How to make a portable DIY salt-water desalination kit using a single-walled stainless steel water bottle (you don’t want it to be double-walled or “insulated” for this project) some 1/4″ copper tubing, a lot of solder, a single right-angle compression fitting, and that’s about it.
In this video I show how to make a simple distillation kit from a water bottle that can be used to make fresh water from ocean water. Any steel container could work for this project.
I almost used a small stainless steel food container, but decided a water bottle was a more practical object to carry.The best part? It can be used as a normal water bottle when not being used to distill salt water.
This portable desalination kit will make short work of converting saltwater to freshwater by capturing steam. The steam is concentrated through cooled, copper coils and the result is pure, distilled water.
