Here's another prototype
from

Ideally it would come with an 'MGS' system from Ventura watches - a system to produce electrical power for quartz watches (equivalent to an auto winding analogue watch).
I've wondered if Sony licensed the technology from Ventura whether it would be enough to do away with any need to 'plug in' for power for their e-readers - maybe with 2 of the rotors...
