Put the wind to work with one of these turn-of-the-century designs.
You'll learn about different types of windmills, some of them unusual. Then you'll be shown how to build a model tower windmill similar to those in Holland.
Chapter 3 will show you how to build a real power producing windmill with a three foot diameter sails. It may be a small wind motor, but it can drive a small dynamo. You get all the important design details.
In Chapter 4 you are shown how to build a 6 foot diameter windmill capable of driving a 30 watt dynamo in 16 m.p.h. wind. You'll see many detailed drawings showing how the all-wood machine is built, and how metal gearing brings the power down to ground level.
Another chapter reveals a 10 foot diameter wind motor. The last chapter gives you tips on generating electricity - high tech in 1910. Obviously better generators are available now, but the basic principles still apply, and control methods still work.
