“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.
Who am I ?
Hi, I’m Erik Astrand and the man behind this site.
My story? I am about to be 50 and all my life I have been interested in technical things. Not sure if the special interest for the wind, and how to use the wind, started when I as a 5 year old boy and got my first sail dinghy.
Anyway, wind power and to build my own wind generator was a dream for several years. I studied many websites and also bought many courses before I finally built my own windmill. This site is about that journey and you will also find some more general articles about wind power.
Enjoy! and check out the about me page to read more.
Hello, I appreciate your interest. This is a concept project and I have no techanical information. Maybe some day a group of engineers will get together and take a serious look at the leverage concept. There are several people that I have listed in my Favorites section that are working on similar ideas.
i love CAD, i learned a bit in highschool.
it is very interesting
very informative for school students like me thanks and keep it up the good work
Well Thank You. Yes it was a lot of work but it was a fun challange.
Yeah, CAD is fun and a great way to use your Imagination. There are some really nice programs out there. I used Autodesk Inventor and Working Model 2D. I have a friend that uses Sketchup and it does a nice job for his purpose. Thanks
I like your idea of wind turbine. Thanks for sharing
Hey, maybe you and a friend could build a small working model for school!
Thanks!
Its really awesome, I’v never seen anything like this..well is it possible to produce sufficient electricity by this wind turbine??
it shows the important of CAD software to build 2D wind simulator
The J3 Model would be a good one to try.
This was a good idea for my son’s school project. I hope you have many other idea. Thanks
Yeah! I like your clip. It’s great
I “think” it would produce sufficient electricity at lower wind speeds due to leverage. Of course, the concept designs I show would all be slow turning, high torque wind turbines and would require a transmission to convert the slow speed back to a sufficient speed for the generator to operate.
One potential advantage of a slow turning system is reduced noise output.
I was thinking that an autonomous computer controlled transmission could adjust the gearing automatically.
very interesting and innovative. new ideas for the development of world electricity
Thank You for your comment. I think there will be several different types of leverage based wind turbine designs. Hopefully there will be low cost models that might come packaged as a kit along with large high end models. Of course, Cost Versus Efficiency will be what determines the success or failure. That is the big challange!
At this point, the low speed leverage concept is still just a concept as far as I can tell. If the required wind speed for wind turbines could be reduced by 4 or 5 MPH, then many more areas of the world could utilize the potential of the wind.
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).
Hey, your concept is sound, is this your idea? I don’t think this simple yet enlightening design does not exist before you.
I would say that if you want to make this turbine starts-up at low speed, then you have to make the blade that turns following the wind direction(pro-wind-direction blades) park at larger angles to the rod. But this will compromise the wind energy loss as the angle gets bigger because the anti-wind-direction blades can catch wind too with significant parking angles..
In fact, this turbine design does not suit for high rotational speed, as the blades need conditioning time to quickly park and catch wind energy. And such, it is advisable to stiffen the shaft(reduce the shaft with gears), make the blades spin slower. Great idea.
@otivaeey I agree. I have many improvements in mind. Thank You
I appreciate your interest. Yes, many concepts shown here are my unique designs but there are several people working with similar ideas which all have unique features. The flap wind turbine is not a new concept but innovators continue to find improvements. Hopefully, there will be several different types that will operate at lower wind speeds and be cost effective.
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
