And... It's a two stroke

That is fascinating indeed. One can easily see that engine design in a hybrid, bringing down the cost and weight of charging the battery.

The company has quite an impressive list of names.

Very interesting. Won't ever have to worry about valves impacting pistons and the opposing pistons should cancel out most of the vibration. Also, the opposing pistons effectively gives the engine a longer stroke while reducing the central rotating mass. I'd like to see the dyno graph on this thing. Would be interesting how much torque it produces in both diesel and gas form. You can even see the piston cooling oil jet. I bet this thing is loud.

I like that the top piston's power stroke is pulling on the connecting rod and the bottom is pushing. With that, the opposing set of pistons are coming together with the force of the opposites power-stroke.

I wonder if it will be like a rotary where you can add sets of cylinders...twin cylinder=four stokes...four cylinder=eight stokes...or the killer six cylinder=twelve strokes!

I would absolutely love to see and hear this thing run.
