Excerpts from the book New Inventions in "Low-Cost Solar Heating -- 100 Daring Schemes Tried and Untried" by Dr. William Shurcliff.
Thanks to Dr. Shurcliff for making the excerpts available.
This book clearly describes more than a hundred creative concepts for solar space heating. Although the book was published in 1979, most of the schemes are timely and worthy of thought and experimentation. It's a great way to get your mind "cooking" on new projects.
To view a concept click on its description in the Table Of Contents below. If nothing happens, I haven't had time to scan it yet. So far, most of parts 1, 2, 3 and 4 are done.
