Hello ES!
Probably not a new idea, but here goes...
The concept is to take the down tube, bottom bracket, etc. and re-think it as a power module, merging human and electric power sources. Another variation on StokeMonkey, Cyclone, and j3tch1u's Mag Max, influenced heavily by the RC stuff and Recumpense's multi-stage reduction drives.
Design goals:
1) Modularity: If 10 or 100 are built, can they be used as prime movers in a variety of bikes?
2) Practicality: Can it be built without dozens of custom parts?
3) Performance: Keep the weight low and central. Minimize unsprung weight in the wheels.
4) Economy: Building the e-drive components into frame components means I'm getting double-duty out of high strength/stiffness components, vice adding in strong (~= heavy) stiffeners strictly for the e-drive
5) Flexibility: Bike should work well in pedal only mode. It should work well in e-drive only mode.
Implementation:
Here's a picture of what I have in mind:
