A new method boosts wind farms’ energy output, without new equipment

This is a really good question. The reason regular turbines and wind turbines are designed differently is because regular turbines have a small volume of fluid experiencing a large change in pressure while wind turbines have a large volume of fluid experiencing a small change in pressure. You see the exact same thing in fans - big ceiling fans look like wind turbines and air compressors look a lot like regular turbines.

I’m sure the cost of a casing plays into it, but its primarily about the energy efficiency of different blade shapes in different hydraulic conditions.

And if it were more efficient, there’s the the challenge of rotating the casing when the wind direction changes.

I mean the whole point of the casing as I understand it is to contain a flow at above ambient pressure - not something that even makes sense for wind. You could have different (more turbine-like) blade geometry without a casing.
