BOOKS

How to Build a Solar Hot Water System is an easy to follow, step-by-step 80-page book with clarified theory and dozens of illustrations. It was written to save money, and our little blue-green planet. Are  you tired of  watching valuable resources disappear? Are you are tired of paying high prices for something that should be our birthright?  Are you searching for the possibility of change?

 

 

Energy Independent Housing is more than a set of blue prints for a solar home. Detailed plans and illustrations are presented that will enable the reader to construct the illustrated energy independent dwelling, however this book is best used as a construction guide for all kinds of energy independent  housing.

 

 

Solar Thermal Energy  is designed to be used in conjunction with the STE multimedia interactive slide show. There are over 39 questions generated from the show. The best way to learn about solar thermal energy in the shortest period of time is to view the show with this book at your side, and work out the problems as they’re presented. When you feel like taking a break or when you need time to do a calculation hit the pause button. When you’re ready to move on hit the pause button again, and the program will resume.  

 

                                               

 

COLLECTORS 

For more information about this set of  serpentine solar collectors you should contact me directly. Although they are for sale I encourage people to build their own with the help of my book How to Build a Solar Hot Water System. They are large and expensive to ship, but I will personally deliver them to any place on Long Island.

 

 

 

 

This is a picture of my wife, holding an absorber plate with backing. You are looking at it from the back.

The absorber plates are also for sale, but my wife is not. I ship them in packs of eight (enough for a set of two solar collectors like the ones above).

You are encouraged to build them yourself, but I'm willing to ship them to any place on the planet. More information about absorber plates is available from Strawberry Fields Solar Book Store
