Applications & Cost Effectiveness

A 50 meter rotor windturbine costs approximately 2 million dollars. Construction costs include tower construction (20%) and rotor cost (20%). The cost of turbine components, foundation and maintenance does not rise in proportion to size.

Although cost information is difficult to obtain for proprietary reasons, I estimate that a multiple rotor design, with smaller, lighter and less expensive rotors, would exceed the performance of a conventional wind turbine, at a competitive cost.

This research could impact on the construction of wind turbines. Increased torque may permit increased turbine size and produce more electricity than that of a single rotor wind turbine. The use of multiple rotors to increase torque could result in lower construction costs because rotor blades would be smaller, fewer support towers would be required and the overall efficiency of wind turbines would increase.

My research could lower the cost of producing wind energy and have the added environmental appeal of requiring fewer wind towers. Less land would be utilized, less habitat destroyed and this could lessen some of the opposition to the construction of wind farms.

Wind energy is the fastest growing source of energy worldwide. I believe that it will become more popular in North America due to the Kyoto Protocol and concerns about greenhouse gas emissions.

Phase 2

"Torque it Up!" was a successful project that proved my hypotheses regarding multiple rotors to be correct. I plan to continue my research.
