Inventors and the invention: The Rolling Fluid Turbine

I am intriguing.
First of all I find the idea very interesting at leat form an academic point of view, and I am more academic rather than engineer. In Engineering, i.e., economically speaking, there must be some comparison with the actual energy which you will get from conventional turbine for energy harvester (including, of course, Wells turbine) before to do the claim of alternative hydro-energy harvester. A conventional turbine is a highly efficient engine (90% or higher).
I will be even more interested in to know, for me, how to avoid the phenomena, because the creation of such eddies should minimize the kinetic energy available, I mean, turbulence means a non adiabatic process and energy is lost. So, How much is the loss power loss by the phenomena?. and what must be done to eliminate the formation of such eddies? , when and how starts to appears? depend of the depth of the pool?. and so on so forth...
But, all in all, I like a lot the idea from Professor Sedlacek and the team and its potential
As regard with some comment from Zybisco regarding the electric cord, it could be the cord you are using to extract the energy from the rotor, which for me is almost sure.

Zybisco, an interesting response, perhaps you may like to visit the website of the company mentioned above and actually purchase one of these 'Baloney' units and see if it is indeed a fake product. Or, perhaps contact the 3 Professors who worked on its design principles, just to clarify your viewpoint?

This is nonsense. The chalkboard schematic says nothing. The fact that they make parts does nothing to support the contention of some high performance extraction of energy from the free stream. The short tank has no way to actually have water flowing in it. There is no visual from any angle of the tank that water is actually moving and finally, the electric cord makes it pretty clear that the "turbine" is running off of an electric motor. I won't even bother to say that the energy calculations have no bearing in actual facts.
No matter what your device does, there is only so much energy in the free stream and converting that depends on slowing down the flow (it's kinetic energy.) And it depends on the cross section. Since you can't stop the flow to extract all of the energy, there is a practical limit. This problem is identical to wind turbines since the flow is incompressible. If this actually worked, every wind turbine would be built this way. No physics, no engineering, lots of baloney.
