Our stove held up pretty well during the test. The chimney worked, and we did see smoke coming out of it. The drawers and different parts of the stove functioned as we intended, and the water was heated a little bit, although it did not reach a boil. The charcoal cooled down quickly after the fire started were all burned up, and we attributed this to an inadequate amount of air flow to the fuel drawer. Overall, we were happy with our results, but we wished that the charcoal had heated the water more effectively. Given that, we would change at least two aspects of the design. We would decrease the space between the charcoal and heating surface, as we saw how groups with a shorter distance between these parts were able to heat their water to higher temperatures. We would also increase the flow of air to the fuel drawer in order for there to be more oxygen and combustion.
The water reached the highest temperature, 43.5 degrees Celsius, after 5 minutes of heating.
I agree with your thoughts about decreasing the space between the charcoal and the top of the stove, as well as lifting the stove up to get more airflow to the charcoal. I think our plan for a two-temperature heating process was ambitious but overall ineffective.
