Vuthisa Technologies have scoured the planet looking for products we feel can change lives in the developing world and we are proud to be associated with the following products, manufacturers and institutions:
EcoZoom Stoves burn cleaner, use less fuel, and are more economical than any other stove of their kind. It’s based on the rocket stove design principle, invented by Dr. Larry Winiarski from Aprovecho Research Center (ARC) USA. The StoveTec range of stoves was launched in 2008 and Aprovecho won the prestigious Ashden International Energy Champion Award for 2009. StoveTec (rebranded EcoZoom in South Africa) have disseminated over 100,000 stoves to impoverished communities in the last year alone.
“Many villages have very smoky kitchens and this has a negative impact on worker morale and performance….”
We are advocating a way of life reminiscent of simpler times where wood stoves were a common sight before LPG or paraffin stoves or even before electric stoves, but with increased efficiency and fewer pollutants. The knowledge of fire-making extends back some 400,000 years and we must not underestimate the cultural importance of having a visible flame inside a home not only for the purposes of cooking and heating, but to serve as a gathering point for all members of the family to congregate and bond as a family. Couple that fact with the alarming increase in costs associated with electricity and other cooking fuels and you have a winning combination. Apart from monetary savings, these types of advances in stove technology have seen an increase in the health and overall well-being of the stove users and their families. Many villages have very smoky kitchens and this has a negative impact on worker morale and performance. Indoor smoke inhalation gives rise to pneumonia and other respiratory infections – the biggest killer of children under five years of age. Indoor air pollution (IAP) is responsible for nearly half of the more than 2 million deaths each year that are caused by acute respiratory infections (ARI). Good ventilation and improved cooking stoves can dramatically reduce children’s exposure to smoke.
The ceramic-lined EcoZoom (Rebranded in South Africa) stove is very fuel-efficient (conserves wood) and emits 70% less smoke. It can also be quite costly to maintain or replace old-fashioned metal and cast-iron stoves. We recommend that these old stoves are replaced with 3 EcoZoom stoves, cemented into a docking station, effectively creating a 3-pot stove at 30% of the cost of replacing or repairing a worn out stove model. A smoke hood is then installed above the stoves to guide emissions, especially at start-up, out of the home. Alternatively the Plancha which has a cast iron cooking top and external chimney comprising two EcoZoom stoves may be more appealing to higher end homes.
Vuthisa was recognized for the work it did in promoting clean burning cookstoves and was recently added as member number 568 of the prestigious Partnership For Clean Indoor Air (PCIA). The Partnership for Clean Indoor Air was launched at the World Summit on Sustainable Development in Johannesburg in September 2002 to address the increased environmental health risk faced by three billion people who burn traditional biomass fuels indoors for cooking and heating. This voluntary Partnership brings together governments, public and private organizations, multilateral institutions, industry, and others to increase the use of affordable, reliable, clean, efficient, and safe home cooking and heating practices. The mission of the Partnership for Clean Indoor Air is to improve health, livelihood and quality of life by reducing exposure to air pollution, primarily among women and children, from household energy use.

