This is the weirdest engine I have ever seen

According to Duke Engineering, their axial engine is the most efficient and lightest engine you can put in boats, light aircrafts, and generators—the mechanical engine of the (near) future! Maybe. I don't know if their claims are true and I don't really care. I just love watching it in action in this eternal gif.

Casey says it is so mesmerizing that it could only be better if it made ice cream.

The final production model of the Duke engine is not finished yet, according to the company:

The design has come a long way since the Duke engine concept was first turned into hardware, yet optimisation of its features has barely begun. Despite this, the Duke engine is favourably comparable to modern conventional designs.

Mechanical and other main characteristics (Seal lubrication, combustion, performance, port timing, port shape, manifold geometry, reciprocating to rotary conversion mechanism etc) are performing satisfactorily at prototype stage, but all will no doubt benefit from concerted R&D effort.
