There are a significant number of people who are making a concerted effort to live off-the-grid. One way is using a Rocket Stove. Wood serves as the fuel, and it is burned in a simple combustion chamber containing an insulated vertical chimney. This ensures almost complete combustion prior to the flames reaching the cooking surface, generating enough heat. Heat loss is minimal.

The rocket stove designs are most often used as portable stoves for cooking, but the design is also used to make rocket mass heaters for heating. The efficient burning device uses 18 to 35 percent less fuel compared to the traditional stoves. It also reduces fuel use by 39 to 47 percent compared to the traditional three stone fire mostly used in developing countries. When it comes to emissions, the rocket stove is further ahead than the traditional ones.



Because the rocket stoves burn at much higher temperatures than the standard woodstove or fireplace, it emits much cleaner exhaust fumes — unlike the traditional ones that emit pure smoke.

Apart from Engineer775 Practical Preppers, who is making use of the rocket stove, a blogger named Rob, who is also a woodworker, has installed the stove to help heat his home.

Rob explained on his blog page that he had an accumulation of small scrap wood in his workshop. And instead of sending it to the landfill, he decided to make use of the unwanted pieces of wood.

An idea occurred to him. He converted his old water tank to a rocket stove. Having gotten the stove, he filled it with small amounts of wood to build a fire in it and then had the heat he wanted in his home. The process is very simple and easy to follow, and will reduce electricity costs. Below is a video showing a rocket stove heater in action.



Apart from the rocket stove being recommended in the Western world for heating purposes, in the developing world too, the stove proves to be useful. The flexibility and the stove’s brutal efficiency have made them a popular choice in the developing world, replacing older conventional stoves that are smoky and inefficient.

We can make something useful with the little resources we have. There is no harm in trying. Let’s embrace these little technologies to make the most out of our lives.
