You can cook a meal on literally a small handful of kindling. It takes just 15 minutes to boil 5 litres of water with only g of wood. The stove itself is extremely light at 1. This means you can really take it anywhere with you and there is even enough room in the bag for some wood and a pan.
Another amazing thing about the Horizon is that the outer cage on the stove stays cool while the stove is lit, meaning you can pick up your stove and carry it whenever you want.
Our Horizon is made from a high quality stainless steel, it's built to last and will be keeping you fed for years to come. We love the colour effect the heat leaves on the stainless steel: it reminds us of oil on water. They're also nigh-on unbreakable! Ours have survived rolling around in the back of a van, being used as a makeshift picnic stool not recommended but shouldn't do your stove any harm and generally taking a beating from years of beach, forest and wilderness-based adventures.
Now for the science! Pumice stone is a natural resource in Guatemala. It has a low density and there are air gaps in the stone itself. This air acts as an insulant meaning the heat operates directly on the plancha. An important feature of the Rocket Box stove itself is a grate for the wood to sit on inside the combustion chamber. This allows air to flow underneath the fuel. Without it the stove takes longer to heat and uses more fuel. Wood, charcoal, coal and other biomass are used by about 2.
In 'developing' countries, these fuels are often burned in open fires or poorly functioning stoves. Indoor smoke given off by these fuels contains constituents including small soot or dust particles that are able to penetrate deep into the lungs. Every year, indoor air pollution is responsible for the death of 1. Women and children being the ones most involved or exposed to this environment are worst affected. Charcoal production has been associated with environmental issues such as deforestation which further increases other environmental and social vulnerabilities.
The trees that grow most slowly; hardwood trees make the highest quality charcoal, furthering the impact. In places like Haiti , the limited availability of wood means that finding gathering fuel consumes time and energy, causes more severe weather, increases vulnerability, reducing capacity, costs money and further stresses an already depleted resource.
In some places such as in Mali, due to changes in the energy and economic sectors a pronounced shift from fuel wood to charcoal is happening which is raising concerns for the local resources. The main justifications for rocket stoves are economical, social, and environmental. Stove programs can produce economic benefits, saving time and money for the users. In urban areas where people purchase biomass fuel, the payback time for the cost of a rocket stove is short, thus saving on the cost of fuel.
Rocket stoves can help reduce the over-harvesting of trees. Improved indoor air quality and fuel efficiency have social and health benefits, especially for women and children. In order to reduce indoor air pollution, rocket stoves must improve combustion of the wood fuel, which means reducing the amount of smoke and harmful emissions produced during the burning process.
The key to efficient combustion is to burn wood at a high temperature, and there are several ways to achieve this:. A rocket stove consists of a combustion chamber where the fuel burns and a vertical chimney.
Part of what makes rocket stoves so efficient is that their vertical chimneys are insulated, meaning almost all of the heat moves upward. The vertical chimney is tall enough to ensure fuel fully combusts before the flames reach up to the cooking surface.
Rocket stoves most often appear as portable cookers, but large rocket stove cookers have their place in industrial kitchens. There is also the rocket stove heater, which forms a part of a rocket stove mass heating system in homes. The entrance to the first tube is where you put the fuel.
When you place the fuel into the feed tube, it begins to burn. The heat travels through the J shape of the rocket stove and exits from the vertical chimney, called appropriately the heat riser. According to the World Health Organization , 4. Inhaling smoke from a cooking fire is fine once in a while, but there can be severe health implications when it happens two to three times a day.
Significantly, a rocket stove produces no smoke, meaning these stoves are much better for the atmosphere and the lungs of the people cooking for their families. Beyond the health benefits, there are economic benefits inherent in the use of rocket stoves. In a talk given by Clark Semon at Williams College, he showed that rocket stoves are much more efficient than, for example, modern wood stoves.
Rocket stoves come in any imaginable size, from mini to large. To burn wood efficiently and fully combust fuel before the heat reaches the cooking area, the rocket stove needs minimum dimensions. A mini rocket stove can be as small as 8. This cute little stove would be perfect as a camping rocket stove, and there are mini rocket stoves that are even collapsible for maximum portability.
Rocket stove heaters are used to heat entire homes as slow-release radiant heating systems. These huge stoves can also be extended to water heating, cooking, and producing warm air for cold homes.
A rocket stove has many uses, including heating, cooking, water heating, and more. Most common is the portable rocket stove used for camping and other outdoor recreation activities. Rocket stoves are very efficient at combusting fuel namely, wood , and as such, produce almost no smoke. This makes them great for cooking meals for which a smoky flavor would be undesirable.
