Using an Alternator in Renewable Energy Projects http://alumni.media.mit.edu/~nathan/nep ... nator.html

MIT Nepali in Summer, 2000
During the summer of 2000, we attempted to hook an alternator up to a Nepali water mill (ghatta) to recharge batteries. A lot of our time on this project was spent working with alternators. We hope to pass on what we learned to others who may similarly not have a strong background in automotive mechanics.
Topics Covered in How To:
A Rough Outline of How an Alternator Works
How to Connect an Alternator to the Battery
Suggestions for the Would-be Alternator User
Safety Issues
Review, Drawing of Setup
Connections
Important Notes

Site Index:
Water mill technology has existed in the Himalayan region for centuries. Called a ghatta in Nepal and a gharat in India, these mills are used to grind corn, wheat, and other grains for the local agricultural community.
The aim of this study is to engineer a way to harness the rotational energy of the traditional mill and transform a ghatta into a community battery charging station. Such a renewable energy source has the potential to bring electrical lighting to the many parts of the Himalayas that remain unelectrified.
Mission Statement
Water Mills in Nepal
Design Criteria
Design Process
-- Pipes and Nails
-- A Ghatta Powered Light
-- Belts and DC Motors
-- Alternator Antics
-- Charging a Car Battery
-- System Improvements
Final Conclusions
Resources and Supplies in Nepal
