wind spiral idea, has anyone done this?

I heard a suggestion to face a rocket stove toward the prevailing wind, but where I am the wind seems to prevail in different directions pretty frequently.  

I thought maybe wind could be persuaded to head toward the rocket stove with a spiral of some sort to capture it, a wind tunnel, or even a solar air conditioner.  

Has this been done, and what is it called?
If not, does anyone want to try it?  maybe someone with extra throw-away billboards??

Or just a wind funnel that can be aimed a little bit?

a funnel that can be turned in any direction with a 5" plastic piping?

A magic version of that that doesn't require plastic but is still aim-able?

maybe it'd be simpler to move the stove each day, but I think the wind tunnel aspect of this at least is a worthwhile idea.  It really does get a lot of leverage.  A couple of old doors or billboards or garbage bags stretched tight somehow or >>>>

I have a vague recollection of some ships having an "air funnel" on deck intended to help push fresh air down into the living quarters and kitchens. I also recall that they could be moved to various directions. We've got something similar, but in the reverse on the output of our chipper/shredder so that we can change where the pile is forming without moving the whole tractor. You would want more of a "funnel" shape than just a "shoot" shape, but like our C/S it should have some sort of fastening method so that it stays pointing the direction you want it to.

maybe you could make an exhaust pipe that is kinda long horizontally at the top which can be spun and then locked into place. Where I live the wind always moves east unless there's crazy weather so idk if you really need it.

Hi Joshua,   I'm curious to know what your idea intends to accomplish with the rocket stove? To increase draft? A rocket is named that because the draw is already quite strong as it whooshes down the the burn chamber creating a really hot and clean burn. To increase the draft would mean it would turn into a blast furnace and may actually make the burn not quite as clean since it doesn't have the dwell time to completely combust all the fuel in such an oxygen rich fuel mix.

Interesting point.  Well, this is a super-low-tech, 4-cinder-block version, or maybe 4 and a half, what i had lying around doesn't resemble how they make it look on youtube.  So adding a little extra draft seems like a good idea, and the person in the video aimed it so the prevailing wind would blow into it.  

I have a better version on the way that I just ordered, but I thought this might be a good add-on for anyone using the 4-cinder-block version.  And anyway I still have to get the firebricks and all, so it may be a while before I can use the clean-burning version.
