[Stoves] Report on second day at Ethos

[Ronal W. Larson]

List


   Ethos’s second day was handled in a different way this year - all plenary style  mostly group discussion.  (All meal breaks at 2 hours to encourage discussion)

Two plenaries were at one hour:
       A.   earthen (very low cost) stoves -  led by Jon and Flip Anderson, independent ceramic stove specialists
       B    How stoves are used -  Elisa Derby of Winrock  (hours per day for each type of use and similar)  - How to quantify.

One at 1.5 hours in afternoon:
       C    Advantages an disadvantages of centralized vs decentralized production.  A general discussion - no conclusions


   Two hours 3:00-5:00 in watching stove demos. Good weather this year.  
    A.  Rocket type
        Pancakes at the Jon/Flip Anderson insulated brick stove with large griddle.   (had by far the hardest set-up)
        Cooked rice on nicely done stove with both a well designed (100%) skirt arrangement and a “hay box”  (8-9cm thick?)  retained heat cooker”.   Company: Save80
        Paul Andreatta with experimental design change to allow longer times (10-12 minutes) between fuel handling.
        Biolite
             Several others earlier on display (StoveTec, InStove,  Burn - but not cooking)

   B.  TLUD
   	Another 6-8 lit and in operation. Paul Anderson (2 or 3 ?) 
        Art Donnelly showing latest/new design - concept starts with $3 paint bucket.
   	First timer Kirk Harris had three going with different designs, showing novel way to get more than 3:1 TDR  (turn down ratio).  Also with and without insulation. 
   	Peko Pe
   	Alexis Belonio had stove to talk about but no rice husk available to demonstrate.  
             Apologies for any I’ve missed.
		(several others on earlier display;  don’t have all names.  Christa Roth had one from Paul Olivier)

Questions?    (i will try to give some overall impressions and new ideas later today)
