Agriculture
Chicken Tractor
A chicken tractor is a movable floorless chicken coop for the purposes of pest control, lawn care, fertilization, and sheltering the chickens. When compared to traditional chicken coops the chicken tractor is far superior in many ways. The chicken tractor is a large step towards sustainable farming, and solves many of the problems that are presented by traditional coops and buildings used to house chickens. A chicken tractor is a bottomless, portable shelter-pen that fits over your garden beds. The chickens peck and scratch the soil, eat pest bugs and weed seeds, and fertilize the beds with their manure. Best of all, they provide eggs and meat.

SALT (Sloping Agricultural Land Technology)
SALT (Sloping Agricultural Land Technology) with emphasis on forage and animal production. This method is designed to allow crops to be grown even on steep hillsides with minimal erosion while at the same time increasing soil fertility and providing fodder for livestock. Rather than controlling erosion with rock terraces or ditches, SALT relies on rows of vegetation. Trees and shrubs with the ability to grow very closely together and to resprout when cut back are planted only inches/centimeters apart on the contour of the land. They are never allowed to grow too tall. Pruned branches are either left in the field as mulch or fed to animals, with manure returned to the field. After a heavy rain, the water is slowed down as it passes through the barrier. Many of the soil particles carried by runoff water are dropped, resulting in a gradual buildup of a somewhat flattened area on the uphill side.
Neem Tree as natural pesticide
Neem seeds and leaves contain many compounds which are useful for pest control. Unlike chemical insecticides, Neem compounds work on the insect’s hormonal system, not on the digestive or nervous system so they do not lead to development of resistance in future generations. These compounds belong to a general class of natural products called ‘limonoids’. The presence of the trees themselves are also helpful to repel mosquitoes.
Above-ground or Rooftop Gardens
A successful technique used in areas where gardens may benefit from being out of the ground due to factors like flooding; roaming chickens, iguanas, or goats; extremely poor or acidic or alkaline soil; or simply the ease of working at gardens that are raised to waist or chest height. ECHO have seen above-ground gardening methods used from rural Haiti (where raised tires kept chickens from ruining gardens), to the rocky soils of the Bahamas, to very urban settings like St. Petersburg, Russia, where rooftops may be the only space available for growing.
Making Bone Meal Fertilizer
Bones were used as fertilizer in England as early as 1653. ECHO featured ways to make a quality phosphate fertilizer from bones, called bone meal. An inexpensive low-technology method of making bone meal is called "trench-firing." The meal is equal to the best quality steamed bone meal, which is often imported at high prices.
Bicimolino Bike Mill

Mud Dip for Roots When Transplanting
ECHO reports: Eddie Visser in Guatemala wrote, "While transplanting citrus and leucaena seedlings into the ground, the soil would sometimes crumble off, leaving the roots of the transplant exposed. When this happened we dipped the roots into a mud solution, so that the mud adhered to the roots. Almost all the transplants we did this to are still living. The ones we did not do this to died." Timothy Volk with MCC in Nigeria later wrote, "I recently was on a study tour in Togo and saw villagers doing the same thing. However, rather than using mud alone, they also mix in some cow manure and sand. We were able to see that the seedlings (leucaena mostly) did not dry out during the day and that seedlings planted earlier were doing very well despite a poor rainy season. In addition the manure provides a small amount of nutrients to promote early root growth."
Water Mills Centre for Rural Technology, Nepal
The Centre for Rural Technology, Nepal (CRT/N), with support from the Government of Nepal and the Netherlands Government, runs a programme to upgrade traditional water mills, so that they work more efficiently, can operate for a longer period of the year, and also be used for other activities apart from grinding. Millers with improved water mills can earn more income and have extra time for other purposes. The flour produced from water mills is of better quality than from diesel mills, because it does not get so hot during grinding.

