The invention relates generally to the field of fluid driven turbines, such as wind turbines, wherein electrical power is generated from airflow across rotor blades. More particularly, the invention relates to such turbines wherein the blades extend from a central rotating hub or shaft member to an outer annular rotating ring or rim member. Even more particularly, the invention relates to such turbines wherein rotational energy is transferred by a cable, rope, belt or the like positioned on the outer rim of the turbine.
