Water From Thin Air! (I want one)

Technology : Water Filtration Systems : Reverse Osmosis Water | EcoloBlue™ Life & Energy

Seems like a cool idea. Might use a bit of power (280watts) but for those with a genset, it might be a watermaker as well.

Reading the instructions now. Just came across this:

"Do not tilt the unit more than 20°; if it is tipped greater than 20°, unit must
stand undisturbed for 24 hours BEFORE it is operated."

Now that's not going to work! I wonder if the technology could be used in a simpler more boat-friendly design.

There is a lot of water in the air. I collect about five gallons a day just running the air conditioner in the house at 80 degrees.

A quick look at the specs indicates that it needs about 0.5 kwh/liter. An RO unit needs a small fraction of that (~ 0.03 kwh/liter for at least one model).

This sounds just like the dehumidifier I use at home. I use the water that comes off the dehumidifier for my batteries. It is crystal clear and to all intents and purposes, distilled.

My thoughts on this is that if I need RO to clean up the water then why not use salt water in a normal watermaker?

I've read about them before, it does seem like a good idea. Only real issue I see is the power draw, and that it has to be an area that already has some water to produce the humidity.

Think that someone who has a dehumidifier aboard already has most of the equipment to make one, just need a filter for the dust and container for the condensate.

Don't feel that all the sterilization steps are really needed, as it is coming directly from the air you're breathing at the time, so if something's in the air you've already ingested it.

From the experience of having dehumidifiers in my home, even a high-powered mains-driven unit that runs all day only produces about 8 or 9 liters of water in 24 hours. And then the RO component still has to "purify" it.

I don't believe my house bank will like that.
