Yeah, that's more or less what I was getting at, albeit in less detail. Put topography and how it interacts with the wind and all of that under the category of "mechanics", I guess? But, in the simulation that this study is based on, it looked to me like they assumed flat terrain and laminar airflow coming into the field of turbines. Which I'm assuming happens in nature approximately never. So it's like, sure, maybe this turbine arrangement can get 15% greater power output under ideal conditions, but I don't think you can get from there to, "this is a clear win over the incumbent technology" anywhere near as easily as you could in the case of an photovoltaic efficiency improvement.
