This first article is interesting in its description of the design,
prototyping and analysis. I have no idea if the engine has merit but it
seems to have some new wrinkles.
I wonder if anyone on the list is using Autodesk Inventor. To quote
them "The Autodesk® Inventor® product line provides a comprehensiveand
flexible set of software for 3D mechanical design, product simulation,
tooling creation, and design communication that help you
cost-effectively take advantage of a Digital Prototyping workflow to
design and build better products in less time.

Of course, to quote The Preacher: The thing that hath been, it /is that/
which shall be; and that which is done /is/ that which shall be done:
and /there is/ no new /thing/ under the sun.

Yeah sure 100 MPG.
Looks like another stock scam.

Regarding their claim:

- 100+ MPG?s
  - 180 ft lbs Torque
  - 200 Horse Power


I ride a motorized bicycle with an 66 cc swept volume 2-cycle engine:

- 100 mpg (measured and true at 25 mph average); vehicle + passenger = 300 lbs

- 4.5 ft-lbs torque

- 2 hp (1500 watts at 5000 rpm)


Now you can better separate fact from fiction.