Urine as Fertilizer
Every day, gardeners across the world flush away a valuable and sustainable source of fertilizer for their plants -- urine. Urine is a good source of nitrogen and other minerals and, providing it is used correctly, is completely safe. Using urine as a fertilizer saves money, fossil fuels (used extensively in the production of chemical fertilizers) and water (no need to flush!). Using urine also cuts down on river pollution -- urine is a major source of nitrogen that contributes to river eutrophication if expensive denitrification is not used at the water treatment plant. And it's not a backwards step, it's space age technology -- NASA has used urine in hydroponics systems! The golden rule with urine use is to keep it separate from other bodily wastes. Urine is clean and needs to be kept that way. Pee in a bottle, or invest in a urine-separating toilet. Use it fresh. We all know that stale urine smells. That's ammonia, and it's made from nitrogen. The smellier your collected urine, the less nutritious it will be for your plants, as well as being unpleasant to apply. It is good practice when watering not too splash the leaves, but to water at the roots. This saves on evaporation, and dry leaves are much more resistant to disease. The plants that will benefit most from urine fertilizer are the ones with the highest nitrogen requirements. Try it on leafy vegetables like cabbages and cauliflowers, corn, or anything that needs a quick pick-me-up. Urine is too strong to be used neat on plants. Dilute at least 5:1, and it can be diluted up to 10:1 for use on tender plants and seedlings. Urine can also be salty, and using too much of it in one place can harm plants. Use it throughout your garden so that no one area suffers from an overdose, and don't use it every time you water a plant. Although neat urine is too strong to be used directly on plants, it can be used as a weedkiller; a few applications, especially if used on hot days, should kill your weeds. It can also be used neat as a winter spray for fruit trees, to discourage fungal diseases. A final use for urine in the garden is as a compost activator. The nitrogen in urine will speed up the composting process and kick start a slumbering heap.
Fertilizer Urine Bank (Urea fertilizer)
As increasing number of farmers in Siddhipur have started using urine as a fertiliser, because it yields good growth results while the crops require noticeably less chemical pesticides. As a result there is enough demand in the village for the urine and all of it will be used as long as it can be bought from a central point. In order to facilitate this a central collection tank has been installed, and a user committee has been established. For the collection the user committee employs one person equipped with a bicycle, and this collector is paid 50% of the revenue from the sales of the fertiliser. The remaining half is used to set up a maintenance fund. Full article and details below.
Bee keeping and Top Bar Hives
Beekeeping has a very important role to play in the development of Kenya and other African countries. Pollination is the most important but often unseen benefit. Pollination is the transfer of pollen from the male to the female part of the flower resulting in fertilization. Bees are good pollinators and many flowering plants depend on insects, such as bees, to transfer pollen. Inadequate pollination results in low yields of uneven and small fruits. It is estimated that more than 75% of the crops in warmer countries, such as Kenya, benefit from bee pollination. The other main benefit of beekeeping is the production of products such as honey and beeswax which are a valuable source of income for small-holder farmers. Beekeeping is also a valuable source of income for pastoralist communities in Kenya's Arid and Semi Arid Lands (ASAL's). People living in ASAL's are among Kenya's poorest. Beekeeping also has a very important role to play in protecting Kenya's natural environment and gives communities economic benefits from standing trees. As a group, beekeepers have a vested interest in protecting trees - the source of their honey.

