You could always do something like this :)

Paul, The problem with that drawing is that
too many people are mechanically ignorant and
to them that drawing LOOKS feasible! Bill Jepson

I must reply that I am NOT mechancally ignorant, and that method
of power extraction WILL work , and I challange you  to explain why it
will not. A planetary reduction is certainly easier, but this system will
extract power at 1/3 eccentric speed with the comenserate 3 times
the torque for the same HP. the path of the U joint is the same as the
rotor.
and may be balanced in the same way. The power of the rotary is
produced by pressure area terms on the rotor. If you "grab" any rotating
element in an engine you can extract all the power from that element,
just as some Continentals drove the prop off the cam shaft. I think if
you really study that drawing, and review the operation of the Wankel,
you will have to agree. Vance Jaqua - graduate engineer with almost
50 years of experience in the design and analysis of aerospace
propulsion systems.

It looks like you are getting torque Vance :)

You need to explain what you are going to do with the e-shaft.
Does it rotate or stand still? If it rotates what are the loads
on the phasing gears? What happens if you extract power from
the e-shaft? Also your drawing showed two rotors and 
obviously the second rotor does not enter into the power generation 
in this mode.

Speaking of torque as I recall you wrote an article for alternative
engines called something like lets "Torque about Horsepower.
If you don't mind I would like to OCR it and publish it
with credit to you of course every time the subject of
torque verses HP come up again.
