First Extended Life Prototypes Hit the Field!
The Extended Life Stove project, a two-year project to extend the usable life of BURN Manufacturing’s (BMC) current production stove, has recently seen major progress.
Our last update described the prototype stoves containing various types of ceramics that were about to enter the durability program. While most of the stoves were entered promptly, one stove was kept aside for market research, as connecting with potential users of this product is crucial to its success. To this end, the BURN Manufacturing Market Research team performed a street survey of one of the stoves. In this study, the research team took the stove around town and gathered opinions from many people in the area. BMC team members asked survey participants to compare the current production stove with a prototype ceramic combustion chamber (pictured). The results of the study were encouraging; in fact, most people thought that the ceramic combustion chamber was a considerable improvement on the stove and expressed a willingness to pay slightly more for a stove with a longer lifespan than the current model.
As these positive results from the field trickled in, the sample ceramic combustion chambers were delivered from our suppliers. These combustion chambers are full cylinders (instead of the octagons we prototyped) which hopefully are much more similar to what we may end up using in the final product. We ordered two different types of material to determine the optimal combination of properties and geometry.
Both materials are suited to high temperature environments, but extended time in the durability program will show if one outperforms the other over time. We are currently sending samples to the factory in Kenya so that they may be entered into the durability program in the next few weeks. As the stoves begin to run, we eagerly await results to further understand how we can improve the lifetime of this product.
