This is not our video. Some kind of development from Romania.
As the developers say (automatic translation into English):
The design is a system (two rows) of rectangular blades (flat plate), the axes of which divide them into two unequal parts, the larger of which is always (due to the action of the flow) located behind the axis further downstream.
The axes of the blades, with their upper and lower parts, are, in turn, fixed to the upper and lower chains closed in rings (or to any other flexible element).
The chains transmit force through sprockets (impellers) to two vertical shafts, from which the mechanical energy of the moving medium (water, air, etc.) is transmitted through a flexible coupling and intermediate shaft to the shafts of electric generators.
The designers state that:
1. Behind the turbine, the water has a speed 2-3 times greater than the flow entering the turbine.
2. Behind the turbine, the water level drops (exactly how much is not specified).
3. A few meters down from the turbine, a certain stable water vortex appears.
4. The power that such a hydraulic station produces is 2-3 times higher than a conventional free-flow turbine of the same size.
I would like to start by discussing how real this is and is it possible?
