Boiling water is the task. You have two months to do it. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>If you do the tests in triplicate that’s 30 runs. If a test consists of 3+ runs because the method requires you to take into account the left over fuel to be added to the next run – you now have 90 runs. So we should try to come up with a procedure that gives us the info we need in a single run. For –any- stove that has a secondary burner I suggest that a method that ends when the secondary flame goes out and the energy value is the E450c will work.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Fuel; What is the best info that we can use to find a similar fuel (to the planned location) for testing the ten stoves? I suggest the E450c to be the most important as that value is sure to be used in the secondary and, I’m thinking, consists of a large percent of the energy for the secondary. Then we have size, shape, bark, split, moisture etc. And we need all the additional info in the six box system that needs be added to the report.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>I do think we need more than Fuel Usage as a measure because to get that value it requires many, many runs and not very appropriate for a single task. We still need Energy Usage to normalize similar fuels (using E450c) and give us our single energy value for the task. We would do three runs and average for the final report. We can always calculate the Fuel Usage (for the actual fuel used on location) from the Energy Usage. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>And for the final step we need to collect all the char and send it in to a good lab for testing. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>There are many variables in this type of lab test.
