Here is my whitepaper:

That is a really cool transmission. I see a potential issue with effeciency, so I would like to ask how well it worked in practice. Here is what I see:
1) The output gears appear to need to slide along the faces of the each other. Were the gears spaced such that they don't rub on each other, or did you just grease them to reduce the friction?
2) The non-engaged gears must rotate freely about the output shaft. Did the non-engaged ball bearings sufficiently reduce the friction between the gears and the shaft?
Just a final question: how was the overall efficiency?
I just want to say that this is really a very cool design that appears to be incredibly space efficient. Good job.
