AT-HOME DESALINIZATION TECHNIQUES by Kent Gruetzmacher
While regular droughts and fresh water shortages are becoming a reality for many , seawater is still a plentiful resource . Though desalinization is typically seen as an expensive option , Kent Gruetzmacher says there are some basic home techniques that can be used .
While Earth is rightly dubbed
“ the blue planet ” thanks to its vast oceans , this terminology falsely alludes to a supply of abundant , consumable water . In truth , only 2.5 per cent of the Earth ’ s water is fresh ; that is , consumable by both humans and typical plant species . Moreover , a majority of this fresh water is contained in snow and ice — leaving only 0.3 per cent of Earth ’ s water available to be utilized .
Through the past decade , as vast areas of the planet experienced water shortages , the global populace has recognized the need to for novel water sources . The most blatant option is the ocean ; however , our vast reserves of seawater cannot be utilized for human consumption or crop irrigation without extensive desalinization treatment . Traditionally , the desalinizing of seawater as a source for drinking water has been viewed as unpractical . This is largely because , on a molecular level , the water and salt bonds within seawater are notoriously strong . As a result , the desalinization process requires a huge amount of energy — meaning that it is a very costly enterprise , both environmentally and financially . Still , for inquisitive homesteaders looking to desalinate water for drinking and irrigation , there are a couple of options .

Through the past decade, as vast
areas of the planet experienced
water shortages, the global populace
has recognized the need to for novel
water sources. The most blatant
option is the ocean; however, our
vast reserves of seawater cannot
be utilized for human consumption
or crop irrigation without extensive
desalinization treatment.
Traditionally, the desalinizing
of seawater as a source for
drinking water has been viewed
as unpractical. This is largely
because, on a molecular level,
the water and salt bonds within
seawater are notoriously strong. As
