Research Center - Improved Stoves for the Developing World

Our Rocket Stove Editor’s note: we have a new design for a portable rocket stove here. Low-tech is the new high-tech, and the best example of the low-tech revolution is the miraculous rocket stove–a stove that makes it possible to cook with small twigs–no logs needed! Best of all rocket stoves are easy to build. We liked the idea so much that we decided to build a permanent one just off our back deck for entertaining and as a backup to our gas stove should an emergency take out our utilities. The rocket stove was developed for use in poor nations where wood used for cooking has led to the vast, wholesale, deforestation of large swaths of the earth’s surface. Before we built the rocket stove we considered making a cob oven, a mud domed wood fired oven in which you can cook bread and pizza. Staring at the bricks we had scavenged to build the base of cob oven, we realized that we could re-purpose them for a permanent backyard rocket stove that we would actually use. Here’s the materials we used:

Solar Energy, Solar Power, Solar Heating, Photovoltaics, solar e Build a Wood-burning Cookstove From a Steel Barrel by W. Wayne Robertson from the November/December, 2004 issue of Countryside & Small Stock Journal Many people are familiar with wood heaters made from steel barrels. This is a description of how to make a wood cook stove from a barrel. An effort has been made to keep it simple so that you will not need special skills like welding or forging. The only tools needed are a drill, a jigsaw (with hacksaw blade), tape measure, and simple hand tools. ...

Mr. Sun Solar Rocket Stove The Rocket Stove is a variety of wood-burning cooking stove. It is easy to construct, with low-cost materials. These are low-mass stoves designed to burn small pieces of wood very efficiently. Rocket Stoves use branches, twigs, small wood scraps, or just about any small combustible material. A related design, the Rocket Bread Oven, is constructed using two 55 gallon drums, one inside the other. Rocket Stoves operates roughly twice as efficiently, and substantially more cleanly, than the open fire cooking methods still used in many areas of the world. Because these qualities improve local air quality, and discourage deforestation, the rocket stove has attracted the attention of a number of Appropriate Technology concerns, which have deployed it in numerous third-world locales (notably, the Rwandan refugee camps). Key features Edit Problems Pollution When biomass, such as wood, is consumed completely in the burning process, it produces carbon dioxide (C02) and water vapor (H20) alone. Edit

Solar Water Heating Projects and Plans Solar water heating systems have a good economic payoff, and are manageable systems to install or build as a DIY project. Some of the solar water heating designs are very simple and low cost. You can save as much as $7000 by building your own system. There are just over one hundred projects with full construction details listed below -- all free. The projects range from simple batch heaters for warm climates through closed loop and drain back systems that will work in any climate. One of the systems is our own $1,000 solar water heating system that has provided a solar fraction in excess of 90% through our cold Montana winter. My thanks to the people who have built systems, and then taken the time to send in pictures and descriptions for others to use.

I didn't take many pictures, but the construction is pretty basic. I framed the collector box with 2"x6" lumber and 1/4" plywood, the size is about 26" x 8'. The pump came from Lowes and is the Garden Treasures MD170 fountain pump. We are real happy with our choice of the 150 gallon Rubbermaid stock tank for our tub. I am using 3 sheets of the 3/4" blue Styrofoam for the tank cover. I did spend about $400 on this project, but did already have some of the materials. Tank $120 Pump 30 Urethane ins 90 (with shipping) sheet insulation 50 CPVC 75 I had most of the wood already, used sections of a old water hose between tank and collector, with pool noodles for insulation. I'm sure I left out some details, so feel free to ask questions. Brian And, the this note on performance from Brian: Was in the hot tub last night at 110 deg, still 106 tonight without running it today.

