You keep referencing magazine type sites as proof. Well I found a real analysis. https://iopscience.iop.org/article/10.1088/1755-1315/801/1/012019/pdf

Bottom line the projected (a design that has not been built) wattage generated is 1/4 of a vertical turbine design which are available now on Amazon at $349.

One of the reasons I'm so confident this is not going to work is that it has failed in the marketplace, it's been under development since 2014. Even it's wikipedia page is old. Last entry was 2017.

One of the biggest technical shortcoming of this design is that vortex only occurs at a certain wind speed whereas regular turbines increase power out as wind increases. So the vortex has to be tuned to a certain wind speed.

Another problem and this is something I know more than a little about, is that particular type of mechanical energy is difficult to convert to electrical energy. I looked into this because I was curious if they had a novel and clever to convert high frequency, low magnitude energy into electrical. They don't. And this is just one of the problems this design has.

I'm been studying wind generation for 55 years, I hold an engineering degree and an advanced degree in physics.

Data will change my mind. I know never to say never, but that doesn't mean I'm rushing to help crowdsource it.
