Session 2 History of wind systems

TOTAL TIME: 1 Hour

OBJECTIVES: To look at and discuss wind systems used throughout history; with an eye toward selecting types and styles which might be useful locally.

MATERIALS: Blackboard or equivalent, 35 MM Slide Projector Screen, or Photographs and Drawings

PROCEDURES:

Step 1: 15 minutes

Discuss the history of the development of wind systems, emphasizing water-pumping applications.

Step 2: 15 minutes

Examine the wind systems pictured in the handouts, noting the different construction methods used.

Step 3: 15 minutes

Discuss the various types of wind systems by categorizing them when possible.

Step 4: 15 minutes

Examine the windmills pictured in the text and discuss the possible uses and ease of construction of the various types.

Trainer Note

Many of the construction styles and other details of methods in this text are very appropriate to low resource areas.

RESOURCES: Text - Homemade Windmills of Nebraska