Small Scale Hydroelectric Power
AIDG (Appropriate Infrastructure Development Group) presents a Micro-hydroelectric power, whose installations are commonly known as "run of the river," have a few big differences when compared to the giant installations found throughout the developed world.
The "Salchica" Biodigester
Biodigesters are an excellent technological solution for families and farmers that want a combined sanitation and energy solution, who can manage the daily feeding required to produce adequate biogas, and who have use for lots of fertilizer. The polyethylene tube biodigester or "salchicha" type digester has become increasing popular in developing countries, due to its low cost and ease of manufacture and installation. AIDG's basic polyethylene plug-flow digester is a small-scale system aimed at low-income rural families. The salchicha biodigester consists of a sealed flexible plastic tube about one meter in diameter and between five and ten meters in length with PVC pipes in both ends. One pipe serves as the waste entrance; the other is the fertilizer exit. At the highest point of the tube, in the center, a flexible hose is connected which pipes the gas to the kitchen or wherever it will be consumed. The digester is empty of technology inside; everything that happens is a natural process which the biodigester simply takes advantage of.
Axial Flux Windmill
The primary design utilized by the AIDG is a wood blade, automobile brake drum rotor spindle windmill, that can produce as much as 1,200 watts in high winds and starts producing in a slight 5mph breeze. This is an extremely rugged simple design adapted from those of Hugh Piggott and Otherpower.com. The primary rotor comes from an automobile wheel spindle and thus is well suited for spinning at high revolutions under heavy strain for years on end. The coils are wound and connected in star formation for 110 volt AC output which is then rectified for battery charging. The blades are carved out of 2X10s and are easily replaceable in case of damage.
Biodigester Design & Construction
The biodigester design that the Santa Fe Women's Group used is a fairly simple and inexpensive one. A few of the tasks, like digging the hole, may be quite labor-intensive, and some of the tasks require certain skills, like creating cement walls and laying cement block, but the cost of the materials is relatively modest at around $300 US in Costa Rica, and the construction time is fairly short at about one week. Below is a list of the most essential materials that the Santa Fe Women's Group used for its biodigesters. In order to facilitate a good understanding of the instructions later on, all of the materials in the list include a brief description of their roles in a functioning biodigester. Some of the materials not included in the list are not as essential and can be replaced by other parts that are more convenient for your particular situation. These options will be explained as we go along. Website has photos and detailed instructions
Kisangani Smith Group - Home sawdust stoves
KSG has developed two types of ‘Rafiki wa mazingira’ (environmentally friendly) cooking stoves, which can be made by blacksmiths using hand tools. Since 2005, over 3,500 stoves have been made and sold by KSG and its trainees. The first is an innovative stove made by hand from sheet metal. This stove burns sawdust, which is readily available as waste from the timber and furniture industry in Njombe. Elsewhere in Tanzania it is also used with rice husks and other agricultural residues. When filled with packed sawdust, the stove can burn steadily for up to six hours. Users like the stove because it cooks quickly and cleanly, needs little attention, and above all saves money. A stove costing 35,000 TSh (£16) can save a family over 10,000 TSh (£4.50) per month from purchasing charcoal. Thus the stove pays for itself in three or four months.
SKG Sangha - Biogas for cooking plus vermiculture
In 1993, moved by his own experience of watching his mother cook on an open fire and suffer from itchy eyes and a bad cough, Mr D. Vidya Sagar set up SKG Sangha with the express aim of providing rural women in Karnataka with an alternative energy source to firewood for cooking. After researching available options, Vidya Sagar chose the 'Deenbandu' cow dung based biogas plant as the most reliable and cheapest alternative and, with the help of a bank loan, began building and supplying these plants to rural households. Since 1993 SKG Sangha has installed over 43,000 of these biogas plants, which is the highest number of plants installed by a single organisation, certainly in India and probably in most other parts of the world as well.
Biotech, India Turning food waste into gas
In order to have a real impact on the waste problem in Kerala, India and to produce significant amounts of clean energy, BIOTECH has developed biogas digesters that are not only suitable for domestic use but also for schools and hostels and larger municipal sites. To date BIOTECH has built and installed 12,000 domestic plants, 220 institutional plants and 17 municipal plants that uses waste from the municipal fish markets to produce biogas which is then used in a 3kW engine to generate electricity for lighting the market. Around 160 of the domestic plants installed also use waste from 'eco-friendly' toilets. Using excreta in the digesters helps manage human waste at source and avoids ground water contamination. BIOTECH'S use of latrines is considered to be a major breakthrough in combating water and air-pollution. Mrs Anna Benedict from Kumbalangi island panchayat, comments: "Before we had the plant, all the waste went into the sea. Now we have a latrine and biogas plant, the waste is treated properly."
Biogas Appro. Rural Technology Institute, India
The Appropriate Rural Technology Institute (ARTI) in Pune has developed a biogas plant which uses food waste rather than manure as feedstock and supplies biogas for cooking. The plant is sufficiently compact to be used by urban households, and over 700 are currently in use.
DAXU Stoves designed to burn crop waste - China
The Daxu stove model has proved so efficient that it was singled out for achieving the highest efficiency of any entrant in a stove competition organised by the China Association for Rural Energy Industries and the Shell Foundation. To date, 25,000 Daxu stoves have been sold with 10,000 having been sold in the first three months of 2007. These sales are due in part to subsidies provided by the Yangqing County authorities in a drive to combat deforestation and indoor air pollution in a region with an abundant source of crop waste. The Daxu stove is specifically designed to use either loose or compressed crop waste as well as wood. The stove is over 40% efficient and produces hardly any smoke. This is achieved by burning the fuel using a controlled supply of air that produces gas which then rises to meet 'secondary' air causing the fuel to burn more thoroughly. This ensures that the fuel burns more efficiently and that heat is transferred to the pots more quickly which allows a meal to be cooked in 15 -20 minutes with minimal smoke pollution.
Ecotricity, UK Windpower
Ecotricity, a fast-growing installer of wind turbines in the UK, has played a significant part in boosting the wind sector here as well as helping the UK meet its targets for electricity generation from renewable energy.

