Looks promising!
Reserving french translation of ANN when it's posted!
BTW, how are three gears supposed to work in a same plane ?


They are not in the same plane... they are out of this world!

I thought so.

Showing how the blockchain tech disrupts the rules we know so far.
Bit off topic here,
But it reminded me of this guy, who used 3D printing in order to make a 3-gears device possible.
https://www.youtube.com/watch?v=5Mf0JpTI_ggThe CAD surface design to make those work is incredible. Not an easy task to keep the pressure angles on those mechanisms low enough that they don't jam, especially with the rough 3D printed surfaces. Wonder if the models are available for download.
