This page needs tied in with Understanding_Solar_Stills and solar distillation in detail.

I've tried to develop a variation of the solar still over at with 2 plastic bottles and some tube between them, to be used massively in emergencies. I found my initial setup didn't work, but I think a new iteration might prove to be better.

The whole idea is "forced evaporation" (in one bottle) + "forced condensation" (in the other). I'm guessing I could dump my design and data in a page here, and let people who are better informed, or who can continue where I left off, tell us. Maybe it just can't work, or it's very easy.

Usable commercial solar stills ?[edit source]

Usable is the WaterPyramid solar still (Aqua-Aero WaterSystems BV). However there are shortcomings on 2 planes;

  • The method of solar destillation; the current waterpyramid doesn't separate the cooling (on the edge of the plastic) not from the heating (solar radiation). This reduces efficiency.
  • The use of a fan (which needs electricity) to continuously blown into the pyramid. Beyond the need for electricity, there is also the use of a PV-panel, which increases the price even further.
  • The use of plastics for the solar distillation chamber

The Dutch company Solar Water (see may have some answers. Their solar distillation system uses a PV-panel (already in the WaterPyramid) and uses this to seperate heating and cooling, increasing efficiency.

I'm also wondering whether the use of mirrors outside of a glass structure (pyramid, ...) not standing in the sun would solve this (partly ?) The water coming into the shaded pyramid using a trench. The rays are concentrated on the trench from the outside mirrors, immediatly heating the water (and little else) and having it condense at the glass pyramid; heat & cooling are then probably quite seperated.

Suggested merge[edit source]

I've suggested merging solar distillation into solar stills, as they cover the same topic and same technologies. I chose this "solar stills" as the preferred name as this is talking about stills, more than the process. Conceivably we could have a page on each and "distillation" might cover technologies that don't fit the description of "still". (Not sure, though - it's not my area.) --Chriswaterguy 09:53, 12 November 2011 (PST)

Very useful ideaThere is something similar? Thought I would comment and say great theme, did you make it yourself? Looks great![edit source]

Personally Im impressed by the quality of this. Sometimes I fav stuff like this on Redit. Although this time Im not sure if this would be best for the users. Ill take a look around your site though and submit something else.
