Animal Power

 

In the absence of water or wind power, animal power can also be an important source of energy. Animal power is five to ten times stronger than manpower. 

A man with 70 kg weight can carry between: 7 - 9 kg of weight easily, if working the whole day, 25-35 kg of weight for a short period or 60 – 150 kg if pulling or pushing a cart or a wheelbarrow. 

A horse can pull on average: 30 – 50 kg of weight working the whole day, 250-400 kg weight for short period, or 350-500 kg of weight on an horizontal road. 

From the above data, it is clear that putting animal power to use will not only increase work output, but will also improve the results of numerous activities that are currently poorly carried out by human labour. 

To fully utilise the potential of animal power, efficient technologies are needed, such as: 

The Persian wheel, which is used to lift water from a well, rivers or streams, 

  • Different types of animal-powered pumping systems;
  • Carts for transporting people, goods etc; 
  • Food processing machines powered by animals;
  • Universal power gear driven by animals.

Although animal power have been used for centuries in some countries, their potential have not been fully exploited in Africa.

  • Universal power gear driven by animals. 
  • Activities such as grinding and pumping could have a great impact in rural areas.

The use of animal drawn in agriculture can cut time and human labour needed by 50-80 per cent and boost the amount of cultivated land by 100 per cent.

The use of animal can significantly reduce human energy requirements in agricultural production and increase productivity.

In Islamic world and Europe, animal power succefully replaced man’s hand at the millstone to carry the tedious and exhausting task of grinding.

Animal drawn also increases water infiltration into the soil, which improves plant growth.

"Operational reliability is the forte of traditional technologies. A traditional water-raising facility can quickly be repaired by either the user himself or a local craftsman. The inability to prevent or repair a failing diesel pump can jeopardize weeks of work. Under certain circumstances, it can even threaten the livelihood - or the very existence - of those who depend on it to work" Peter Löwe "Animal Powered Systems " GTZ, 1986.
