 Techstuf,
looked further into the v-lim generator, almost sounds like the same idea as yours.

http://rogueriverwind.com/VLIM_Hybrid/VLIM_Hybrid_Specs.html
some info from the site
Compact ducted fan design coupled with a proprietary vortex generator aft of the fan induces a low pressure zone that extracts more power per swept surface area from the prop, just like a jet engine, than conventional wind turbines. More here
Smaller size and turbulent wind handling make the V-LIM suitable for rooftop mounting reducing the environmental footprint typical with tower mounted systems.

Thanks for the find, Helicoil, I've never seen that one before!  My design is substantially different, and with fewer components.  (Although my blade geometry is somewhat diabolical to produce with material of sufficient strength)  My design relies upon steady, comparatively high wind speeds, essentially highway speeds.  At over 45 mph, air's mass can really be put to work!

My design is basically a rip off of these guys:

I'll try and post more when I get my stationary and rotary vortex generators tuned to the output prop.  When I'm done it'll look pretty out there.  Something like the Jetsons meets Back to the future.

 Had a good laugh, looks like they spent a good weekend setting it up. (popular with the ladies),
reminds me of a funny vid i had seen of a pedal powered propellar bicycle being ridden down the city streets, looked safe for the pedestrians.
 there no way this could ever be street legal, probably any car with an exposed fan would be illegal,
 thought about a similar idea as well, using a huge scoop so fan is not exposed, always thought the drag created would be greater than the power it could produce.

More jetson than this?

Sweet!!

If  thats how we can use "Apparent wind"
So be it!

Looking forward to seeing your "Gizmo"!!

Thanks

Hi,

Intresting stuff.

I have played with the idear also. From Schauberger with his vortex theories, i
came up with this concept of a  "vortex" harnesser to be harnest in air or water..

Every ring can turn free on its own, you harvest the spinning on the outside of the ring. The inside open.

PS.  It works both ways.

High pressure low vollume > Into the small opening   

Low pressure High Vollume > Into the large opening

Cherryman, you rock. I was working on ideas with cones encapsuplating a set of incresingly smaller relatively conventional props, but you use the encapsulation AS the prop, letting nothing slip past. That's totally awesome, and every wind turbine should have this. Make more use of the space you got!

How about this amendment:
Your device is mounted a few meters off the ground, where you get good clear winds. A pipe goes out the back of it, to just above the ground. The air is slower there, thus should offer more thrust. Furthermore, ground effect makes it more resistant to expansion. Or would that an undesired effect? Perhaps it depends on the application. For DDWFTTW propulsion, my idea might be an upgrade, but if you just have a unit on your roof to supply the household's power, it's waste of energy. A complicated wind powered hair dryer.

HHMMmmm

I like the idea of a smaller prop doing more work [Techstuff] ?

That would be very nice!![extra nice!!]

?

Chet

PS
Cherryman  very cool!!

A venturi concept? wouldn't you need another "mechanism" to convert
harvested force to mechanical ?

I suppose energy could be harvested from the outside of the rings, incorperated with the external bearing assembly it would need. An O-shaped electric motor,/generator, why not?

Here is a single one, with the same basic rotor design.  Only not in a tube/cone shape.

They also draw the energy from the outer circle, some vids also.

To be honest, technically, there is a trade off.  But one that is not hard to bear....the prop's displacement in the axial direction is considerably higher than that of conventional props. 

There's more than one way to siphon energy from the 'active vacuum'....and as an 'elastic fluid' air can certainly fill the bill.  Remember, we're not talking about something designed to increase wind power efficiency on a general level.  This potential innovation is designed to be implemented at constant relative wind speeds reaching in excess of 7 times the average wind speed in North America.

I will probably post the pics, vids, and data on a site of my own after a few test runs are completed.

With this device, I'm not making any claims of OU whatsoever....but thus far, the concept appears very promising as a way to markedly improve efficiency.  I am currently working out the methodology to produce the rotor/prop assemblies accurately at full size while retaining the needed strength/durability.

The test bed should really turn a few heads when completed.  Who am I kidding?  It should turn every head.  One could power an average home with the power generated from the averaged daily head turning alone!

lol.


We'll see....

Looking forward to that, especially if it does what that forever car seems to be doing [making its own wind to run "forever"??]

I here carrots are the new high strength material [better than carbon fiber]
Quite serious.

Thanks for the 'carrot' tip, Ramset.

Wow.  80% carrot propellers, perhaps? 


What next.....Turnip turbines?


Amazing.

The sound isn't working on my computer where I'm staying ,
whats with that forever car??
what claims are they making?
Clo and others have been suggesting this is possible[making power while underway]

does this work??[forever car]
