Trainer Notes

To help illustrate your talk in Step 3 of this session with pictures of treadle and pedal devices, refer to the resources listed above and select several of the illustrations found in them. These pictures should be distributed to the participants.

Procedures:

Step 1. (25 minutes)

Ask the participants to form small groups. Have each group discuss and record their past experiences and/or knowledge of pedal/treadle power.

Trainer Notes

Explain that each group should list on newsprint what pedal/ treadle devices they have seen and what devices they have read about.

Step 2. (30 minutes)

Reconvene the groups and have them discuss their experiences and knowledge of pedal/treadle power.

Trainer Notes

Be certain that each group posts their list of devices. Leave the lists posted. They will be referred to again in Step 4.

Step 3. (50 minutes)

Give a brief talk on the history of technology and innovation and the history of the development of pedal/treadle power as a renewable energy technology, mentioning some of its different applications along with some specific examples of successful devices.

Trainer Notes

Background material for this talk can be found on pp. 13-14 of Jequier and pp. 1-25 of McCullough. During the talk, distribute copies of the illustrations of pedal/treadle devices (found in the session resources) and briefly describe each one. A; the end of the talk, encourage questions, comments or discussion.

Step 4. (15 minutes)

Have the participants categorize the devices listed by the groups in Step 1 and the devices introduced during the talk in Step 3.

Trainer Notes

The devices can be placed into the general categories:

* Agricultural tools

* Home implements

* Shop tools

* Transportation

Post these categories on newsprint and list the devices under them.

Step 5. (10 minutes)

Conclude the session by reviewing the objectives and mentioning that participants should consider the devices listed as possible construction projects during this phase.
