Whirlwind Windscreen

I must admit that looks pretty neat. I would be curious to see how it performs in more real-world conditions. My concern would be that you might need a good seal with the ground and precise distances between pot and wind screen to get the whirlwind action going. Looks are cool, but performance is even cooler. Have you performed any comparative tests using non-tornado wind screens?

You could make one of these and have some pretty crazy fire tornado action!

I have not done any boil comparisons due to lack of time during this action packed spring weather. I'm trying to configure some ridge lines into the windscreen to make it durable and user friendly. The windscreen remains rigid in a cylinder shape. I can store it around a foster's pot or store it inside. The ridglines on it really strengthen it and add protection to the foster's pot if I keep it outside the pot. The one in the video is 6" tall. I'll post a picture of it tomorrow.

According to some info that came to be in the thread where I made a Titanium windscreen, it was said that turbulent air around the pot is better than laminar flowing. Based on this info, we can only think that boil times and fuel efficiency will improve, correct? The swirling motion seems to distribute the hot air evenly around the pot. In the video I'm using a Fosters pot. I was impressed with what I saw from under the windscreen via the relection in the mirror.

I'm not much of a youtube watcher and not up to date what's going on in the stove making world so members here might be able to tell me if they've seen anything like this windscreen before. I've seen stoves that have a swirl to the flames but not a windscreen that creates the swirling motion.

Here is a photobucket video and photo of the windscreen. Notice the ridge lines that strengthen it. I’m still working on a good means of holding the screen at the appropriate diameter once placed around the pot. This type of screen should be able to benefit many different size pots. Get the flames to swirling and that should keep flames centered and give even distribution of heat around the sides of the pot.

In the beginning of the video you will see the flame area begin to get brighter. That’s a hardware cloth support beginning to glow red hot.

click on that black square to start the video. It was made in the dark so I could see whats going on under the burner/pot.

I am Darth Vader aka Stovemandan LOL

This windscreen will make all my stoves more efficient. Get that heat evenly distributed in a turbulent way and "bingo" efficiency abounds.

It's cool how it makes the flames swirl, I like watching it. I think I'll make a fire pit on the same principle. oh my, that wood look so cool LOL

"This windscreen will make all my stoves more efficient. Get that heat evenly distributed in a turbulent way and "bingo" efficiency abounds."

A vortex may not give you the turbulent flow you are lokking for. it could actually make the flow more laminer. But that said It would be interesting to see how this performs in the real world.

Steven, thanks for your insight. I'll give an update as soon as I get a chance to get out into the real world and do some testing. Home repairs and garage clean out to get ready for a yard sale is keeping me busy. I need a long vacation :-)
