Dear Corey and all
I will rather call it straw than grass. The combustion system with straw as
fuel was used as household energy in a refugee camp in North of Uganda in 1995.
The Latin name I was told was Hyperrernia Rufa and it was the straw used for
roofing. The bundles cut and transported by women was about 25 kg. The soft
part of the straw was cleaned of and the remaining straw was cut in the right
length 8” and tight up with a sisal-string into bundles of about ½ a kg.
I was working with handy-caped people that time and a lame man with
strong arms was cutting the straw with a machete and a blind man was putting
the cut straw into a form of bricks, which made it possible to produce the
right size, tied up the sisal, that was all.
The sisal string was taken off while the bundle was put into the Peko Pe and
easy ignited with some soft straw on top. Burning with clear flame with high
temperature for about 25 minutes for fast boiling and then due to the fact the
glowing straw did not collapse and the water continue boiling for another 25
minutes from the glowing. Different types of reeds and papyrus were used with
same result. The system was used for cooking, frying, baking bread and griddle.
We used papyrus with very high flame temperature for melting scrap
aluminium to mould pots and small blacksmithing from the glowing.
The charcoal business did not like the system of competition
reasons.