Firewood dependence for cooking in the developing world has resulted in forests being depleted at a rate of 2.5 to 3% per year. It is here in the poorest parts of the world that villagers spend a good portion of their time gathering wood to cook, heat and make charcoal. To counter this dependence on wood, efforts were made in the early 80’s to come up with alternatives. One such alternative being explored was making fuel briquettes from non-woody biomass for cooking. Dr.Bryant and students at the University of Washington in the USA developed a novel low-cost briquette making process using non-woody agricultural residues, ordinary water and a hand-operated wood press.
“Anyone can make briquettes from their own leaves, grass, straw and paper”
The briquette process was simple and could be established in poor rural communities, requiring little technology and very little money. With a small effort villagers could now create their own fuelwood from agricultural residues. To make a briquette, ordinary leaves, grass and straw would be chopped and mashed into a paste. This paste would then be compressed into round cakes and dried. The resulting briquette would be sold as a fuelwood- and charcoal substitute at the local market. In 1994 the Legacy Foundation, USA, picked up on Bryant’s briquette making process and extended the outreach activities. Today, Legacy Foundation’s training and online media services have spread the briquette technology and process into eleven other countries, such as Haiti, Uganda, Mexico, Nepal, Kenya, Mali and Tanzania. The foundation has also released 8 technical/training manuals on all known aspects of briquette making. Vuthisa acquired the rights to promote and extend this technology into Southern Africa. Note that the Legacy Foundation have now launched their new Ratchet Press. This press is a high pressure, compact, easily assembled, transported operated and maintained briquette press. Using common tools and skills, the Ratchet Press can work for an individual or full time commercial briquette production facility. Though it is compact and portable, it can deliver nearly the same force as their larger Mini Bryant compound level wood press sold through the Legacy Foundation. They have launched 3 Ratchet Press manuals namely; Ratchet Press Construction, -User, and -Marketing manual.

“The Test Briquette Maker can be built for under $125 (USD) and requires almost no maintenance…”
Quite a large proportion of people that buy our manuals never commit themselves to building the actual presses, possibly due to time or money constraints or they lack workshop tools and/or technical know-how. The Test Briquette Maker can be built for under $125 (USD) and requires almost no maintenance, with only basic drilling and welding (10 cm at most) work required. If you’re looking to attract funding to roll out a program using this technology, this press will be most suitable to that end. As mentioned a FREE download link to the “Test Briquette Maker Construction and User Manual” will be supplied with every manual purchased on this site.

Hippo Water Roller
Approximately 10 000 communities throughout Southern Africa (15 million people) are currently without adequate access to water. Multitudes have to trek long distances to distant waterholes or wells to obtain their daily water needs. To address this problem, two south Africans, Mr. Pettie Petzer and Johan Jonker invented the first rolling drum to cart water, officially named the Hippo Water roller in 1993. The association with water, round body and thick skin compares well to the famous African Hippopotamus. The Hippo Water Roller improves access to water by rolling 90 litres (24 Gallons) along the ground saving time and energy as approximately 5 times more water can be transported. The daily burden of carrying heavy 20 litre buckets on the head is significantly reduced with this ‘appropriate technology’.
“Approximately 5 times more water can be transported”
The steel handle allows the roller to be pushed or pulled over difficult and very rough terrain. The overall width of the roller with handle attached was determined by measuring the average width of a standard doorway and sized to allow it to be pulled through freely. The steel handle is fitted with special polymer end-caps to reduce friction and wear and prolong the life of the pivot cavities in the drum. The roller is rounded at the shoulders to simplify tilting when wanting to pour from the full roller. However, the roller is also very stable in the upright position when it rests on a small, flat surface. The roller has hand grips at the bottom and top to make emptying the container easier.
Although the Hippo roller was mainly designed as a water-gathering aid for underprivileged communities, several other uses have since been discovered. Because of the Hippo water rollers’ water tightness it can act as a watertight container to keep valuables and clothes dry when going downstream in white water rapids on extreme excursions. It can also suffice as a container to be dropped with lifesaving contents from helicopters or low flying fixed-wing aircraft in flooded disaster areas. This might include food and medical supplies, warm dry clothing and blankets, and naturally, water. The polyethylene is lighter than water and will stay only partly submerged, even with fresh water in it. In fact, some rollers have been distributed pre-filled with grain or other foodstuff to villages.

