> Vertical turbines far more efficient when in large-scale wind farms than they are individually
The article is saying that in large-scale wind farms, vertical turbines are more efficient than horizontal axis wind turbines (the "traditional form factor").
With horizontal axis turbines in large wind farms, there is always a loss of efficiency through the "wake effect" where some of the turbines are downwind from the others.
But the study seems to have found that this can actually increase the efficiency of vertical turbines. Which is very unexpected.
