This was presented to me as new - actually goes back a while..
The Hungarian connection is interesting - Hypoid gears came from Trbojevich - also connected with Hungary - a nephew of
Nikola Tesla .
I'm not sure - seems like if this was used on high load this would bring us back to the why we have 'roller bearings'
that replaced 'ball-bearings' to avoid the high point load. (Could play with the ball size..)

Sure would like to see new patent they are talking about.. just can't find it.. seems like I saw a fancy u-joint that
was related.

It's an interesting idea, but they don't seem to explain how the balls
are recirculated. (If, indeed, they need to).
I found one animation: https://youtu.be/C4QCM2yyU-4
I experimented in CAD with a ball worm some time ago. The original
idea was developed, rather alarmingly, by a urology department.

That recirculates the balls through an internal path in the worm,
which is rather elegant.
That looks like sort of the opposite of a ball-screw-nut -
Anyway - I thought some on the list that might have dumped the balls out of a
ball screw might appreciate this.
