Click on the "English" button on the left.

The company claims it's a revolutionary six-stroke rotary engine.
120hp, 60lbs. Are they kidding me or what?


I'm not sure, but I want to give you the benefit of the doubt and assume
that is a redundant question?

Look at what they are proposing. A long sliding vane in a tight slot.
This sliding vane composes one entire side of the combustion chamber.
Can you imagine the side load placed on that cantilevered beam? How
thick would the vane have to be to not bend under such loads? And now
that you've made it thicker (and heavier), what are you going to make
the sidewalls out of to withstand the centifugal loads and sliding
friction? And now it has to slide in and out of slot while loaded.
Ever tried to put a side load and a beam and slide it in a slot? And did
you look at the steep curve in the sidewall that will force the vane in?
Is there any doubt in your mind that the vane will simply be sheared off?

They're not trying to kid anyone. Either they are totally honest, and
completely ignorant of what the inside of an engineering class looks
like, or they are looking to scam some venture capitalist.

mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
