Long-term Goal

• The goal is to bring the pulser pump into use
  around the world and to develop it so that it can
  reach its full potential

3
Customer Wishes

• The customers will be a mixture of farmers, small
  villagers and small businesses around the world.
• Pulser pumps require flowing water to work.
  Recomended minimum of half meter of head and 600
  liters per minute of flow per minute would be a
  guideline but it depends on the site and
  rewquirements of the user.

4
Filling the Users Needs

• Pulser pump attributes
• Easy to construct.
• Reliable
• Can be made from local materials.
• Simple to use
• Cannot be subverted to power wasteful consumer
  things like tv.
• Local power for local use. Helps slow down the
  drift to big cities.

5
Cost Analysis

• The financial advantage for villagers with strong
  backs and no money is a masive one. It is a first
  step towards using their waterpower which was
  unavailable before.
• Quality and price of competition devices
  initially seems far greater. With
  Hydroelectricity, for instance, the water power
  is converted more efficiently to electricity BUT
  initial cost is often prohibitive, and a
  relatively massive support system is needed.

6
Strengths and Advantages

• There are no moving parts. This means greater
  reliability.
• The river is efficiently oxygenated.
• Local production for local use
• Enables very poor communitys.
• The skills needed to make and operate a pulser
  pump are not so high as to make an elete group
  who will migrate to greater opportunity and leave
  the villagers helpless
• Not easy to waste the power on tv etc.

7
Next Steps of Action

• A videoclip or realtime webcam of a working
  pulser pump is desperately needed. Only then,
  will people believe in the concept of the pump.
• A few people or groups around the world need to
  make pulser pumps and communicate with each other
  or with me to develop it further
• The pumping with foam balls option needs to be
  develloped.

8
Institutonal science

• I have been in contact with scientists who
  believe that this device is worthy of research.
• Funding is the difficulty.
• There are no bells and whistles.
• Consiquently it is not EXCITING enough.
• One man said that the administrators would
  happily spend thousands on the latest high tech
  teaching aid BUT would find difficulty funding
  the repair of a broken shelf

9
Applications

• Pump water
• Wash sand for building
• Pump air for sewage aeration
  fish tank aeration
• Producing partial vacuum
• Washer drier

10
Simplicity is a virtue!

• The pulser pump is really simple and can consist
  of a few pipes in a hole dug in the ground
• The design can be changed to suit local
  conditions, skills and materials

11
Pulser parts Part 1 The Tromp

• The pulser pump is half tromp (in red)
• Tromps were used in the last century to provide
  compressed air for
• Mine ventilation and machines
• Tunnel building
• Air powered electricity generators

12
Part 2 The Airlift Pump

• (Part in red)
• Airlift pumps are used to pump hasardous
  materials, water from very deep wells, and
  archeological artifacts from the ocean floor to
  the surface.

13
More on airlift pumps

• Airlift pumps are generally powered by a high
  compresion air compressor.Pulser pumps are
  powered by a Low compression tromp.
• This means that a different type of flow occurs.
  Slug or plug flow

14
Easy to lay pipes from a to b

• It is not necessary to pump straight up to a
  header tank.
• As long as the down pipe is vertical the the pump
  will work. The pipe to the user can meander
  along the ground or go straight Up

15
Improvements possible

• Pulser pumps are at an early stage of
  development.
• The moving diagram here illustrates how the
  efficiency can be improved by using balls as
  pistons

16
The end of the beginning!

• I have been advocating pulser pumps since the
  late 80's. Since then they have appeared in
  print, on cd rom and people round the world have
  seen the webpages.
• I have recently been told that testing has
  started in Kenya.
• You can help my effort by joining the pulser pump
  yahoo group, making a model, making a pump,
  webcamming a pulser pump or just publizing the
  pump.
• If you start now, you might even go into the tech
  history books! Brian White feb 2002
