1930s autogyros had a power take off to spin the rotor up. But I was thinking of a reaction wheel that would be like a stepper motor that could spin up either way. Maybe pairs that can spin with or against each other. Commutator to pass the power in and out.

edit: almost forgot. I'd watched this earlier.
