Report on the wind-powered in-service training

7/26/82 to 8/5/82 - CONACOTO, ECUADOR

PARTICIPANTS

21 Peace Corps Volunteers

Ing. Eernan Alvarez S. Ecuadorian counterpart

Napoleon Cevallos, Peace Corps Ecuador

Willis Eshenbach and Paul Jankura, Trainers

OVERALL OBJECTIVES OF THE TRAINING

To learn how to design and build two types of low cost, dependable mills and pumps.

To learn about working in design groups and construction groups.

To build and test the systems.

To learn about siting of wind powered systems.

To learn about community and large-scale wind systems.

MAJOR COMPONENTS OF THE WORKSHOP

Introduction and objectives - clarifying the objectives of the program, general introduction.

Drawing - to introduce the different types of drawings used to represent designs and hardware and to practice schematic drawing.

History of windmills - done with an eye toward selecting locally useful types of wind systems.

Shop safety and tool care - so that everyone makes it through the workshop with all their fingers and chisels intact.

Joinery and strength of materials - fastening with local fasteners and materials; testing for strength.

Bearings and shafts - how power is transmitted; cranks and wristpins.

Design - how to design, what to consider, the mechanics of the design process.

Designing - designing a windmill, including the driving of the water pump.

Design presentation - presenting the designs, using visual aids, to the rest of the group.

Construction - of the mills and the pumps.

Siting - all of the factors affecting the site of the mill.

Large projects - the community and other factors involved in scaling up the size of the wind system.

Maintenance - the prevention and care of aging in windmills and pumps.

Water and numbers - the tables and calculations needed to size systems.

Testing - testing the strength and efficiency of the systems that we have built.

Presentation of projects - presentation of the projects, with an explanation of their use, to the rest of the group and anyone else interested.

Field trip- to see a local windmill.

Clean-up and close down - disassembly of the projects, cleanup the site, say goodbye.

RECOMMENDATIONS

The training was well received, and everyone expressed satisfaction with the results. Both the pumps and the mills worked as designed, with efficiencies in the ranges expected.

For model making, we used a combination of 2 Tinkertoy sets with one Erector set. These worked extremely well; people were able to use the models to actually see how the parts of wind pumping systems work together.

All of the work was done with hand tools and using locally purchased materials and tools. The material for the two mills cost around $40 and $55; the material for the pumps, $18 and $10. These figures include paint and thinner, but do not include tools or labor. The participants and trainers made the following suggestions for possible alterations in the next training.

RESOURCES

Is it possible to buy a small library to be left in the country?

A small, miniature, working model of a windmill would help explain some of the concepts.

A technical appendix to the manual containing the theoretical formulas would be useful.

FURTHER EXPLANATIONS

More relative comparisons of types of mills

Other uses of windmills

Cleanout and capping of wells

Amount of water needed to grow various crops

Applications and system setup

PARTICIPANTS

If participants are Peace Corps Volunteers, they should not be new to the country.

SCHEDULING CHANGES SUGGESTED

More time for basic carpentry skills.

Use basic carpentry skills time to build models of other types of windmills and pumps.

If possible, involve a local craftsman.

Spend more time discussing group dynamics.

Ask a few people each day to stand up in front of the group and give a short talk, in the local language, about some phase of the training.

Don't split the groups up to build windmills and pumps simultaneously - do them consecutively.

Visit a local windmill as early in the training as possible.
