The pedley wheel - a water wheel driven electricity generator

摘要

This paper covers the development of a water driven electricity generator by a small UK charity. Engineering problems and solutions are exemplified by reference to two working prototypes, one in the UK and the second int he Third World, and the beneficial characteristics of a water wheel as a prime mover are established. Site requirements and potential power output are identified, again with practical references. The efficiency of the components and of the whole system is briefly analysed. A description of construction and installation, with reference to both civil works and engineering components, stresses simplicity and appropriateness for "local" involvement. Comments on capital costs and maintenance allow comparison with other forms of hydropower. It is suggested that this simple form of technology is particularly appropriate for non-technical individuals and communities to relate to. Thus construction, power management and maintenance requirements are made easier. As a tool to help combat environmental pollution and to improve living standards in the Third World, this system seeks recognition.
