与危地马拉农村典型的露天烹饪炉火或传统的半封闭炉灶相比，开发出了一种催化火箭炉灶，以减少排放并提高效率。传统炉灶通常会排放足够多的颗粒物和一氧化碳，导致呼吸道疾病和其他健康问题。根据焦点小组的结果，炉子是根据危地马拉厨师的需求量身定做的。现场试验参与者接受了炉灶培训，以确保炉灶正确运行。有些令人惊讶的是，现场试验表明，危地马拉农村地区的用户接受度很高，那里的用户93%的时间都是用催化炉做饭，尽管必须改变一些烹饪做法。在现场试验中，与传统的POYO相比，该炉子在现实世界的烹饪活动中减少了高达68%的排放，并提高了高达61%的燃油效率。实地研究的另一个定性部分确定了炉子的优点和缺点，这些优点和缺点正在作为迭代设计过程的一部分加以解决。
A catalytic rocket stove was developed to reduce emissions and improve efficiency compared to open cooking fires or traditional semienclosed cookstoves, called poyos, typical of rural Guatemala. Traditional stoves often emit particulate matter and carbon monoxide at sufficient levels to cause respiratory illnesses and other health problems. Using focus group results, the stove was tailored to the needs of Guatemalan cooks. Field trial participants were provided with stove training to ensure that stoves were operated correctly. Somewhat surprisingly, the field trial demonstrated a high level of user acceptance in rural Guatemala, where users cooked 93% of the time with the catalytic stove despite having to change some cooking practices. In the field trial, the stove reduced emissions by as much as 68% and improved fuel efficiency by as much as 61% during real-world cooking events relative to the traditional poyo. An additional qualitative portion of the field study identified strengths and weaknesses of the stove that are being addressed as part of an iterative design process.
