WOW, look at this engine

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

Actually, the answer to that question is helpfully provided in their
FAQ, question 5, "What will consultants probably say when I ask them
about the Green Engine?" With answer "They will say we are smoking
crack."

Well, actually, their answer is a bit more long-winded:

There is an engineering phenomenon that most all consultants disagree
with each other, and there is a great deal of prejudice or competition
between any of the various technologies. (I.E. Turbine specialists
discount piston technology and vice versa). Furthermore, few
consultants will give a positive report on any technology they are not
directly involved with because of liability. Also, any consultant has a
limited expertise dependent on their actual "hands on" experience, and
outside experts can only get very limited basic information about a new
technology which is being under development (Normally the most
important technology would never be showed by owner). It seems that you
ask a steam engine expert for questions about the jet engine.

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.

This is by far the hardest lesson about freedom. It goes against
instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."

If you're interested in something along these lines, check out the
Rand-Cam engine. I believe the Rand-Cam has actually run.
