This book is very technical. It is full of charts of the sunﾒs path and other scientific solar data. Chapter 4 provides instructions for building your own solar food dryer. It is very complicated. A neighbor is building mine and has complained a lot about the difficulty of the task and especially following the bookﾒs directions. This man built his own house. I only recommend this book for someone with some scientific knowledge and/or good woodworking skills.
