Title: DESIGN FOR PEOPLE IN NEED


1
DESIGN FOR PEOPLE IN NEED
  • Suresh K

2
Agenda
  • Issues concerning developing countries and
    corresponding low-cost solutions
  • Sanitation
  • Water
  • Health

3
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

4
BioLet's Composting Toilet
  • Seen more as a green product places where there
    is severe shortage of water

Dignity Toilet
6
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

7
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 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.

10
Aquaduct (contd)
  • This could be modified by decoupling the 2
    functions
  • Stationary pedalling filters water

11
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
  • 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

12
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

13
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

14
LifeStraw
  • 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

15
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

16
Incubator for the Developing world
17
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.

18
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

19
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
