Aren there many more parts to maintain than a comparable power conventional wind turbine?
No! Parts count is comparable or less. More important is that unique parts are dramatically less when compared to a conventional big bladed windmill. That is because a WARP is comprised of many relatively simple identical parts. Reliability is a function of the number of unique parts and their complexity rather than the actual number of parts. Note, use of a thousand paper clips is more reliable than a more complex stapler used a thousand times. Absent with WARP are problematic, complex and costly gearboxes, hydraulics, large yaw bearings, large castings and forgings, and rotor pitch change mechanisms and associated computer controls. This also avoids attendant costly tooling and large transport rigs, and the need for large rigging equipment.
