I am an engineer. I was curious what kind of power that you can get from small power projects. This is an excellent book is describing what you can get from water with all the basic info on the elements: water, head, flow rate, battery, alternator, turbine. A feature of the book that I thought was very good is the rating system for how much power one needs on a scale of 1 to 6. In particular, I was interested in how much power to run a refrigerator. This book had the answer.
