In the narration he mentions that a 24 speed gear set, or
even more,
would be perfectly feasible. No wires, no cables, either.


I estimate that a New! Innovative! Revolutionary! Better!
bicycle transmission has been invented every two years or so.


I would expect a hypoid gear set in an oil bath to be
relatively efficient compared to a chain. Any ME comments on
an open crown & pinion set?
