Huh?! I don't see this as a viable challenge to the extant business model and they never reveal the numbers, let alone a basic model, behind their "net-zero" marketing claim.

They also still haven't solved the main issue of non-modular turbine blade transport and assembly. Modular and stepped blades are the next frontier. Not tower construction.

Quite frankly, the tower is trivial.

The cost of the tower construction and materials is a small percentage of the initial blade, transmission, and generator assembly costs and on-going maintenance. Even the lubrication flow sensors and lubricants are highly specialized for the unusual duty-cycles and variable loading of a wind turbine.
