In the dim reaches of my mind I can remember a little physics. I think that there may be an issue with the way the current is generated through the rotation of magnets and orientation of the wiring. If the ei module is placed inside the magnetic field in some of the older “spinning magnet” type arrangements and it’s orientation is aligned with the magnetic field then I suspect you may not get a working system because one will effectively suppress the other unless the shielding is very very good.
