Okay, but why is everything wind-related so impossibly big? What's the physics behind needing blades so big that they can't fit into a cargo container? Instead of several very large turbines, why not 1000 or 10,000 of them?

Regarding the size x quantity, I believe the reason lies in where the best wind is, which is usually high above the ground. The roughness of the terrain and obstacles generate shear and turbulence, which translates into more stress for the components. The higher wind has a more uniform distribution across the rotor and is higher in magnitude than in lower heights. So for small wind turbines to have access to the best wind, you would have to build expensive structures to reach there, making it infeasible. Hence kite approaches like the one posted and Makani (with different principles).
Higher winds are much more stable. Both in having less completely still days, and having the median be much closer to the maximum. A wind turbine that is built big enough starts having a large part of it outbut be effectively baseload instead of intermittent, and as more renewables are built out, baseload capacity is increasingly more valuable than intermittent.