Adjustable Glasses
Inventor, Joshua Silver's provides a simple solution for correcting vision at the lowest cost possible -- adjustable, liquid-filled lenses. The affordable eyeglasses have a ultra-utilitarian spectacle design relies on the principle that the fatter the lens, the more powerful it becomes. The lenses are filled with liquid, and can be adjusted to different strengths by adding or removing fluid from tiny syringes on each arm, then locked to the right strength. More than 30,000 of his lenses have been distributed in 15 countries, and a new model will scale that number up to millions. impairments exist in every country in the world. There are two parts. A reservoir filled with fluid and the glass chamber. They are connected through a type of syringe technology. The "glass" is a chamber with a plastic flexible membrane on both sides. When the user wants to adjust the lens he turns a knob which either forces fluid into the chamber or removes fluid. If the user is far sighted, the extra fluid filled chamber is convex. If the user is near sighted, the removal of fluid causes a concave shape.

VisionSpring will also introduce its products to retail chains that have begun to serve low-income areas in the developing world, bringing clear vision and increased economic productivity to millions of people who currently suffer from a loss of near vision and a lack of access to affordable glasses and proper eye care. VisionSpring has sold over 100,000 pairs of affordable glasses, trained over 1,100 Vision Entrepreneurs, and referred over 90,000 people for advanced eye care.
Zambulance
The Zambulance is an affordable transport option for remote areas in developing countries. In several developing countries, people die from treatable diseases simply because they cannot reach health centers when they need it most. Bicycle ambulances are a proven solution to this transport barrier in remote areas where current methods of transport are insufficient in speed, safety, cost, or availability. Since July 2005, Jessica Vechakul has been collaborating with Disacare Wheelchair Center in Lusaka to develop the Zambulance, a bicycle ambulance that can be locally produced from common steel and bicycle components. The ambulance is designed to reduce preventable deaths in places where motorized ambulances cannot access, including most villages. The ambulances consist of a trailer that is attached to a bicycle. Because they do not require money for fuel and maintenance is very simple (simpler than bicycle maintenance), these ambulances are ready to use at any time. Bicycle ambulances are intended for use by rural hospitals, clinics, and village (under the management of the village council or chief) and home based care providers. Read More....

