The Solar Thermal Energy auto run CD  at my store is the same one I use to teach solar thermal energy workshops at Farmingdale University. This CD also contains a permanent edition of SunEarth. While supplies last a 98 page STE companion book designed to facilitate the learning experience will be included at no extra charge.  Shipping is free in the United States, Canada and most other locations on our planet. If you are seriously interested in  Solar Thermal Energy  this slide show/ book combination is a must.
Another great book available from my store is Energy Independent Housing
