Efficient cook stoves from Aprovecho win them the 2009 Ashden Award

Easy to light and easy to use, StoveTec Stoves make cooking with wood or charcoal effective and enjoyable. Cooks can boil 1 gallon (5 liters) of water in 20 minutes using just three 1.5 inch in diameter, 12 inch long sticks of wood (4 x 30 cm). One additional stick is enough to simmer for another 45 minutes. Designed and built to cook three meals a day, every day, StoveTec Stoves are durable and dependable.

Stove Features:
* 23,900 BTU of Cooking Power
* Rugged Cast Iron Stove Top Available in Multiple Sizes
* Easy-To-Clean Steel Body
* Sturdy, Heat Resistant Handles
Stove Includes:
* Steel Stick Support
* Adjustable Pot Skirt (fits pot sizes between 5” and 11”)

Prices:
* Wood Stove = $37
* Wood-Charcoal Stove = $40

This is a video of how to make a wood gas stove. A wood gas stove uses to stages of combustion. Stage 1 converts the wood to a gas, and stage 2 combustion the gas with the help of addition high temperature oxygen (or air) inlet near the gas combustion zone. The gas combustion zone is above the wood combustion zone.

Note, in the video, the two sets of vent holes—one set at the bottom of the outer (bean) can and one set at the top of the inner (soup) can. The bottom vent holes inlet air for both stages of combustion; a fraction of the inlet air passes directly into the bottom of the inner can and is used for combustion of the wood (stage 1), while the reaming fraction of the inlet air is heated as it passes up between the walls of inner and out cans, and finally through the top vent hole of the inner can. This is the high temperature air is what drives the stage 2 combustion process.

Some models use a small fan to “force” inlet air. Wood-gasification is one of the cleanest forms of combustion because it not only combusts the wood, but it subsequently combusts the gas produced from the initial combustion of the wood. This gas usually contains several pollutants, so when the gas is combusted, many of the pollutants get destroyed. Also, these stoves produce extremely high temperatures and are therefore very efficient.

Commonly referred to as wood gasifiers or wood-gas stoves.

This video is a collection of 12 rocket stove mass heaters. A rocket stove is more efficient, less polluting alternative to most traditional stoves found in developing communities. A rocket stove mass heater is the former with the addition of a longer exhaust system used to perform two functions: (1) to exhaust all the smoke from the stove fire and (2) to heat a thermal mass. Examples of 12 different thermal masses are illustrated in this video.
