DIY Saltwater Survival Bottle (Compact Desalination Kit)

[ad_1]

DIY Saltwater Survival Bottle (Compact Desalination Kit)Any water we harvest in the wild ought to be purified. But what do we do when the only water offered is saltwater? In this video, NightHawkInLight explains how to make a DIY saltwater survival bottle.

This transportable desalination kit will make quick operate of converting saltwater to freshwater by capturing steam. The steam is concentrated via cooled, copper coils and the outcome is pure, distilled water. Here’s how to make it…

Gear

  • 1 stainless steel, non-insulated water bottle with metal cap
  • four feet of versatile ¼” copper tubing
  • Correct angle brass compression fitting with ¼“ openings
  • Plumbing solder (lead cost-free)
  • Soldering flux/paste
  • Fine grit sandpaper
  • Butane torch for soldering
  • Drill
  • 1/4” drill bit
  • 1/16” drill bit
  • Pipe cutter

Directions:

  1. Take away the metal cap and any rubber or plastic gasket on the cap
  2. Drill a ¼” hole via the prime of the cap
  3. Drill a second hole with the 1/16” bit amongst the hole in the prime and the rim to let heat escape although soldering
  4. Reduce a length of copper tubing that will emerge ½” from the prime and bottom of the cap
  5. Reduce two tiny pieces of solder and wrap them about the tubing on the prime and bottom of the lid
  6. Coat the solder with flux and melt to solder to develop a weld
  7. Solder and seal the 1/16” hole
  8. Reattach the gasket right after the cap has cooled and screw the cap back on the bottle
  9. Attach the appropriate-angle brass compression fitting to the tube at the prime of the cap
  10. You can insert a rubber gasket into the fitting to develop a watertight seal to use the bottle as a traditional water bottle
  11. Take the copper tubing and wrap it tightly about the bottle eight or 9 occasions
  12. Bend the prime of the tubing up along the bottle and the other finish down along the sides of the bottle
  13. Take away the coiled tubing and attach a single finish to the brass fitting and tighten
  14. Take away the rubber cease gasket from the brass fitting if installed
  15. Fill the water bottle with saltwater and suspend the bottle of more than an open fire or a fire contained in a can or hobo stove
  16. Set a container at the other finish of the tubing protruding away from the water bottle
  17. As the water starts to steam it will condense in the tubing and start to drip fresh water into your container
  18. To greater condense the water, immerse half of the coiled tubing in a pan or can of cold water so the bottom is surrounded by water or wrap the coils with a constantly wet rag
  19. Cease the method ahead of the bottle is empty so you do not concentrate salt and minerals on the side
  20. Add a splash of the saltwater to the distilled drinking water to deliver electrolytes
  21. You can also use a solar reflector oven to heat the bottle but paint the bottle black
