DIY Solar Water Distiller! - Simple Solar Water Distilling - Easy DIY (for Survival/SHTF)




About: hi there. on this instructable channel i'll be covering all types of DIY solar power projects (as well as off-grid/survival/green living projects) that are easy to make out of readily available products and ...

in this instructable i show how to make a simple solar water distiller just using bottles.

Step 1: Watch the Instructional Video...

Step 2: Read the Description...

DIY Solar Water Distilling! Simple Solar Water Distiller! Easy DIY. Great for survival/SHTF situations. made using 2 clear (plastic or glass) bottles and glue (or tape). fill one bottle with dirty/or saltwater. then connect the second bottle and set in the sun. within a few minutes the water begins to evaporate and the other bottle collects the clean distilled water vapor. tips: make sure the bottles have an airtight connection. prop up bottles at a slight angle so as the dirty/or saltwater starts to evaporate - the max. amount of water vapor will travel up to the higher collection container. works best in bright sun.

Step 3: First: Gather the Items...

1.) 2 clear plastic or glass bottles

2.) glue (or tape)

Step 4: Drill a Hole in Each Cap...

start by drilling a hole in each cap. i used a 1" hole saw to drill the lids

Step 5: Then Glue the Lids Together

i used super glue (but you can use tape)

Step 6: Now Add the Dirty or Saltwater

finally, add the dirty or salty water you want to clean, screw the lids on, and prop it up at an angle in the sun

Step 7: Here Are Some Close Ups...

after a few minutes, water droplets will form in the collection container. that's clean fresh distilled water!

Step 8: Have Fun Building and Using It!

    Hmm. Survival? So I'm unlikely to have access to a drill and superglue. We need an option to do this from found bottles (maybe washed up on a beach) and a way to attach the bottles together using rudimentary tools. Anyone got suggestions?

    hi there. one possible way to cut a hole in the lid (assuming it is plastic) could be to use a heated knife. if you had a small pocket knife you could heat the blade in a fire and that could allow you to cut the hole in the lid. as far as connecting the two lids... maybe use some kind of sticky tree sap to temporarily connect the lids to one another? or there might be a way to melt the lids together?

    ok i have to ask, does it work with piss?

    if you put a small hole in the bottom of the top bottle will it drain into a cup?

    Driling a hole in the lower part of the higher bottle can make the water flow directly in another one.... But i'm asking :will it have impact in the vapor process too ? (adding cooler air will make the system faster.... But how many vapor May flow by this hole ?)

    why not use a straw in the middle? works in the chemistry lab

    could take it a step further . have it hinging in the middle . so when
    the clean water starts to fill up , the weight will slowly pull it down
    and youll know its done when the bottle has fully tilted . you would
    need to test to see the amount needed so when it tilts the dirty water
    does not flow over . you could put little flags on the bottle so you
    know when its done .