What else do we offer?
We have developed two charcoal/biochar producing kilns namely the Trans-Portable Kiln and the 3-drum Biochar Retort, both of which we sell ‘made to order’ in South Africa with overnight delivery, as well as the digital Construction and User Manuals of these models:
In its simplest form the Trans-Portable Metal Kiln is a simple, heavy gauge, mild steel drum with a square lid for making charcoal. This system uses a ‘direct combustion method’, whereby the heat for carbonisation comes from burning a portion of the biomass feedstock in a limited air environment. A single kiln will produce approximately 80 kilograms of charcoal (from 0.7 m3 of wood) or 1.3 tons of charcoal (from 11 tons of wood) per month. Instead of increasing your carbon footprint and operating costs by transporting large amounts of timber to a stationary kiln, this kiln is simply rolled (by one person) to the already prepared and air-dried brush-pile. This drum can be bolted together (3 sections) for easy transport and DIY assembly.
The 3-drum Biochar Retort on the other hand, is more clean burning (with the added conical lid and chimney) and the burn is more controlled which gives the user the option to create either Biochar or conventional charcoal.

We do in-depth Working Plans (which includes tree samplings) for forestry companies.
Entrepreneurs need assistence from time to time with digital image maniplulation and 3D renderings for Prototypes, Patent drawings, Blogs, Brochures and Social Media tools. We help with that and can also raise the profile of a small businesses’ address through Google Earth and place digital versions of their products inside Google’s 3D warehouse.
We have been doing tree sampling enumerations for 17 years and use the Forest Inventory Planning System to calculate yields accurately. We have built up a reputation for accurately determining timber volumes for Pine, Gum and Wattle plantations. We provide:
1) A Plot Summary Report:
This report combined in one page summary format, contains information similar to that typically found on a compartment list as well as other useful information such as Average DBH; – Height, – S/ha; – Basal area; – MAI; – Volume/ha; – Volume/tree; Site index and Total Volume per compartment.
2) A Plot Volume Report:
This report displays the spread of diameters in 2cm diameter classes, the number of trees in each diameter class, the average height for trees in that compartment and other general plot information such as site index, MAI and basal area prior to utilisation, i.e. standing volume.
3) Products Report and Log Utilisation Report:
Wattle and Gum yields are expressed in a ‘Products Report’ i.e. Transmission Poles, Treated Poles, Mining Poles and Pulp.
Pine yields are contained in Sawlog Classes and Pulp.
We typically lay out circle plots (10 or 15 metre radius) and generally adopt a 1 plot per hectare philosophy and are able to sample between 25 and 45 ha per day, depending on terrain, species and stocking. If compartment areas are vague we can acquire Rectified Digital Imagery to calculate areas, without having to resort to using GPS. For more information kindly contact us here:
Need a plantation or farm map in a hurry? We serve all small farmers in South Africa with their mapping needs. We provide:
- Plantation maps
- Fire maps
- Standing timber maps
- Aerial photographs
We can draw up accurate maps, and determine areas (hectares) of any type of crop, including timber, sugarcane, jungle wattle and others, as well as delineate around open grassveld, conservation areas, dams, homesteads and identify primary and secondary roads. In some instances we are given GPS areas, which we are able to overlay onto or incorporate into the final map.
All we require is a farm name and title deed number and general location. It will be helpful, but not a requirement to be supplied an existing map or hand drawn delineation of compartment boundaries, accompanied by a compartment list. We will source the appropriate digital imagery of the area in question, which usually includes the most recent aerial photography (1:10 000) and a topographical map (1:50 000).

Today, 3D design is the heart of product innovation. It enables engineers and inventors to take ideas and fleeting concepts and turn them into physical products that deliver value. For many discrete manufacturers, revenue growth, product development efficiency, quality and cost reduction would not be possible without it. Compared to other CAD design houses we have less overheads and are able to offer a more affordable consulting rate. Over the years we have been able to develop several of our own products with 3D modeling software. So in a nutshell, we can create 3D objects from a 2D environment for display purposes on a pamphlet or website, or conceptualize a design from simple hand drawn 2D sketches. These 3D drawings can then be set out back into a product specification sheet, which is simple to follow by a light engineering works or architect.
We can also upload 3D models to a 3D Warehouse, a private or public viewing platform for your clients to view your products in 3D.
Please note Geo-modeling uploads to Google Earth has been retired on 1 October 2013 until further notice. An example of one of the Geo-models we uploaded to the 3D warehouse can be found here:
