    Nordica MacCarty says:

    More thorough performance and safety testing are recommended, even a simple WBT without emissions and safety evaluation should be conducted to report important metrics such as thermal efficiency and safety score. The stove design looks unstable and likely has a high surface temperature which should be noted in decision-making and would become apparent through evaluation. Also, please be more specific about the fuel supply and preparation.

    Thank you very much for the feedback. I have included WBT information performed by Approvecho as well as a link in design specifications that throughly discusses the variety of dry biomass appropriate for use in micro gasifier stoves. Regarding safety of the stove and stability, I have not come across any information suggesting this. I have attached a link to a recent 2016 case study in which 11,000 stoves were distributed in Deganga, India (in the snapshot section). This intervention has also seen a successful charcoal buyback program and I have included a sentence about economic opportunity that the stove can provide.
