Fontus is a water bottle that makes water from thin air


Never run out of water again

You're out having adventures when you run out of water miles from a source. What to do? The Fontus water bottle eliminates the problem, as it makes drinkable water out of air and light.

So how does it work? A small fan draws in air, which is then run through a special filter and pressed into the condensation chambers. Powered by solar energy, a series of small coolers makes the moisture within the air condense. The resulting water then drops into the bottle's main body and is stored.

The water is drinkable and completely safe, thanks to capsules that remineralise it.

The bottle comes in two versions. The Fontus Airo is the standard model, while the Fontus Ryde is the version made especially for bikes – it clips onto your bike frame, and has its solar panel on the top, facing the sun.

Instead of a fan, the Ryde uses the air stream you generate while cycling to suck in air.

Not only could these be useful for adventurers and those exploring the great outdoors, they could also help provide water in the developing world. The only problem is the price.

At the moment, the Fontus Airo costs $200 (£142) on an early bird, which is mighty steep for a water bottle. The Ryde starts at $165 (£117), which is a little cheaper, but not much. It's smashed its funding goal of $30,000 and still has a month to go. It'll ship in April next year.

good idea and concept initially but how long will it take to fill up the bottle?

At 20 degrees C the max water content is 17 grams per cubic metre, at 50% humidity then you could possibly extract 8grams of water per cubic metre sucked through the machine. So it'll have to go through 12.5 cubic metres of air in a quite humid environment. I think this is going to be difficult with only a fan powered by solar to do... Not convinced.

Reminds me on the stillsuits in Dune. Cool idea but probably completely impractical.

Genuinely neat idea. But...I figure it would take ages to actually fill up that water. It would probably be faster if you continuously changed locations as there's definitely not an infinite amount of water in any one space. And, obviously, it would work better in more humid environments.

I'm curious how you figured that. I was following the same line of logic but without the numbers haha.

found some stats for water in air, back of an envelope mathematics... not great but enough for be to cry foul on their claims for me anyway

Ah I was curious where you got your information. My knowledge of meteorology hardly extends beyond the basics.

From what I can tell, this product doesn't actually exist - It's some mockups combined with a crowdfunding campaign to see if the technology can be made to work (and there is a lot of discussion that there's no way it can produce any significant amount of water given the tiny solar panel)


The article is worded like it's an actual thing. Did TR check this, or just cut and paste the press releases?
