Re: has anyone seen this?
I'm sure it could be made to work! Revo probably has a working prototype of some sort. The red flag for me was the website...it just has that classic "reel in the investors" look to it. There are a lot of computer generated renderings on the site. Some of the ones that look like photos are not.
Unless I missed something...The exploded view on the "design" page doesn't show enough to fully understand how it works. From what I see it appears that engine and all rotates wth the wheel. It looks like the wheel and housing are all one piece. There are missing pieces to the puzzle...which may have been left out intentionally...but if it's patented why not show it all. It would have been better to show nothing.
I may have jumped the gun on this one, but then again I'm in a business where this type of stuff comes up all the time!
