I think two rotors running in opposite directions on the setup your talking about might work very well.

 This is great work, interesting notice -Efficiency of Rotor with Eccentric Mass with Small or Greater Speeds!
I would like to read more of your work!

I don't get it. How can an eccentric rotor provide energy just by its rotation?

These will give you a better idea, Milkovik also explains it in some his videos. It has to do with conservation of angular momentum and elliptical orbits. Here is some more good reading;

Not clear at all what he's doing there, let alone why should there be an effect. He's driving the motor with external energy and is measuring the torque, is that it?
