    It was asked if the ARC's stoves here in the Marshall make charcoal Absolutely

    I went back and looked after we had to use the stove because the propane ran out, here in town. you answer pulpy punky material or not yes the stove does produce charcoal.

    The charcoal in the pictures is charred copra used to light the stove and the pieces of the flower shoot that even show the grain and structure of the original pieces.

    The flower shoot cover Spathe or Utak is an often used fuel anyway. Ripped by hand into small strips it works particularly well in the ARC rocket stoves. Copra, dried coconut meat, is the major cash crop and source of income for most. Its use would be limited to only a few chips as a starter material.

    I find a spritz of kerosene from a old 409 bottle or even a squirt of WD-40 does fine as a starter too. Various pieces of fronds and leaflets are really bio trash stuff and if they can be use effectively a really handy application.

    As for char structure, after it goes through my blender I am not at all sure there is much left.
    Remember I have been using Charcoal slurppees for a while. Charcoal, fish scraps if there are and a touch of 20/20/20 and a pinch of sugar.

    So better cooking and may your terra preta plot grow too.

    Firing Things UpFiring Things Up

    See slide show attached. I did this in conjunction with a Woman's Club, "Kare in Okrane." Essentially, "Women of the Break of Dawn," a reference to women getting up a the break of day to prepare for the family's day. We did have hundreds of observers and a strongly expressed interest. In this case the rocket stove had the clear edge. Burning fuel is what people understand. Women have been doing it at their grandmother's knee since childhood. The Solar oven probably came in second. Here it was much like a microwave. I had to constantly open it up and invite people to touch the pot. Ouch, that it hot, hey it does work. What can you cook in it? Sadly the TLUD was more of curiosity. . The kerosene/propane like flame did surprise people, and I repeatly brought up charcoal and terrapreta as a benefit over time. However, the small size and short burn worked against it. I simply switch between two to resolve this. Best Regards to all Michael Trevor mtrevor@ntamar.net

    Cooking on Rocket Stove While Still Starting Shell Fire
    Cooking on Rocket Stove While Still Starting Shell Fire

    Hello from the Marshall Islands, thing are progressing just slowly

    I thought you might like these attached pictures. Dean Still and his crew John, Todd and Sandra along with Dr Richard Zellar on their (Aprovecho) Board really went the extra mile to help me get the stoves here to test. It took over half a year to accomplish. I complement them for the extra effort.

    Initial reaction has been very positive, even right thru the roof. The best appellation was "fabulous", and others say "really good" or its almost like a kerosene stove. This thing really has potential to help people. Even the Ministry of Health has taken an interest for a public health view.

    The stove being used next to a "normal" open fire from shell is really illustrative. The entire pot of eggs and potatoes for a picnic salad cooked on pieces of 2 or 3 flower spathes while the other fire was still being built.

    The nearly smokeless fire is obvious. The steaming pot shows well right next to the harsh acrid shell smoke. Pollution.Junction !!!.

    As for the fuel the difference in labor should be noted, Susan simply walked across the yard
    picking up three "utok" from coconut spathes on the ground and lit them. Juli the young man however had to pick up and haul in a partial bad of nuts. Then they were husked, cracked and the meat cut out. Finally he spend the entire time Susan was cooking just getting his fire going,

    Please note Susan is not even using the stove correctly as the pot was just big enough the the skirt fell down the outside of the stove. I believe the skirt is not going to be popular even though I carefully explained its importance and use to hold heat against the pot.

    Fuel shortage is not an issue here as in some places. Right now I am working our a combination of chopped frond pieces for an XL woodgas stove and then running the midrib sections through the ARC rocket stove. The looks to be a nice usage of what is usually trash that is burned.

    Sincerely yours
