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

[Kevin McLean]

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.
