The most important thing in wind energy is whether your device is working every day. Thid is the most basic of the concepts in wind energy - your system has to actually “work”. I know, I know, too much for most people here to grasp. The reason we make them is to provide needed energy every day or at least whenever the wind blows. Even a system making 10 Watts in daily operation is better than a supposed 100-kW system that never runs. Supposed “academics” can pretend to analyze their hypothetical models and ideas to death, and it will never make a difference. “How many angels can dance on the head of a pin?”
