The Pop-Up Two Buck Stove
Lanny Henson, November 27, 2007
This is the first prototype of the Pop Up Two Buck Stove, a compact, clean burning, wood fired, natural draft design. I have use easy to learn methods and inexpensive common materials, so the design will be one that an average person could learn to build.
150 grams of wood boiled a liter of water in 18 min. and retain 21 grams of charcoal.
150 grams of bamboo cooked 1.1 kilos (cooked weight) of rice.
001- Is a compact, natural draft
002- Clean burning
006- Fuel-efficient stove
005- 150 grams
007- boils 1 liter
009- and makes 21 grams of charcoal
010- The Side Supply Burner is top lit.
011- In with the pot at 3 min
012- At 5 min
013- At 7 min no visible smoke
014- At 11 min all clear
015- At 15 min a whiff of smoke
016- At 17 min clear exhaust
018- At 18 min from striking the lighter, a rolling boil
019- There were 21 grams of charcoal left.
020- The Pop-Up is made entirely from 4 recycled cans
021- Using simple tools
022- And methods
023- The Pop-Up Stove would make a good portable rice cooker.
025- 150 grams of bamboo
024- Cooks 1.1 kilos of rice =350 grams dry weight = 7.7 servings
This is the first prototype of the Pop-Up Stove and I am pleased with its performance. I am especially pleased that the Side Supply Burner works with such a short draft height. It does take more skills to operate being so short. You have to know your wood and tune the burner to it. This would be a bigger problem if large quantities of fuel were being consumed but at 150 grams per use, maintaining consistent fuel would not be as big a problem.
I am going to make some improvements to #2 so that it will pack better and build a separate burner for bamboo. The burner that I am using is tuned for pallet oak and dead fall oak limbs. It burns bamboo a little too fast which creates fire in the gap and more smoke.
