I've seen something similar using cylinders or cones in a old Popular Mechanics magazine from the 70's. The blades(?) are spun up to speed with a little motor, and the surface tension on the rotating tube creates lift. There are videos on YouTube

This Spiral Mangus thing adds spirals to the cylinder, which look like they provide the spin to the cylinders instead of using a motor.


Lots of moving parts.

I saw this editorial, which in part reads:


Wisconsin has set lofty goals for use of renewable forms of energy in the coming years as a way to reduce reliance on fossil fuels for generating electricity.

The Legislature took a major step toward reaching those goals when both the Senate and Assembly passed a bill requiring the Public Service Commission to develop uniform rules regulating where wind farms can be located, including setbacks from homes and businesses, noise limits and height restrictions.


At present, the Public Service Commission has authority over wind farms that generate more than 100 megawatts or more and local government does the permitting for wind farms under 100 megawatts. But the local standards differ widely from one unit of government to another.


Some have even used these siting powers to effectively ban wind farms altogether.

Although some local units of government, notably several towns in neighboring Fond du Lac County, have developed reasonable rules on siting of wind farms, too many others have done the opposite. As a result, plans for wind farms capable of generating more than 600 megawatts of energy have been stalled.


Just this week, officials at Lakeshore Technical College, which has its own wind turbine and teaches turbine maintenance, said the school is working with a Japanese company on the next generation of wind turbines that the firm says could be built locally. We applaud LTC for being a leader in developing programs to support this is just the kind of new manufacturing that will help Wisconsin's economy rebound.

 Just another latest and greatest idea brought back from the 70's and possibly earlier. I'll stick with 3 moving parts thank you. Dave B.

Dave;


A lot of that going around lately. Some even manage to patent them, too.


Go figure.


Well said!

Thanks Tom,


  I sure hope we don't see Ace Hardware selling the (spiraling blades) as the absolute best HAWT right next to the absolute best VAWT (the Honeywell inside out alternator). Oh boy.  Dave B.

That's pretty cool!

I don't see it as being overly perfect, but it is neat.

Looks like a John Deer Unit with that yellow and green paint.

Come to think of it, it looks like 3 grain augers on a hub.

There is no debate on the best blade profile with that thing at least.

I'm not saying that this is something someone can DIY in their garage.


There has been a large wind turbine farm set up not far from here, and I know that there have been many complaints from near by home owners that have claimed that they are bothered by the noise.  I was able to drive up real close to one in operation and did not hear anything I thought was objectionable,  How ever I was under it and not adjacent to it.


They claim that this turbine is very quiet.    If this is true and would improve acceptance with the local home owners (and those who worry about bird strikes) why not keep an open mind about it?


I live in a very UN-friendly Windgen location So putting up one in my back yard isn't going to happen,  but I do support Wind power and would like it to advance and improve it's acceptance.


Anyways...  this one still looks weird to me!   and here is a bit more info on it..

- Spiral magnus is less intimidating because rotational speed is about a quarter of common propeller types.


 - And their gear box is now 4 times as expensive.

I looked extensively at their site. I could take them a lot more seriously if they didn't delve into H2O Pseudoscience. H2O Quackery at its finest.  :(

Or if they had run it through a spell checker instead of worrying more about making it look all pretty with flash... "No Break Required at extreme wind conditions" and it's perfect for "Villeges".


If that was my first introduction to it, coupled with the H20 crap, I would have dismissed it entirely and gone on about my day... figuring that the spirals would then be powered by perpetual motion, and the entire site validity lost.

The size of the project matters not.
How much magic smoke it contains does !
