More blades and closer spacing between windmills optimizes power / land area. But what matters is power / capital cost.

He tried to touch on that - making the blades shorter but in greater quantity will drive efficiencies of scale in manufacturing and shipping. And smaller turbines lead to cheaper towers. Hard to know if he's right without crunching actual numbers though.

With land area being one factor that goes into capital cost.
