    DIY Solar still

    So, I finished hammering together a solar still in my garage and took it outside for a test run in the sun. Hoping that it will distill enough water to keep my still miniscule collection of CPs alive and happy...
    I fill it up with regular tap water through a small opening in the back. The inside is coated with black silicone, keeping it waterproof and allowing it to withstand the heat necessary to evaporate the water. The sun evaporates the water, which then condenses on the glass panel and runs into a PVC pipe at the front, which in turn drains through some plastic tubing into an empty bottle.
    Pretty cool, huh? Has anybody else ever tried this?

    very cool! looks like should work well..
    One thing I read awhile back..if you put some gravel in the main bin, it provides more surface area for the tap water
    to evaporate off of, getting you a higher collection rate..(if you need that..which you might not..)

    Very interesting! Seems like it could have some algal problems due to the combination of light and water. Please keep us updated on how well it works. I might need to make one!

    Today I got about 1 quart (for those metrically inclined: about a liter) of distilled water. I haven't really fine tuned it yet. I would need to seal up some of the openings around the PVC pipe and fix the sheet of glass more firmly to the base. So far no leakage problems, which means the silicone is making a nice seal inside.
    Hadn't thought of the algae, but good point--I will keep a lookout for that.

    Algae is one thing you don't want in your plants' water, especially if it gets light. The stuff can ruin huge amounts of water in a really short period of time. It's good that you're keeping an eye out for it.

    Just a quick suggestion: Do you have a dehumidifier? The water from that should work. They are, essentially, distillers; they capture water vapor from the air and condense it.

    If the temperature inside the contraption gets hot enough, algae might not be a big issue.

    Unfortunately, you then run into the issue of fungi/molds. Dehumidifiers also pull in spores and dust particles which can result in a fungi infested "soup". I suspect that the distillery might be the wiser way to go.
