Solar Still
From Open Source Ecology
Basics
- Typically refers to a direct, passive, solar thermal water distiller
- Can be as simple as a plastic sheet, collection cup, and input basin, or very complex
- PILE of research to sift through on this subject
- These are also different from grid scale Solar Desalination Plants, which use similar methods to fuel based systems (multi-phase flash distillation), but with solar thermal power
Geometries
Add-ons
- Fins (additional heated area below water surface)
- Pre-Heating of water (often via Parabolic Trough , or Thermosiphon
- Use of Heat Exhchangers (for cooling the air to condense vapor using the input water)
- Contactor Based Evaporation
- Evaporation Pond for disposal of brine, and production of salt
- ... (need to complete this, and sift through more papers)
