Background Recent work has examined behavioral reactivity associated with personal awareness of electronic sensors monitoring the use of environmental health products, including cookstoves. These studies suggest that sensors could be used as behavior change tools. Objective We present a human-centered design approach toward the development of a household air quality feedback technology intended to improve consistent and exclusive use of liquid petroleum gas (LPG) stoves provided as part of a health efficacy study. Methods We found through a consultation process that households may be behaviorally triggered by reminders of the health and environmental impacts of cooking practices and may respond to both auditory and visual feedback. Based on these insights, we designed and validated a system linking air particulate monitoring with persistent visual feedback and a dynamic audio alarm. Results Data collected over 14 days in participants households show that the system is able to detect sudden rises in household indoor air pollution and to communicate that information to household members. Significance This device could be used as a tool to raise awareness of air pollution associated in order to stimulate adoption of cleaner cooking technologies.

“…intervention study design (Mukhopadhyay et al 2012). User-centered design has also led to diversification of stove installation options in the field (Thacker et al 2017) and influenced design and implementation of policies to promote cookstoves (Lambe and Atteridge 2012). However, early integration of user needs and preferences to constrain core technical design, as we did here, has not been presented at a similar level of detail for past stove development.…”

“…The majority of household stove design efforts have emphasized technological advances and laboratory performance (Kumar et al 2013). Some stove design efforts have addressed other design criteria, including fuel cost and access (Febriansyah et al 2014, Ahiduzzaman andIslam 2013), multi-functional stoves (Raman et al 2014), and user experiences, preferences, and input (Thacker et al 2017). However, integration of these design criteria throughout the stove design and development process, while maintaining high-level performance in the field, has been lacking.…”

Unclean combustion of solid fuel for cooking and other household energy needs leads to severe household air pollution and adverse health impacts in adults and children. Replacing traditional solid fuel stoves with high efficiency, low-polluting semi-gasifier stoves can potentially contribute to addressing this global problem. The success of semi-gasifier cookstove implementation initiatives depends not only on the technical performance and safety of the stove, but also the compatibility of the stove design with local cooking practices, the needs and preferences of stove users, and community economic structures. Many past stove design initiatives have failed to address one or more of these dimensions during the design process, resulting in failure of stoves to achieve long-term, exclusive use and market penetration. This study presents a user-centered, iterative engineering design approach to developing a semi-gasifier biomass cookstove for rural Chinese homes. Our approach places equal emphasis on stove performance and meeting the preferences of individuals most likely to adopt the clean stove technology. Five stove prototypes were iteratively developed following energy market and policy evaluation, laboratory and field evaluations of stove performance and user experience, and direct interactions with stove users. The most current stove prototype achieved high performance in the field on thermal efficiency (ISO Tier 3) and pollutant emissions (ISO Tier 4), and was received favorably by rural households in the Sichuan province of Southwest China. Among household cooks receiving the final prototype of the intervention stove, 88% reported lighting and using it at least once. At five months post-intervention, the semi-gasifier stoves were used at least once on an average of 68% [95% CI: 43, 93] of days. Our proposed design strategy can be applied to other stove development initiatives in China and other countries.

“…Reports have also shown that skirts improve the thermal efficiencies of wood stoves when used on them. Thacker et al (2017) for instance stated that the traditional channel cook stove have a very low heat transfer efficiency; pot skirts were reported to be one of the most effective ways to improve this deficit. They also stressed the importance of increased heat transfer efficiency to be decrease in cooking time and smoke reduction.…”

The importance of heat energy source from wood to humanity cannot be over emphasised since many depend on it for their heating needs. In this work, a wood stove was designed, constructed and tested without a skirt and with a detachable skirt of height 120 mm (same height as the pot used for the experiment) to ascertain the influence of the skirt on the stove in terms of thermal performance in a water boiling test. Thermal efficiency and specific fuel consumption were evaluated. It was found that the stove tested without a skirt gave an average thermal efficiency of 31.33% and an average specific fuel consumption of 0.14 kg/l. When tested with a skirt, however, the stove gave an average thermal efficiency of 38.65% and an average specific fuel consumption of 0.09 kg/l. This signifies an improvement in thermal performance by the use of skirt on the stove designed. Keywords: Humanity, Globally, Detachable-skirt, Thermal performance, Wood stove.
