For years, the energy from water power turned the wheels of our industries, lighted and sometimes heated our homes.That energy could do it again today, says author Dermot McGuigan. There are myriad small streams that could provide home-use power to many thousands who could build their own small generating systems. Already some of these have been harnessed again.Do you live near a stream? Read this book and learn how much power you could provide in your own backyard.Dermot McGuigan tells you: **How to assess the potential power at your site. **What the payback would be. **Which of the many systems may be suited to your site.You will understand the many methods of generating power: the time-tested overshot wheel, and the more efficient Pelton impulse wheel, Turgo impulse wheel, cross-flow turbine, Francis and propeller turbines.Here"s a method of assuring yourself of a good source of cheap power. The initial cost may be high, says McGuigan, but maintenance costs are low, and the payback can be rapid, and followed by years of free electric power.
