Human powered water transport
Positioning this technology in the
Functionality Grid
Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief deals with the phenomenon of human powered water transportation. More particularly it deals with the use of a rolling drum drawn by a person. In terms of the Atlas of Technological Megatrends, it is concerned with the functionality of matter transportation.
In developing societies providing water is usually a major problem. The task of fetching water is mostly the responsibility of women or youngsters. Frequently they have to walk long distances to water sources.
Three kinds of devices are used to carry water:
  • Buckets or cans carried by hand or on the head
  • Back packs made of metal or plastic
  • Drums that are rolled ahead by hand
Now a variation of the rolling drum has become available. A drum that is pulled. Called the Q Drum, it is shaped like an elongated doughnut, with a gap at its core to allow a loose "axle" to pass through. The axle can be made of flexible material like rope. The ends of the rope are then brought together in front of the drum and either held by hand or fastened around a person. The person provides the energy to pull the drum. The drum is made of polyethylene, can hold 50 liters of water, has a length of 475 mm. and is 430 mm. in diameter.
This technology is at an advanced stage of development and dissipation. In terms of the NASA scale of Technology Readiness Level (1 to 9), it is between levels 7 and 8.
The technology has been featured in a number of publications and television programs, and is on display at various design centres in Europe and Asia. Further applications are foreseen in the military, in agriculture, and in disaster relief operations.
