“Vertical Axis Wind Turbine” “Wind Gin” Short Version
By
“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.

True Free energy devices exist,But the Establishment doesn’t want ppl to know this,Get a motor that works with the power of magnets only at LT-MAGNET-MOTORdotCOM ,Join the revolution!

Free Energy is real but the coverup is strong, if you are interested in a REAL free energy machine then
just search for the LT MAGNET MOTOR in the youtube video search , it is probably the ONLY working magnet
motor out there. Join the free energy revolution!!

Interesting idea but if you have a windmill with vertical blades, they will spin no matter the orientation, and also reduce the need for moving parts, which could potentially fail.
Still, I think you did a great job on the design.

Please take a look at my FAVORITES section to see similar designs. My objective is to promote alternative energy and my videos may be published on any web site. Thank You

I would appreciate your help in promoting these concepts. Thanks in advance.

Bottom Line: I think a leverage system will beat a propeller system in low wind conditions and I would like to see someone take on the project in a serious way. My videos may be published on any web site.

Leverage type designs might also find a niche on a smaller scale. Examples; Small Farms, High Rise Buildings and etc.

Possible improvements:
(1) Simplify the tower to a tripod type design.
(2) Increase the arm length and reduce the stack height.
(3) Counter rotating stacks.
(4) Autonomous computer control.

The basic objectives:
(1) Design a leverage system that would provide more power at lower speeds.
(2) Design a VAWT that would operate at the same heights as HAWTs.
(3) Design a method for stopping the turbine when desired.
(4) Promote alternative energy innovation.

Wind speed can mean a large difference in available energy and in electricity produced, and therefore, a large difference in the cost of the electricity generated. Also, there is little energy to be harvested at very low wind speeds (6-mph winds contain less than one-eighth the energy of 12-mph winds).

The following excerpt explains the relationship between the standard wind turbine and wind speed. This is why I have attempted to design a low speed wind turbine along with the fact that many areas do not meet the average wind speed requirements.

Thanks! About nine years ago I built a rough prototype of the J1 design. The experiment proved out the basic mechanics and leverage potential but I lost interest because of time and money. A few years ago, I started learning CAD and decided to attempt the concept in 3D. I knew it would have a wild look but I decided to do it anyway. I think the design is simple but I certainly understand that others may see it as too complex. I do think the design could be simplified a good bit.

Love your work. Keep it up.

ha, kewl! Would be sweet to see one like this the size of a skyscrapper!

Good idea. Too much friction though…

pretty cool idea nice job
