Have you ever considered hydro-electric power? Arthur Williams presents a practical solution in this little book on using electric water pumps in reverse as generators of electricity for "micro-hydro" applications. Mr. Williams has extensive experience and knowledge of how to adapt readily available, inexpensive water pumps into little generators.

Excerpt from a forward by Dr. Nigel Smith of Sustainable Controlled Systems LTD. Nottingham, UK:

"whilst it is much easier to purchase a pump than to manufacture a turbine, there are a number of important requirements that must be followed in order to select a machine that will be reliable and operate efficiently. This guide goes through the process step by step, with worked examples and case studies and draws upon the author's extensive experience."
