So someones read the hows things work on CV T's . While CV T's can be and are if well made more efficient then regular transmissions in order to make a efficient one many calculations are needed. Refer to Paul's white paper. Keep in mind as well that the design you have shown requires three motors or two servos and a motor if you wanted to use servos for the rotation of the inner disc's a lot to invest in one gearbox at least in my opinion. All I am saying is this is no cakewalk to produce something like this that is efficient.

I was interested so I added my comments after some research,
