Re: Rotors "powered by the wind"
It's neither powered by the wind, nor lifted by it. "Wind" is defined as a movement of the air, whether naturally or artificially generated. Gyros and fixed-wing aircraft fly by hurling themselves through the air. This creates relative airflow past the aircraft, but it's not "wind".
A gyro is powered by its engine which drives it forward, generating airflow over the rotor and making it spin. The spinning rotor generates lift and the gyro slips the surly bonds of Earth. Kites are powered by the wind, and cannot fly without it.
