From watching your videos it is clear this is functioning as a hybrid between TLUD's and flame caps. Do you make any attempt to regulate the air from below? When we go to Aprovecho I can easily make a band and we can do emissions testing on this new arrangement. I still plan to compare emissions of dried maize stocks versus maize stocks at ambient relative humidity. I think there will be a difference. I'm also planning to do this in a metal band versus the "conservation burn" style you originally worked with.

We've long been trying to find a way to use maize stalks as a cooking fuel<br>
in Africa. They are challenging because they burn fast and smoky. We may<br>
have found a way.<br>
<br>
Make a bundle of stalks in a metal band and stand up the bundle so the<br>
stalks are upright. Then light the top. The band has a diameter of 20<br>
cm. The stalks burn remarkably clean for about 13 minutes, no tending.<br>
Then a new bundle can be swapped in to continue the cooking. Below are<br>
some videos.<br>
<br>
My colleague in Uganda thinks that farmers with two growing seasons can<br>
cook year round with maize stalks and never need to collect firewood again<br>
... we'll see.<br>
<br>
As a bonus, this makes biochar.<br>

@Kevin<br>
<br>
Imagine you rise the sleeve higher up and leave some space between it and the bundle.<br>
It should have a "secondary air effect", I guess, and burn even cleaner.<br>
