I recently completed my first project. I posted it on YouTube today and mentioned Autodesk Inventor a few times because I think it is excellent software. I took an introductory class and after about 3 months I had completed my project to the level I wanted to take it. If you’re interested, you can find the video on YouTube by typing Wind Gin in the search window. The short version is only 2m24s.
Happy Earth Day and Thanks for the help you gave me on this forum.
It reminds me in fact of something I've long thought about - have any of you seen the film Pitch Black?
Granted, it is typical science fiction-fare, with one exception: they have what seem to be solar sails contained within a glass bubble and subsequently tied to a generator.
If the "wings" in your design were made of very thin gold (to keep the weight to an absolute minimum) and the glass bubble contained a vacuum, could these not be made to generate electricity from the light emitted by the sun? (granted, it would probably need some sort of magnetic bearing to reduce friction)
I saw your original post at the time and wondered if your concept was similar to a design I helped refine about ten years ago. Today I looked at your short video on You Tube and would say that it is the same concept as one that was patented by Charles Pratt then of Estes Park, CO. However the patent drawing of his concept is quite crude in my opinion. Your model of the concept is quite refined and very impressive. Keep up the great work. If you are not aware of the patent you might search the uspto.gov site and read the patent.
I appreciate the comments. I’m happy to see some interest here! The videos show the basic concept well enough but the original drawings are much more detailed. I would like to offer my drawings to anyone who is serious about designing a wind turbine that will produce more power at lower wind speeds. I’m not sure how to do this except via mail. You can send me a personal message if you are interested. I also have some general thoughts that go past the drawings. For casual viewers, go to YouTube and type in Wind Gin.
I’m sure an engineer could perform stress analysis and answer many of the basic questions I have and many that I have not thought of.
Regarding patents; I would like to see the patent mentioned. I did a quick and lazy search and did not find it. If you have a patent number or a link, please send it to me. I feel that many refinements would occur if anyone took this to a higher level and then they could decide to patent it or not.
How time flies, it was actually in 1997 when I worked on this. The patent number is 5570997. Below is a link resulting from the search I did using the patent number. For some reason searching on full names on that site does not work very well. I could not even find my own patents using my full name in any combination.
I would like to see the patent of yours that you provided a link for. That was a long address and unfortunately it only brought up a blank screen. I was able to view the text portion of the wind turbine you had worked on but again I could not view the drawings. I'm not sure if the problem is on my end or if special rights are required to view patent drawings and photos.
I'm curious, what ever happened with the wind turbine patent? Was a prototype built? I'm not sure if any serious/expensive prototypes have ever been attempted using a leverage based system like this. Someone probably has but I've never seen it. I was hoping that an experienced Inventor user would take on this project and form some conclusions using the digital prototype method.
The arms which I call struts were intentionally designed short to give the initial stress test a better chance but my hope was that the strut length could be increased to provide more torque. I added some favorites to my YouTube Wind Gin site that shows dramatic stress forces being applied to modern sailplane wings.
Bottom Line; Autodesk Inventor is a great. I was able to take something that only I could imagine and bring it into a moving 3D world for others to draw ideas from.
I think you need to have the Quick Time Player installed to view the drawings/pictures.
I am not sure what testing was done on the prototype for the wind turbine patent. I did have a set of blades fabricated for the inventor and I assembled and shipped them to someone who was supposed to be testing them. I could check into this further if you are interested in knowing more details.