The Simple Art of Making an Earth Oven An oven is just a hole in the ground – light a fire, heat it up, and bake! An earthen oven is about that complicated. If you made mud pies when you were a kid, you can make a beautiful mud oven. You can also do it for nothing (or next to it), and it will work as well as a custom-built masonry or ceramic model costing thousands. Earth is not only more common, safe, cheap, and easier than brick, it's also more environmentally friendly and, I think, beautiful. The three basic steps to oven-making are: Make a pile of damp sand, and pat into a hemisphere.Cover with a layer or three of mud.Cut out a doorway and remove the sand. If you fire-dry it, you can bake tomorrow. Details: The floor: brick is a common choice – new, old, red brick, or firebrick.The mud: In most places, there is clay subsoil below the topsoil. Tools & Materials Finding Clay Subsoil Clay subsoil is pretty easy to recognize. When dry, the clay should be hard, not crumbly. Your Oven Floor Make A Sand Form - Shape The Void Mix Mud

Rocket Lorena Stove The rocket-lorena stove is a 2 pot rest stove and has an efficient conversion chamber which requires very little fuel. It has a firewood chamber and a chimney which further improves efficient burning. It can be made from locally available materials and so is affordable It is a great improvement over the normal three stone stove, that is common in villages, because of the vastly reduced fuel consumption, it simplicity to use and the short time it takes to cook food. Its disadvantages are that it is less portable than the three stone stove and occupies a larger space. [edit] Materials and Requirements Clay or Anthill Soils - 4 wheelbarrows Sand, alternatively silt run off - 1 wheelbarrow Sawdust, alternatively rice husks, coffee husks, cotton seed husks, dried grass, dung - 1 wheelbarrow Bricks or large stones - approx 20 Material for firewood shelf - thin metallic steel or fired clay slab Water - as appropriate for wetness of soil Wheelbarrow is useful for measurements [edit] Method

Muffin Fan Based Tin Can Wood Gas Camp Stove » Powerhouse Electronics Wood Gas Camp Stove - G4 Yet another tin can wood stove, I know, I know. Still, I’ve discovered a few things that may make your next stove build a little easier. What follows below are my trials and tribulations at build a really good working camp stove. Note, I’m still experimenting with certain aspects of the design. My inspiration came from an article in Make Magazine which described building a tin can wood gas camp stove. Now for a few negative comments about wood gas camp stoves. I don’t mean to be too negative. Tin Can Wood Gas Stove Examples This picture shows the four generations of wood stoves I went through until I ended on the final design (right most stove in the picture above – the Gen. 4). I could drone on and on about stoves 1 through 3 but I’m guessing you really just want to know about the final results. A natural draft style stove stinks – literally. I suggest you click on an image below to open the slide-show. The end…

RECYCLE A REFRIGERATOR INTO A SOLAR WATER HEATER Related Content CD and DVD Recycling The CD Recycling Center of America announced that it has chosen the United States Postal Service as ... Design and instruction about how to recycle a refrigerator into a solar water heater. Recycle a Refrigerator Into a Solar Water Heater Everyone knows that refrigerators are good for storing cold. Ever go riding or walking through the countryside . . . and discover an old, abandoned Frigidaire, Kelvinator, or what-have-you just sitting there collecting dirt, leaves, and field mice? For a while, I felt good knowing that I was helping to clean up the countryside, and recycle tons of valuable metals (thereby reducing the need for mining). "Surely," I said to myself, "there must be some useful function that a precision-made, well insulated 'cabinet' can serve." The Solar Water Collector The "shell" of the collector was easy enough to make: All I did was nail together a 5 inch by 2 foot by 4 foot box out of scrap lumber and wood paneling. OK. Miles K.

Build a rocket stove for home heating | IWillTry.org Author’s note, 2015-02-14: Based on the interest I’ve received in this project, I’m considering selling plans for a stove similar to the one described in this article. See the Rocket Stove Plans section at the end of the article and let me know if you’d be interested. Original article: For some time I’ve been considering the best way to deal with a pile of scrap wood that has been growing next to my home, the result of many woodworking and carpentry projects I’ve been involved in over the years. taking it to the landfillcutting it into chips and using it as mulchburning it From a climate change standpoint, the latter of these is surprisingly the least harmful in the long run. Burning also has a side benefit. Ads by Google Warnings Fire is dangerous. 0. 1. 2. 3. 4. How is a rocket stove different from a regular wood stove? The following illustration shows the basic design.
