1. Brushless. Without a doubt. Both for aging and efficiency.
2. Induction motor + some way to bootstrap it in case it is not
magnetized, i.e. smaller synchronous motor.
3. Battery / supercaps. Some form of storage is necessary. Lead-acid
doesn't work indoors. Can it be made with minimal storage?
I.e. keep the energy mostly in "human" form, but allow for catching
breath and changing operators.
