There is no problem attempting to sell a stove that needs novel fuel, or a processing method. But if you are told from the start not to bother, they will refuse to use it, it has to be treated as valuable information. </div>

When an industrial designer assess what to create, the customer sets the parameters. Apple famously held that people don't know what they want yet, they have to be told. Well stovers, a lot of cooks know what they want and what they don't. </div>

<div class="">Dear Crispin,
<div class=""><br class="">
</div>
<div class="">I agree with the stove designer/selector criteria for guiding the process making a stove. But before taking it into the field I suggest it be tested using the biomass available and biomass optimized for that stove. That to be included in the instructions.
I realize people are going to use the stove as they wish. But knowing how to prepare the fuel for optimum performance is a start. </div>
<div class=""><br class="">
</div>
<div class="">Preparing the fuel for stoves takes time and energy and may seem silly and likely not going to be done. BUT if the fuel is the variable that now needs control we will never get cleaner stoves until this is done - no matter what stove they use.
I think a process that sizes and dries, splits, chips - whatever the available fuel before use is the best next step to cleaner stoves. </div>