Composting Latrines
Composting latrines benefit local agriculture by creating a safe, renewable source of fertile compost from human waste. In their simplest form a tree is planted on a filled latrine pit - however a twin pit latrine offers a more permanent solution. One pit is used at a time, and after each use soil and ash is added to dry the contents out. Once it is full a further layer of soil and ash is placed on top and the pit is covered. The second pit is then used until it too is full. At this time the first pit is dug out and its contents used for compost or, if not enough time has passed, it is moved to a secondary compost point.

Solar Oven
This efficient solar oven sets up quickly and cooks efficiently without the use of cooking fuels. Includes water sterilization indicator device.
Jiko Sawdust Stove
In countries where forests are depleted, wood becomes scarce and expensive, raising the cost of both wood and charcoal. These sawdust Jikos use less expensive fuel, sawdust and other biomass, such as husks. According to one orphanage, "The jikos are helping us a great deal. We use much less money on sawdust than we use on firewood. We spend about 400 shillings worth of sawdust in a day compared to 2,300 we used to spend" They are working well enough that the school is looking into buying two more.

Berkley-Darfur Stoves Project
The Berkeley-Darfur Stove is more than a stove. It equates to safety, improved nutrition, the opportunity to earn an income and the chance the environment needs to recover. It's an awful lot for a small stove to promise but the Berkeley-Darfur Stove delivers. Because of the efficiency of the stove – four times more efficient than traditional 3-stone fires and two times more efficient than clay stoves. This stove fully encloses the open flames, and thus substantially reduces the danger of the dense straw-and-stick shelters burning down because of open fire cooking. The stove produces much less smoke and thus reduces smoke inhalation in the cramped shelters during indoor cooking.
Pot-in-Pot Cooler
The Pot-in-Pot system consists of two pots, a smaller earthenware pot nestled within another pot, with the space in between filled with sand and water. When that water evaporates, it pulls heat from the interior of the smaller pot, in which vegetables and fruits can be kept. In rural Nigeria, many farmers lack transportation, water, and electricity, but one of their biggest problems is the inability to preserve their crops. With the Pot-in-Pot, tomatoes last for twenty-one days, rather than two or three days without this technology. Fresher produce can be sold at the market, generating more income for the farmers.
Heifer International
Heifer envisions… A world of communities living together in peace and equitably sharing the resources of a healthy planet. Heifer’s mission is… To work with communities to end hunger and poverty and to care for the earth.

Sanitation
Pee Poople Sanitary Disposal System
The Peepoo is a personal single use toilet, that sanitizes human excreta shortly after defecation, preventing the faeces from contaminating the immediate and larger environment. The toilet is a high technology product for a low economy. As with the original Tetra-Pak, it uses a minimum of material while providing maximum hygiene. Recognizing consumer needs, the Peepoo is formulated from a bottom up perspective putting the user’s need first. Ergonomically designed to be easy and hygienic to use, simple and rational to produce, and thus possible to be sold to groups with the weakest purchasing power, the Peepoo offers a sanitation choice for both individuals and society at large.
Laundry Detergent Formula
Proper sanitation can prevent disease and illness. This detergent is biodegradeable and only a few cents per load of laundry.
Community Toilet Linked Biogas Plant
Recycling and reuse of human excreta for biogas generation is an important way to handle the health hazards from human excreta, while leveraging beneficial byproducts. Sulabh is the pioneering organization in the field of biogas generation from public toilet complexes. After a series of experiments, the organisation developed a more efficient design of biogas plant that has been approved by the Ministry of Non-conventional.
Sulabh Effluent Treatment System
Sulabh developed a new and convenient technology by which the effluent of human excreta based biogas plant turns into a colourless, odourless and pathogen-free liquid manure. The technology is based on filtration of effluent through activated charcoal followed by ultraviolet rays. The filtration unit makes it colourless, odourless and free from organic particles and the UV eliminates the bacteria. It reduces BOD and COD of the waste water drastically. Since such wastewater is from human wastes, its BOD (Biochemical Oxygen Demand) which is around 200 mg/l, comes down to <10 mg/l after treatment – safe for aquaculture, agriculture gardening or discharge into any water body. It can also be used for floor cleaning of public toilets in drought prone areas.
Sulabh International Social Service Organisation
Sulabh technologies for on-site sanitation provide cost-effective, eco-friendly sanitation solutions with complete recycling for human waste disposal and prevent open-defecation. They provide access to sanitation facilities to millions of people in India. They can be replicated anywhere in urban or rural areas, towards meeting the Millennium Development Goal on Water and Sanitation.
Biodegradable Waste Composter
The Sulabh International Academy of Environmental Sanitation has developed a new technology – Sulabh Thermophilic Aerobic Composter (STAC) which requires only 8 to 10 days to make compost from any biodegradable waste, without any manual handling during composting. It is based on the thermophilic aerobic method. The technology does not require recurring expenditure. The plant is fabricated from G.I. sheets having double walls filled with glass wool, and partitioned with perforated sheets into three chambers. After biodegradation, the liquid is collected in the bottom chamber and can be removed and used for agricultural / horticultural purposes. Manure which contains 30- 35% moisture, can be directly used for agriculture / land filling purposes or dried, granulated and stored until further use

