This illustrated book discusses different solar powered stills for the purpose of distilling alcohol.

The designs range from simple to complex and small to large.

The general principal of a solar still is to distill liquid by harnessing the suns heat. This arrangement is done in such a way that sizable amounts of raw alcohol mash can be distilled purely by the suns rays to produce a quality drinking alcohol.

There is enough information and diagrams in this publication for one to be able to aquire a sound understanding of the basic principals to enable them to build their own.
