Sorry if it has been discussed previously, the LB search engine found nothing.

It seems a very interesting concept - but as yet no evidence it run on fuel and no patent??
How could such a small output shaft handle 813ft/lbs of torque too??
I just cant help being wary of claims like these.
the problems i see are the tips of the rotors wearing, just like a rotary engine, and also they dont explain what makes the two rotor sets move
differently, i belive that starting and stopping them could waste a lot of power/effort. Would be nice to see a working model though!
in that second video, he says it produces 800lbft of torque at 800rpm. If you bear the gearing in mind, thats not that good...

I would like to see one running on fuel for an extended period. He claims to have run one on biofuel but there is no video of the run. It is a very
elegant design and 'theoretically' feasible. I am concerned that he states that the only friction losses are in the 'piston'
rings. The close tolerences required to prevent gases escaping between the rotors that the pistons are mounted on would produce some drag due to
lubricant viscosity surely.
I am not convinced but him just pushing it around with compressed air.
Very impressive concept though.
Comp raio of 20:1 with American pump gas? Surely that'll just blow up!
American pump gas? Surely you mean cat urine. 
Yup, that's pretty much what I meant! 
American beer and fuel, both are pretty close to water!
Seen the design somewhere before, probably mentioned on here. The claims are certainly very high, would be interesting to see an independant test.
