I was wondering if placing something (cheap) in front of a wind turbine to redirect more wind towards it would be worth it or should I just place more (expensive) turbines?

Is that possible? In the end, you still have to remove the air that has passed through the turbine and that requires some Power, however you achieve it. I guess you could argue the fact that the turbines in jet engines use multiple stages as a support for your basic idea but, again, there is the steering problem, which is not present in aircraft propulsion.Larry Payton said:I am also trying to use the exhaust air without creating back pressure
Larry Payton said:Thanks, but that's another question.
This entire circle of wind energy is shrouded with a lot of opinions without any real facts or reasearch.
If the wind farms have tried this I am unaware.
Can you link me to a website that would show they have tried thus or even reasearched the possibialities.
The business of Aerodynamics is extremely complicated and not at all intuitive. Designing turbine blades and aircraft wings are very similar exercises. How many enthusiastic experimenters would ever have come up with the efficient wing designs on modern airliners? It's always fun to experiment but building a series of turbine blade designs is really not easy for the home constructor (unless you have a large 3D printer?) I think that using designs that have already been proven is the way to go. Photos of existing designs would give you a good idea of optimum pitch and aspect for the blades. (I'm suggesting a bit of industrial espionage.) Use the benefits of someone else's R and D.anorlunda said:No and that's my point. Don't you think that if there was any reasonable way to do it better that they would have done it?
In today's world, we have so many smart people that it is really difficult to have a truly original idea. I need to constantly remind myself that the reason I don't see my "original" ideas implemented, is not that nobody else thought of them but more likely that someone else thought of the idea and rejected it. If he documented the reasons for rejection in an email to his boss, I'll never find the email.

I'm not sure what your 'high wind area' comment was referring to in your quote from my post. Was it my comments about wings? But the same requirement for efficiency is there with wind turbines.Larry Payton said:I am actually building one no just talking about it!
That can be a recipe for wasting an awful lot of time and money. Repeating someone else's mistakes when one could have read about it and understood why it went wrong can be a pointless exercise. Life's too short to repeat past errors - unless you just like making things that don't work.Blank_Stare said:Don't let ANYONE tell you that it can't be done,
It's still the wrong way round. It's up to the person with the idea to prove that it has legs and not up to others to try to prove it won't work. That's a general principle in Science. If something is presented on PF and elsewhere then it's judged on what can be read. If it isn't supported by theory or evidence then it is fair game for people to "nay say" it. Anything that's 'just an idea' can expect a bumpy ride unless someone reads it who happens to have some information to support it.Blank_Stare said:.

Someone said don't you think if there was a better way they would be doing it, well NO I don't because the government is involved it by giving tax breaks.sophiecentaur said:I'm not sure what your 'high wind area' comment was referring to in your quote from my post.

To be fair, I have installed one. so I am not just talking about it. But it was out of a box.
'Talking about it' is what theoreticians do a lot of. And they can be 'right' about a lot of things - and someone who builds something doesn't always get it to work in the way they hoped. A good bit of theory can prevent that problem. As you are in close contact with various designs of blade, it should he possible for you to take some useful measurements. What construction technique are you planning for the blades?
sophiecentaur said:Well, let's examine the whole sentence.

I agree that this is getting to be a side track but I have to ask why anyone would post information about a project that they are contemplating or engaged on if they don't want a critique of their ideas. Amongst some rather unspecific 'nay saying' there are some perfectly good reasons given for using a different approach. The past experience of others is always a good thing to pay attention to, surely. Even Newton acknowledged that and he had an ego as big as a house.Blank_Stare said:Your general principal of science does not necessarily apply when it comes to what does or does not motivate a particular private individual's creativity.

You really don't need to act as the OP's lawyer about this, you know.
Those comments do apply to domestic and On-Grid applications but there are many other uses (lower power) for turbines and they are far more suitable for personal experimentation. There is no government incentive for small systems, afaik, so no uninformed bias there.Larry Payton said:Someone said don't you think if there was a better way they would be doing it, well NO I don't because the government is involved it by giving tax breaks.
So the bottom line of the current wind turbines is based on government subsisted programs and tax breaks.
Larry, can you guide me to finding more information about the tax breaks that you are referring to?Larry Payton said:Someone said don't you think if there was a better way they would be doing it, well NO I don't because the government is involved it by giving tax breaks.

Redirecting wind can significantly increase the efficiency of wind turbines. By redirecting the wind towards the blades at a more optimal angle, the turbines are able to capture more energy from the wind, resulting in higher power output.
The answer to this question depends on various factors such as the location of the wind turbine, the cost of the redirecting mechanism, and the expected increase in efficiency. In some cases, the cost may outweigh the benefits, while in others it may be a worthwhile investment.
The increase in efficiency from redirecting wind can vary depending on the design of the wind turbine and the effectiveness of the redirecting mechanism. However, studies have shown that it can result in an efficiency increase of up to 20%.
One potential drawback is the initial cost of installing the redirecting mechanism. In addition, if the mechanism is not properly designed or maintained, it can cause damage to the wind turbine and decrease efficiency. There may also be additional maintenance costs associated with the mechanism.
Yes, there are other methods for increasing wind turbine efficiency, such as using more efficient blade designs, optimizing the placement of turbines, and implementing advanced control systems. These methods may also be more cost-effective than redirecting wind in some cases.
