Magnetic Harmonic Drive System!

This is true.  However, you wrongly impied they used lighter parts by design to reduce the inertial mass of the rotating members.  Eliminating the inertial mass of the rotating members equates into a quicker response time, higher acceleration rates, and a higher COP while maintaining the high torques associated with the conventional mechanical harmonic drives.
 
This almost qualifies as a complete solid state harmonic drive, and you downplayed it by keeping it fully in the mechanical realm by suggesting the use of lighter mechanical parts to reduce the inertial mass of the rotating members by design!

No, really what I was after before going into any depth was whether you thought the document was telling the world that their inertia reduction you highlighted was a matter of design versus an extraordinary claim or reducing inertia by some process during operation.  There are people out there who believe in such things.  If that had been what you were claiming then that claim would have been the center of conversation.  I try to keep things simple and direct.  I don't always succeed.

MarkE,

Do you think a solid state contactless variable gear reducer should be the center of conversation?  Such as, a hybrid harmonic drive combining the magnetic contactless reducer from the video of the OP and a rotating electromagnetic wave generator from the unclassified document.

It's a way to make a CVT.  When it was first invented, somebody thought it had enough military application advantages to classify it. 

Do you want to talk about applying it to something?  Do you want to talk about the principles of operation?

I know you can't be this gullible.  Leonardo da Vinci, in 1490, conceptualized a stepless continuously variable transmission.  Milton Reeves invented a variable speed transmission for saw milling in 1879, which he applied to his first car in 1896.  I assure you that the technology that came out of the once classified CVT program is much more highly advanced than any modern publicly known CVT of today.

A good example of this is Apollo 11's FIBER OPTIC LIE.  NASA used fibre optics inside the lunar TV camera, which they falsely claimed had a primitive vidicon tube ( https://www.youtube.com/watch?v=eGP0vgQBqUs )!  Here's Document 28-105 that discloses the use of a classified and still confidential fiber optics inside the camera case:  ( http://www.hq.nasa.gov/alsj/MSC-SESD-28-105.pdf )

In other words, the classified fibre optics used by NASA in the 1960's is much more advanced than the fibre optic technology being offered to the general public of today.  They used a 'vortex fiber' to carry twisted light in order to increase the rate at which information can be sent along the optical fibre and to increase the bandwidth capacity.

The same magnetic transmission is used widely on industrial inkjet printers. This system separate and seal the ink compartment from the motor compartment. Convenient when the ink consist of methyl ethyl keton.
