Invelox wind turbine claims 600% advantage in energy output

SheerWind, a wind power company from Minnesota, USA, has announced the results of tests it has carried out with its new Invelox wind power generation technology. The company says that during tests its turbine could generate six times more energy than the amount produced by traditional turbines mounted on towers. Besides, the costs of producing wind energy with Invelox are lower, delivering electricity with prices that can compete with natural gas and hydropower.

Invelox takes a novel approach to wind power generation as it doesn’t rely on high wind speeds. Instead, it captures wind at any speed, even a breeze, from a portal located above ground. The wind captured is then funneled through a duct where it will pick up speed. The resulting kinetic energy will drive the generator on the ground level. By bringing the airflow from the top of the tower, it’s possible to generate more power with smaller turbine blades, SheerWind says.

Wow thats amazing if true...

I will definitively dig deeper into this one!

However I dont know if it will become as popular as traditional wind technology because it does not have a lot of Fans.....

Imagine a building with this on all its sides and solar panels on the roof.

Air flows 'up' a chimney because 1- heat rises 2- as wind flows above the chimney hole it creates a low pressure that if designed properly will draw air out of the chimney when the wind blows. I've been in cold houses in calm days/nights and you could feel a draft of cold air sinking into the house Android APK

punny guy! ^^

but what about natural air flow - look a a chimney - air naurally flows up in a chimney because of difference in pressure or smh you know... how can it pick up speed by ravellin in opposie direcion? or am I missin somehin

It would seem to me that as the air in this system gets compressed somewhat from the cone shape of the inlet horns that the weight of the resulting air would enhance the effect. *pure speculation on my part*

That makes sense. Thanks, Chris!

Look at the original GizMag article. They very explicitly say that SheerWind have not explained what that '600 percent' (maximum of a range of 80-600 that they say averages out just over 300) is an increase of. It could be that they are comparing how much energy is generated for a given turbine diameter compared to if they just left it in the free airstream.

Even if they could reliably get 300% more power out of an airstream with a duct that brings the flow downwards, which they haven't clearly shown or explained, the duct needs to cost less than three more turbines in materials for the application to be worthwhile.

Compare this to another duct solution from Kyushu University that adds far less material for similar gains, where they clearly show their methods and data.

Definatley something thats very exciting, This sort of thing could be the new high tech chimney? obviously this would have to be refined alot more. I wonder if this could be implemented into off grid single housing setups. and obviosuly....the cost is a factor, living in a countryside rural area, we dont lack wind at all.

I have read your post about Restoring Navigation Links in the Header Menu of SharePoint, this is very informative post really like it a lot.Thanks for sharing the post. www.roof-removals.com |

Sounds pretty cool, wound be interesting to know how intermittent/sensitive it really is. But nonetheless, a simple applicatioin of Bernoulli's principle.

By bringing the airflow from the top of the tower, it’s possible to generate more power with smaller turbine blades, SheerWind says. I am glad to find this article. It is my honor. Nice information, valuable and excellent design, as share good stuff with good ideas and concepts, lots of great information and inspiration, both of which I need, thanks to offer such a helpful information here.

It is safe to say that you are considering buy research paper another auto? Here are some new auto purchasing mysteries you ought to be familiar with. In any case, when you have money accessible, it is ideally that you fork it out and fork over the required funds. Finishing so will help your plan massively.

When you have ever planned to one day get into graduate school (or all the more particularly, addition induction to the doctoral program in brain top school psychology graduate programs) at UCLA in Los Angeles, California, then you've gone to the perfect place! Right now stacked up at number 3 by U.s. News and World Reports for most fittingly general graduate program in brain science, University of California at Los Angeles has requisitions spilling in from people everywhere throughout the nation.

I obviously like it and i hope i will read another post this author. I think it might be really incredible. It's cool, that author decided to write on this theme. He might be interesting and awesome person.

This might just be the weather fooling me. Sudden wind change or something like that. It sometimes happens that I get fooled by the weather also. http://www.gamesforge.eu/
