@Kevin

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

Subject: [Stoves] ***SPAM*** Maize stalks as cooking fuel in bands and bundles

We've long been trying to find a way to use maize stalks as a cooking fuel in Africa.  They are challenging because they burn fast and smoky.  We may have found a way.

Make a bundle of stalks in a metal band and stand up the bundle so the stalks are upright.  Then light the top.  The band has a diameter of 20 cm.  The stalks burn remarkably clean for about 13 minutes, no tending.  Then a new bundle can be swapped in to continue the cooking.  Below are some videos.

My colleague in Uganda thinks that farmers with two growing seasons can cook year round with maize stalks and never need to collect firewood again ... we'll see.

As a bonus, this makes biochar.
