In their their sixth blog post for Scientific American, they speak evocatively of their efforts in collecting emission date from three-stone stoves among the villagers of Kalinzi, thus:
"Our first order of business involved collecting quantifiable emissions data from charcoal and three-stone stoves—the current standards among most Kalinzi villagers. The two main problematic components from stove emissions are carbon monoxide, which has been linked to maternity problems, and fine particulates, which contribute to Acute Respiratory Infection (ARI). We decided that our own kitchen was a good place to start and proceeded to take data as our cook, Tuma, prepared lunch and dinner. After a full day of monitoring the efficiency and particulate emissions generated from our stove, we went to the local cinema to watch a soccer match. The tiny building was set up like a church with a center aisle and about 15 rows of simple wooden benches containing 100 or so Tanzanians, with soccer as the object of worship.
The next morning, we woke up before sunrise to the crowing of roosters and began our first full day in the village. Our objective was to finish designing a top lit updraft (TLUD) gasification stove that could burn coffee husks. The TLUD concept was pioneered by Paul Anderson, an expert on Improved Cook Stoves (ICS) for developing societies, whom some previous HELP students were lucky to meet in the spring during an assessment trip..."
