a specially shaped stator developed in our wind tunnel. It has NO MOVING PARTS, is NOT POWERED, and can be used with EXISTING TURBINES. The stator is shaped in such a way as to create a vacuum as air flows over it. The vacuum draws more air into the the device (in this case a fan), which causes the fan to spin faster. The video proves it works …