Safe Haven Bathhouse Ban Tha Song Yang, Thailand
An innovative bathhouse design that basic needs like toilets, personal hygiene and laundry. A simple structure was already built and became the framework for the project. The most intimate functions are located in the two separate parts of plastered concrete blocks. In the central area you find a space for bathing that opens up towards the vast teak plantation. The bathing area is only partly privatized, adapted to Karen culture. A tilted facade of bamboo covers the front of the building and creates a passage, tying the functions together.
Urinal System Designed by TYIN
Part of a TYIN innovative Safe Haven bathhouse design in Ban Tha Song Yang, Thailand (see http://clayforearth.org/solution.php?id=301) which fills basic needs like toilets, personal hygiene and laundry. A simple structure was already built and became the framework for the project. The most intimate functions are located in the two separate parts of plastered concrete blocks. Urinals utilized re-purposed tires with pipes connected to them. In this design the urine runs down through these pipes and into the ground. Approx. 10 meters away from (and 1,5 meters below) the bathhouse, the pipes are perforated. So little by little the urin is filtered directly into the ground. An alternative to this would be to direct the urine into a catchment systems to utilize the urine for fertilizer (see solution.http://clayforearth.org/solution.php?id=305) The ground at Safe Haven however is mostly rock and dry soil, so the original solution has proven successful. The urine-pipes also have vertical pipes connected to them, so that the (smelly and warm) air inside the pipes disappear. You can see these pipes on some of the pictures.

Tippy Tap Hand Washing Device
A plastic container with a small hole near the lid is suspended on a stick through the handle, which can be tipped by a piece of wire or string attached to the lid. The string is attached to a piece of wood on the ground, which tips the can if you stand on it. When tipped, the can dispenses a small amount of water, about 70ml, just enough for a clean hand wash. Compare that with the 500 ml of water for an average hand wash. When you remove your foot, the can swings back to its original position. A piece of soap is suspended by a string next to the can. It is so hygienic that it would even qualify for surgeons -- a foot-operated water dispenser in which you only touch the soap! A gravel bed is used to soak away the water and prevent mosquitos. When the container is empty, the cap is unscrewed and the container is removed from the stick. The container is then filled again at a water pump, and reassembled.

Solar
Solanterns Solar Lanterns in Kenya
Our lanterns retail for ksh. 2,000 and have a battery life of 3yrs before the battery needs replacing. So very conservatively, that is ksh. 666.00 a year for lighting compared to ksh 3,650 per year using kerosene lanterns and assuming an average ksh. 10 per night worth of kerosene use. Said another way, a family can buy a solar lantern with the same amount of money they spend on kerosene in 200 days. Which means that until the battery needs replacing, they have free, high quality, environmentally clean and safe lighting solution.

