TheLemonBottle.org is an open-source and collaborative design project which aims to combine three proven technologies:
- SORAS — Solar oxidation and removal of arsenic
- Potters for Peace ceramic water purifier, and/or
- SODIS — solar water disinfection
This is meant to supplement a community or home arsenic filtration system (W: $USD 40). The cost of the LemonBottle should be negligible.
