Organization: Appa Technology Initiatives
Grant Amount: $74,915
Grant Term: 12 months
Project Description:
The purpose of this project is to research the feasibility of developing a more efficient wind turbine by employing a design that incorporates dual counter rotating rotor blades. Prototype will be fabricated and tested.
Proposed Outcomes:
· Prototype wind turbine with counter rotating rotors
· Improved wind turbine alternator design
· Feasibility analysis based on performance of prototype
Anticipated Benefits:
· Increase wind turbine efficiency by 20-30%
· Achieve power generation cost of 3.5 cents/kWh
· Reduce capital cost of installation due to reduced torque load on support structure
· Retrofit existing utility scale wind turbines with downwind counter rotating turbines for enhancement of power generation.
