Pedal power

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.
