It is for a generator. They plan to use it in plug-in hybrids. It will run at a constant speed at it's most efficient RPM.

That’s what I thought when I looked at it. It would never work for direct drive since the fuel mixture is affected by centrifugal force. It would have a sweet spot of maximum efficiency RPM. Above that the efficiency rapidly deteriorates.
