And, the guy's only an assistant professor. :') Decades ago, there were a couple of diesel engine designs which never caught on, both were bent in the center, and the rotation of the halves produced the compression. They were mirror images of a sort -- one had the 120° pistons in the middle, the other one had the 120° cylinders in the middle.

It's more usual for ideas of this kind -- good or bad -- to languish.

Thanks Ernest.

A similar design has been used for 40 myears as a hydraulic rotary servo for heavy equipment.
