I wish I tossed in $1000.00 when they were at $0.04 :P

wow... 24 combustion chambers... 24 combustions per revolution... id give it try.

42hp out of a motor that is 6x6 in engine is pretty impresive

making decent emissions and mileage is a whole other ball game

lol is it wrong that when i watched that video i skipped to a 3 rotor movie, then a 4 rotor, then to various car videos, then to running from the cop videos...i spent a good hour and a half watching about 23425 videos lol

it looks like it would be more efficient than the renesis.

emissions might be something else.

Six apex seals too many for you? How about 48 with this monster? Frictional losses must be astounding. Proper lubrication seems like a daunting engineering problem.

The Wankel concept is elegant, this seems too contrived. I'll believe it when I see it in commercial production.

That thing has more seals than a circus!

Twenty-four little combustion chambers, twelve sliding vanes, yards of friction surfaces and terrible internal stresses - doesn't look like a winner to me.

Notice how the combustion pushes sideways on the vanes - they won't last. Also a lot of friction on the end cams/caps.

You beat me to it, Mr. Tull!

The biggest weakness I see in this thing it that is transmits power via a cantilevered (and sliding, none the less!) vane. That alone will limit the amount of power that can feasibly be achieved with this concept. Think of it, why only 6" diameter to make 42 hp? Scaling it larger will maginify the frictional forces exponentially. The problem is not sliding surfaces in general, but loaded sliding surfaces that kill. And with the cantilevered vane, this thing would load the hell out of those sliding surfaces!

This design is actually the most feasible of the "other" rotary conecpts that I've seen: LINK

Heating issues

I'd be concerned with the heating issues on those vanes. So much power, so little space.

that **** is huge, but as alot of people said, that is just.......too much seals, defeats the part of being a rotary

Many many people base their opinions on theory. I look at this like a archetype and hope for more

That's what everybody body said about the original rotary. You never know, may take a few years but it may have a shot.
