Hmmm... maybe for railroad, which is already heavier than hell, but for aircraft use I foresee some weight issues.
1. If this uses permanent magnets - those puppies are heavier than hell.
2. If this uses electro-magnets, you now have an engine that's dependent on electrical power. While a back-up battery system is usually available in case the primary (and back-up in this application) generator fails, the power for electro-magnets is going to require a really big battery (heavy current draw for as long as it takes to get on the deck) - which is heavier than hell.

Reminds me of the hype in the Sixties about Sandia Labs’ invention: the Rolamite bearing - “nearly friction free,” “the only simple machine invented in recorded history,” etc.

The only product the bearing was ever used for was a desktop postal scale. I keep one in my office as a reminder to be humble about my own patents.

Can we do away with the timing chain in cars?

If this idea works, we could have continuously variable transmissions for automobiles for a fraction of the current price. It could put an end to manual transmissions for everything except exotic sports cars.

A lot of people have worked on similar systems. Myself included.

Torque transfer is extremely limited with magnetic ‘gears’ before they start slipping, and are directly related to the power of the magnets being used.

Until the advent of room temperature superconductors, the applications will remain extremely specialized.
