Build your own water filter!

This looks like one of those kind of projects anybody can do, meaning none other than moi.

As an addition to this idea presented here on video, I'd look into running the filtered water through a swamp cooler, which would evaporate it.  This would take place in an enclosed area, which means the evaporated water would go into the air in that enclosure.  To retrieve the water, take a water condenser and then make pure clean water out of the evaporated and filtered greywater.  Is that a plan, or not?





Update:

This was covered already in my off-the-grid series.  You can use a Review of the LIFESAVER® Jerrycan 10000 Water Filter System.  The inventor gave a TED talk here.

I'd still like to run it through a swamp cooler though.  Gets rid of salts.