Rainwater Harvesting
Falling rainwater is some of the cleanest naturally occurring water available and where it falls regularly there is scope to collect it, before evaporation takes place and before it becomes contaminated. This is called rainwater harvesting. Water is generally collected from pre-cleaned roofs, where it runs via guttering into a storage tank.
Ram Water Pump
amp pumps are affordable, durable and reliable The ram pumps used by the AIDG are manufactured using supplies available at any plumbing store, which makes them far more economical for rural families and also ensures ease of replication wherever the pumps are needed. Because ramp pumps have few moving parts, they are easy to maintain, very reliable and have a long operation life. The capacity exists to manufacture large custom pumps for installations with big flows or big elevation changes in which the standard pumps can't do the job. A ram pump installation consists of four typical components: 1. A water source uphill of the ram pump, 2. A pipe, which carries the water from this source to the pump 3. The ram pump itself, and 4. Another pipe which carries the water to its point of use. As the water runs downhill from the source to the ram pump, it gains force and velocity. When this velocity reaches a determined point, the water closes a valve in the ram pump known as the "impulse" or "waste" valve. The force of the water against the now closed impulse valve causes pressure to build inside the pump. The water sends high-pressure shock waves in all directions (the "water hammer," or "ariete" in Spanish, from which the pump gets its Spanish name, "Bomba de Ariete"). These shock waves open another valve, the delivery check valve, and water squirts through reaching altitudes of up to ten times greater than the vertical distance from the water's source to the pump. An air vessel installed in the pump acts as a kind of regulator which keeps the flow at the top steady, instead of delivered in bursts, as the pump internally functions.
Slow Sand Filtration
Slow sand filtration is an inexpensive chemical-free method of water purification. For communities with access to sand, this filtration technique is one of the most cost effective and environmentally friendly forms of water treatment available.
Q Drum Rolling Water Container
A cylindrical water container that makes transporting water faster and easier. The idea of the Q Drum originated in response to the needs of rural people in developing countries who have a problem carrying adequate quantities of potable water from a reliable source. A burden which is generally bestowed on the women and children of each community. In Africa for example, many debilitating back and neck injuries are a result of women carrying heavy loads on their heads. Millions around the world, especially in rural Africa, live kilometers from a reliable source of clean water, leaving them vulnerable to cholera, dysentery, and other water-borne diseases. Water in adequate quantities is too heavy to carry. The Q Drum is a durable container designed to roll easily, and can transport seventy-five liters of clean and potable water. Rolling the water in a cylindrical container, rather than lifting and carrying it, eases the burden of bringing water to those who need it. DESIGNER: P. J. and J. P. S.

Ceramic Water Purifier
Since 1998, Potters for Peace has been assisting in the production worldwide of a low-tech, low-cost, colloidal silver-enhanced ceramic water purifier (CWP). Field experience and clinical test results have shown this filter to effectively eliminate approximately 99.88% of most water born disease agents. It is a simple, pressed bucket shape 11” wide by 10” deep, made with a mix of local terra-cotta clay and sawdust or other combustible, such as rice husks. The simplest press utilizes a hand-operated hydraulic truck jack and two-piece aluminum mold. After firing to about 860 deg. C. the filter is coated with colloidal silver. The combination of fine pore size, resulting from milled, screened materials, and the bactericidal properties of colloidal silver produce an effective filter. A 1.5 to 2.5 liter per hour rate of filtration is determined by the combination of clay/combustible mix and firing temperature. For use the fired, treated filter element is placed in a five gallon plastic or ceramic receptacle with a lid and faucet. Pricing for ready to use filter units is determined by local production costs and is usually between $15-25 with the basic plastic receptacle. Replacement filter elements will cost $4 to $6. A basic production facility with three or four workers can produce about fifty filters a day. Potters for Peace shares their design as open source, they do not sell nor distribute the pots.
Filtron Ceramic Water Filter
The Filtron is a household point of use water filter capable of removing 99.9% bacteria. Potters for Peace offers a training and production set up package to local partners who can assume long term responsibility for quality control, marketing and user followup.
