"Attached is a recently published article analyzing the testing (SWBT,
CCT, KPT) by SNV of rock beds and grates in open-fire cookstoves.  (No
paywall.)  Here is the online version.  The article was written by Rob
Bailis (Stockholm Environment Institute) and an SNV team led by
Bastiaan Teune.

Free rocks on the ground below an open-fire cookstove improve
efficiency by a third.  Rocks on a metal grate (< USD 0.50) improve
efficiency by almost half.  Emission reductions are even greater.

Please consider these findings when reviewing “The State of Access to
Modern Energy Cooking Services", just released by the World Bank.
This report states that $150 billion per year is needed to achieve
universal access to modern energy cooking services by 2030.  For a
minuscule sliver of that cost, rocks beds and rock beds with grates
can get us much closer to this goal.

These modifications do not make open-fire cookstoves clean.  But they
do substantially decrease:

Time spent by women collecting wood.
Deforestation
Ambient air pollution
Climate damage


Thank you,
