The first time I tried the rocket stove, it died after 20 minutes. This time I stacked it differently and kept the feed tube half full of sticks. The upshot of this stove is that the air can only come in from one side. Turn the side tube into the wind to build (or re-stoke) the fire or away to keep strong winds from blowing it out.
Today it was 30 degrees Fahrenheit and fairly windy. I set up in our screened-in converted gazebo. Then, I packed my Toaks 1600 ml titanium cook pot with snow and put it on the stove.
After 10 minutes, the snow had melted, and after 18 minutes the water was almost at a rolling boil. The 1600 ml of snow became 20 oz of water ready for a packet of instant coffee.
The main part of the stove was made from a can of pineapple juice, the side tube came from a can of chili beans.
The bonus of these stoves is how little wood it takes to cook a meal.
Next time, I’m going to make a wood-gasifier (ranger) stove.
To prepare the sticks and limbs which we’ve collected from around the yard, I used a CRKT M21-SF14 folding knife, Fiskars X7 hatchet, and Mechanix gloves. I was able to feather the wood and make thin shavings using the hatchet. I also used a ferro rod, fatwood, and vaseline-lint ball to start the fire.
