We start off with a tour of the rocket stoves on the Aprovecho campus. In the outdoor kitchen there is a rocket stove for boiling water (the Oaxaca One-Pot) and a rocket stove griddle (the Justa stove). In the Boathouse there is a rocket mass heater.
The Oaxaca One-pot is essentially a rocket stove covered in cob, with a “pot skirt” – a sunken area for the pot to sit it. The pot skirt creates an increased surface area for heat conduction into the pot.
The rocket stove was developed here at Aprovecho by Larry Winiarski. One of the basic principles of the rocket stoves that increases the efficiency of fuel combustion is the insulated combustion chamber. Here are some schematics I pulled off the internet demonstrating the main components of the rocket stove design:

Then we started our project of building a new outdoor Justa (pronounced HOO-sta) stove:
