Agenda

Issues concerning developing countries and corresponding low-cost solutions

  • Sanitation
  • Water
  • Health

DESIGN FOR PEOPLE IN NEED

biolet s composting toilet
Won gold medal - International Inventors' Exhibition in Geneva

No water, no sewer and no chemicals

No odors - designed so that there is a constant air flow into the toilet

The compost - 9 times fewer fecal coliform bacteria than from other composting toilets - safer to handle

The compost could be used as a manure for non-food vegetation

BioLets can be installed anywhere - you don't need a water hook up

BioLet toilets do not require any pumping or outside holding tank

BioLet's Composting Toilet

dignity toilet contd
Dignity Toilet (contd…)
  • Cooler Solutions’- won international design competition - International HIDO (Humanitarian International Design Organization) Design Award
  • Portable sanitation solution - refugee camps, developing countries.
  • Solid waste storage and disposal system for locations where a sanitation infrastructure does not exist
  • Addresses sanitation compliance, health and personal dignity
  • Sanitary storage for solid waste for four people for approximately 7 – 10 days
  • The toilet is removed from its dock - manually augered into the soil where it evacuates its contents, mixes the waste with soil and buries it in the ground for decomposition

dignity toilet specifications
Roto-molded poly-propylene is low cost, structural and very durable

Molded in seal ensures sanitary, air tight storage

Carry strap is comfortable and makes transport easy

Molded in grips for augering

Two way thread ejects plug, scrapes threads and mixes soil into the waste

Mulching agitator mixes soil with waste for quick break down

aquaduct
Aquaduct
  • Aquaduct designed by IDEO - Innovate or Die contest hosted by Google and Specialized
  • Aimed at helping people in the developing world who have to make long journeys to collect water, which is often unsafe to drink
  • Large water tank mounted over the rear axles. Pedalling draws water through a filter to a second, removable, tank mounted in front of the handlebars
  • Rider pedals - a pump attached to the pedal crank draws water from a large tank, through a carbon filter, to a smaller clean tank.
  • A clutch engages and disengages the drive belt from the pedal crank, enabling the rider to filter the water while traveling or while stationary.

  • This could be modified by decoupling the 2 functions
  • Stationary pedalling – filters water

ceramic water purifier
Potters for Peace has been assisting in the production worldwide of a low-tech, low-cost, colloidal silver-enhanced ceramic water purifier

Field experience - eliminates approximately 99.88% of most water born disease agents

11” wide by 10” deep - mix of local terra-cotta clay and sawdust or other combustible, such as rice husks.

Press - hand-operated hydraulic truck jack and two-piece aluminum mold. Combustible ingredient burns out in the firing leaving a network of fine pores

Ceramic Water Purifier
  • After firing the filter is coated with colloidal silver. This combination of fine pore size, and the bactericidal properties of colloidal silver produce an effective filter
  • For use the fired, treated filter element is placed in a five gallon plastic or ceramic receptacle with a lid and faucet.
  • Basic shop with three or four workers can produce about fifty filters a day

solar bottle
Winner of a 2007 INDEX award

Uses simple solar technology to purify dirty drinking water and prevent water-born diseases

Principle is SODIS (Solar Water Disinfection) process - works with the sun to allow UV-A radiation and increased temperature to destroy pathogenic microorganisms in drinking water

The slim PET container holds 4 liters of water

UV-A exposure and thermal gain are maximized with a bi-color blown injection molding that creates both a transparent side and a dark, heat-absorbing side

lifestraw
Vestergaard Frandsen – private company in public health

Outer shell made of high impact polystyrene

Effective against waterborne bacteria and viruses

Halogenated resin elutes active halogen into influent water for inactivation of bacteria

Strong base anion exchange resin adsorbs negatively-charged halogen residuals

Granular activated carbon (silver-impregnated) adsorbs residual active halogen

Minimum 700 litres or 1 year

LifeStraw

lifestraw1
Testing - reduces bacteria such as E. faecalis and E. coli by at least 99.9999% and viruses by about 99.8%

Highly efficacious performance to meet US EPA and NSF International requirements for bacteria reduction.

The magnitude of virus reduction would appreciably reduce human exposure to waterborne viruses by 99%

Safety

Residual silver levels: below WHO guideline value and the US EPA MCL of 100 ppb

Residual iodine levels: non-existent/ within WHO limits

incubator for the developing world
4 million infants per year die in the developing world, in part because of the lack and reliability of pediatric incubator.

Design that Matters -develops products for developing countries

Incubator using parts from Toyota trucks

Car parts-cheap and easy to find in developing countries

Car headlights provide heat

AC fan moves warmed air around the chamber

Motorcycle battery for backup power

permanet
PermaNet
  • Vestergaard Frandsen – private company in public health
  • Malaria affects huge percentage of population in the tropical countries
  • Ready-to-use mosquito bed net - impregnated with an odourless and biodegradable insecticide called deltamethrin that is mixed in a resin, coating the netting fibres
  • A progressive release of insecticide from the resin guarantees retention of the net's efficacy even after 20 washes
  • This bed net requires no re-treatment or dipping and a dirt repellent feature has been added to keep it clean longer.
  • PermaNet has a WHOPES (World Health Organization Pesticide Evaluation Scheme) recommendation, which declares it safe and effective for the prevention and control of malaria and other vector-borne diseases.

using solar energy to prevent malaria
Using solar energy to prevent malaria
  • InnoCentive, Inc., SunNight Solar- funding from Rockfeller foundation
  • Concept - Leverage the power of the sun to prevent malaria
  • Comprises a small, cone-shaped mosquito trap that incorporates inexpensive paraffin wax and human sweat as the main ingredients
  • During the day a container of wax absorbs solar energy as it melts -- eliminating the need for costly photvoltaic cells and storage batteries -- and then is brought into the house at night where the heat is released at approximately the temperature of the human body as the wax re-solidifies.
  • Combined with a water based attractant derived from human sweat collected from a simple wrist band, the ingenious trap mimics the scent, moisture, and temperature profile of a sleeping body, attracting mosquitoes to the cone where they are trapped and can be easily disposed of.
  • Pilot production in February 09 – to market in May 09

cellscope
In rural areas and developing countries, clinics often lack the equipment - for up-close evaluations of malarial parasites, blood diseases and skin conditions.

The Cellscope is a 5x to 60x microscope attachment for camera phones that can be used for magnification and transmits the images to experts for diagnosis.

Successfully tested in the Democratic Republic of the Congo in August

Could soon be used by cancer patients in the U.S. to take white-blood-cell counts at home
