Originally published early 1900's. The illustrated contents contain detailed chapters and plans for building small windmills: Windmill Evolution - A Working Model - Designs for Building a six foot and a ten foot working windmill - Electricity production by wind power.- Design and Output etc. Many of the earliest hobby and craft books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing many of these classic works in affordable, high quality, modern editions, using the original text and artwork.
