Hi there,
I started working on an idea for an expandable gear CVT about 3 years ago, while out of work for a few months.
I had some exciting progress on an idea that I think might be worth pursuing more, but I now have 2 kids, 2 jobs, and no time. I have brought up the project idea with a few friends, but they didn't have the time either, or they wasn't interesting enough to them to strain their brain :)
I originally thought of the idea while riding my single speed bicycle, which I like to due the high toque to speed efficiency, but I still wanted to be able to adjust the gear ratio somehow for going up or down hills, of course.
I really like the NuVinci CVT, created by Fallbrook Technologies, just north of me in Cedar Park, TX, I live in Austin. But I suppose I like my idea better, if it works, due to it having a higher speed potential, and for it potentially being the first (I believe) solely mechanically automatic transmission.
Any feedback and/or collaboration on moving forward with this project would be appreciated.
Please see the attached MS Word .docx file, and concept images.
Thank you,
-Michael Warren Reed
