Rocket Stove!

March 23, 2015

Limalimo Lodge recently hosted a few energetic supporters who wanted to get their hands dirty on site. So we put them to work building a rocket stove. For those of you who don't know what a rocket stove is, fear not: we have pictures. And there are a lot of websites devoted to these amazingly simple and efficient "mass heaters". We recommend starting with the folks over at Rick Soil. As they write, "This could be the cleanest and most sustainable way to heat a conventional home." We're all about sustainability at Limalimo so we thought we'd give it a try. The photos below represent a test product; the final design is built into the fire pit up top to keep things nice and toasty on cool Simien evenings.

Step 1: mix up some clay and water to create a bond that goes around the bricks

Step 2: we laid out the bricks to make sure we had enough (we bought 100; that was enough for our purposes)

Step 3: we used a tiny bit of cement to hold the bricks together. We also filled a few of the bricks, so air would not pass between the vertically laid bricks (we had access to exceptionally good equipment):

Some of us focused on mixing, while others majored on "supervising":

Step 4: we organised the bricks into position, and packed the clay / water mix around them to keep them in place and create the heat-trap that we were looking for:

Step 5: After getting enough of the bricks and clay mixture into position, we added the "combustion chamber" (ie. the big ugly blue drum), and the smoke stack (ie. the old metal bit sticking out of the back end). We packed in more of the clay mix and let it dry for a little while. Then we lit it... And it worked!undefined undefined

Step 6: we celebrated as the sun set over Limalimo!
