• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Check out this cool and very unusual motor...

Odd... The cylinder and piston completely seperate, then come back together... There would have to be some tight tolerances on that sum-bitch... And I don't see how the cylinder/piston stay parrallel while it's spinning, but then again, I didn't invent it. Neat concept!

there is a vid of it running and model showing how the gears keep it in line. It works.
 
That's something special, would love to see if it has any power advantages over the normal IC engine, i reckon that will have a nice torque curve too.
 
Interesting, but doesn't it seem like you would be wasting energy by moving the mass of both the cylinders and the pistons?
 
great concept! The video that shows it running was interesting. A lot of parts but no battery,radiators & other things would be very different. Sounded loud! But probably depends where the mic was
 
Not to be a buzz kill, as the concept looks and sounds revolutionary and wonderful... just like a perpetual motion machine.

It also doesn't have any sort of an exhaust system/muffler.

the exhaust vents right into the engine case which in this example has no cover installed. Notice there is also no oil? Ceramic pistons and cylinders and no contact mean almost no friction / heat other than the combustion itself. Very interesting.
 
Somewhat like the WWI invention of a machine gun firing through the propeller (but I´d be slightly apprehensive about flying in the aircraft and pressing the "fire" button).

No oil? yea ...
 
I'm failing to see an output shaft. With the installation of all those permanent magnets; it very much seems to be a generator for use of electric motors. A very promising 'hybrid' solution.

And the amount of rotating mass is huge. And how do you deliver the fuel with everything rotating around like that? Seems like an overly complex, inefficient design, although being so different, it's kinda cool.

Read about it. There is many things it does not have like a cooling system, oil, way less frictional loss as the cylinder and piston do not touch / no side loading and there is no reciprocating (up and down) motion to deal with.. and other things. Also it fires 2 times per rotation not once per 2 rotation (like a normal 4 st) so it turns way slower but produces more power. I would say it is way less complex and should be efficient (they say 50% more but who knows) Not sure how fuel is delivered but it runs so it is.
