Sunshine to Dollars Is a book you can buy (I bout it in PDF). The author tells how you can get and make free solar products, green house, ect. I was interested on the part of receiving FREE solar panels and glass for green houses (I would like to have a green house soon).

It cost 12.95, and the PDF is about 75 pages w/pic. and step by step on how to make things like; water heater, converts salt water to fresh water, ect. (just click on the link for more info). 

The author also has other books about cars w/no gas and other ways to save money by harnessing the sun.

I’m still working on implementing the authors ideas.
