A vehicle with a bladed rotor mechanically connected to the wheels can be designed to go at a speed faster than that of the wind, both directly into the wind and directly downwind. Upwind, the rotor works as a wind turbine driving the wheels. Downwind, it works as a propeller, driven by the wheels. In both cases, power comes from the difference ...

This effect becomes more severe with the reduction of the number of blades. The most common passive yaw systems are: Roller Bearing (free system): The nacelle is mounted on a roller bearing and it is free to rotate towards any direction. The necessary moment comes from a tail fin or the rotor (downwind wind turbines)
Counter-rotating wind turbines Light pole wind turbine. Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2024, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.
Sailing downwind, the apparent wind decreases the more the ship speeds up and at exactly the true wind speed, would drop to zero, so that the wind turbine can generate no power and also no thrust if used in the autogyro mode. Therefor windmill ships are limited to less than wind speed when travelling directly downwind, as with other sailing craft.

The yaw system is located between the wind turbine nacelle and tower. The yaw drive is an important component of the horizontal axis wind turbines ' yaw system . To ensure the wind turbine is producing the maximal amount of electric energy at all times, the yaw drive is used to keep the rotor facing into the wind as the wind direction changes.
