The thread above has generated some interesting discussions. See, for example, @aokholm’s arguments, including:
Seems that the visualized design suffer at least 3 of the suggested disadvantages with conventional 3 bladed designs.
Extreme Bending Moments: (In so far that the airfoils generate useful lift). Parasitic Drag: The blade roots that generates no lift, acting primarily as a drag penalty. Fatigue & Gearbox Failures: Predictable torque spikes that severely damage conventional PTO systems.
I will suggest try designing a conventional 3 bladed turbine with the same power production capacity before believing the novel concept is better.
These arguments can be a counterpoint to Michael Bergey’s “nope”.
There is also quite a few ‘nope’ about other projects based on vertical axis wind turbines (VAWT), and an AWES, but I couldn’t find the direct links.
