Maximizing Wind Turbine Efficiency: Is Redirecting Wind Worth the Cost?

Click For Summary

Discussion Overview

The discussion revolves around the potential benefits and drawbacks of using structures to redirect wind towards wind turbines to enhance their efficiency, as opposed to simply installing more turbines. Participants explore various design ideas, practical considerations, and the economic implications of such approaches.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • Some participants suggest that placing inexpensive objects in front of turbines to redirect wind could be beneficial, while others question the practicality and cost-effectiveness of such designs.
  • One participant notes that wind turbine designers likely have explored all efficiency options, implying that if a method is not widely used, it may not be effective or economically viable.
  • A participant proposes a funnel design to increase air speed towards the turbine, but raises concerns about the size and resource requirements for such a structure.
  • There are discussions about the need for any redirection mechanism to adjust with changing wind directions, which complicates the design.
  • Some participants express skepticism about whether a funnel system would outperform a larger turbine, highlighting the challenges of managing airflow and back pressure.
  • Concerns are raised about the lack of empirical evidence or research supporting the effectiveness of redirecting wind towards turbines, with requests for links to studies or data.
  • One participant emphasizes the complexity of aerodynamics and suggests that proven designs should be utilized rather than experimental approaches.
  • Another participant shares their personal experience in building a wind turbine and expresses a desire for input on their design, indicating a hands-on approach to the topic.

Areas of Agreement / Disagreement

Participants exhibit a mix of agreement and disagreement. While some acknowledge the potential for redirection methods, others challenge their feasibility and effectiveness. The discussion remains unresolved, with multiple competing views on the best approach to maximizing wind turbine efficiency.

Contextual Notes

Limitations include the lack of consensus on the effectiveness of redirection methods, the dependence on specific design assumptions, and the absence of empirical research to support various claims made in the discussion.

Most countries that have a subsidy base it on the amount of electricity generated so it's in the interests of the wind farm developer to generate as much as possible. So it's not subsidies that stop developers installing larger turbines. Most new onshore turbines in the UK are 120-136m tall. Larger turbines are available (190m) but they aren't normally used onshore due to the impact on the landscape. They are however used offshore. If you use big turbines you need fewer of them and fewer foundations, cables etc so the capital cost per MW is lower. There are lots of reasons why developers would like to install bigger turbines.

It's not too late to be asking the OP what kW rating alternator is being planned. There are two threads progressing, unaware of each other and in parallel, I think. Comments about one do not apply to the other.
