Same, I like it too, the arguments it brings are very interesting. But some are very questionable, there is a topic on a
forum Quebec who is talking about that (QQOD is me)

Neglecting friction, the forces applied to the rotor all point towards an area too close to the center of the rotor (both the normal housing-> articulation reactions and the resulting pressure-> blades). Under these conditions, how to generate a strong torque on the rotor
the Saint-Hilaires indicate in their book "Quasiturbine, the best of the piston and the turbine" that the thrust is tangential to the stator and in the direction of movement, that it is normal to the surface defined by the joint of contours to the 'front of the piston (or the blade), and to support this, they use the principle of hydrostatic.
Tell me if I'm wrong, but for me, we should also take into account the kinetic energy of the fluid, the principle of hydrostatic applying to immobile fluids.
Considering how the QT is made, and following the principle of hydrostatics, for me, there is also a force in the opposite direction of the movement, on the "follower" contour joints which makes that the resultant of these forces , the thrust is not normal to the contour seal at the front of the blade, does not start from it, and therefore not tangential to the movement ...
In the extreme diamond position, the mediators of two opposite blades do not pass through the center of the rotor.
And each of the chambers is not quite (but almost) symmetrical by the piston mediator, but larger in the front part (front in the direction of the movement), so the thrust does not go through the center and the rotor so is not immobile. (I hope you follow, I have a hard time following myself: cheesy :)
But this chamber being still almost symmetrical in this extreme diamond position, the thrust is directed much more from the center of the rotor than in the direction of the tangent to the rotor of a point of the contour joint. and it's very difficult to imagine having a strong couple
A little later during rotation this room is less symmetrical, the direction of the thrust away from the center, so or could have more torque ...

It would be nice if he gives us his opinion, and his explanation of the thing, but I think it's going to be hard to get to that, considering how he could have taken us down to deflect the problem.
At the beginning, when receiving the Quasiturbine, the usage protocols were almost non-existent, and little by little, by reporting to Saint-Hilaire our questions, our remarks, its "user guide" of the academic kit deepened. . So it's quite inappropriate for him to tell us that we did not follow the usage protocols, and to tell us that our approach to technology was inadequate ...
