<p>An air driven fan generator system includes, in association with a fan, a secondary fan, which is mounted coaxially with the fan and with the blades of the secondary fan being relatively closed to the blades of the fan. A generator device is associated with the secondary fan, so that power can be generated by the rotation of the secondary fan due to the movement of the air being passed through the fan. The secondary fan may have the same number, or a lesser number, of blades as the fan, and the pitch of these blades can be such as to provide the required output.</p> |
