Paul, Every time I go to a hot rod or experimental aircraft show, I
 am invariably impressed with the clever thought and ingenuity.   I
 had that feeling again when I came across this "battery replacement"
 proposal.

 If it rotates like a Wankel, sounds like a Wankel and smells like a
 Wankel it is a Wankel. I am surprised the patent office is so stupid
 that they gave them a patent on it.

 A Wankel by any other name is still a Wankel :-)

 Of course it stores more energy per pound than batteries as liquid
 hydro carbons are almost unbeatable in that regard. The only thing
 that comes close is rubber bands. These are pictures of the Rubber
 Bandit. Never flown.

The patent has been applied for, not issued. It's a Wankel with a
generator integrated into the housing, or the eccentric.

Maybe the rotor is a magnet. That might work with aluminium end housings.

I say might because aluminium has magnet properties.

If you have a pendulum with an aluminium disk and you have a
magnet with a slot in it at the bottom of the swing. In other words at Six o’clock.
Now drop the pendulum from three  O-clock and it will stop
at six o’clock. Now cut slots in the disk and it will go right
through the magnet and back and fourth.

I suppose they have tested this device and they are not affected
by magnetic properties of aluminium. Maybe non magnetic SS
will work for the end housings.

Maybe the e-shaft is magnetic and there is an armature  section outside
the engine proper. No different than connecting a generator or alternator
in line.

Cooling the side housings would be a challenge with a magnetic
rotor.

Interesting idea if it works. I wonder what size it is.

The small Wankel engine is not a problem as many Wankel model
airplane engines have been built and sold. They are usually
rather expensive. There is one on Ebay for $410. The Nitto
engine is slightly over one HP or 934 watts at 17,000 RPM.
Trouble is it runs on model airplane fuel with a glow
plug. I'll wager it is LOUD!!! :-)
