INTRODUCTION 1999

This work was done 1976, but there is a good chance that very few people read it - such was the nature of media in those days and the problems and costs of promulgation. So now it is 1999 and we have internet web and email - so here it is in a form which costs nothing.

Thanks to Katule and to all at University of Dar es Salaam, Morogoro, Tanzania, especially those of us who put up with the screeching sound of bearings running throughout the day for weeks on end.

The results below are interesting and useful, and are pretty hard to get any other way.

Unfortunately many economies in the world have remained stagnant or even gone backwards over the last 20 years, so a lot of this kind of technology is still 100% valid, if people can even afford these low-cost techniques...

Sorry for the lack of pictures and diagrams on this report....

Thanks to VITA and ITDG and other organisations who help to disseminate reports on this kind of stuff.
