Aero the water bottle that pulls moisture out of the air

Anyone hear about it? Runs on solar and it appears it may be on the market soon. They say could fill a 20 oz bottle it looks like in a hour in a humid climate.

This self-filling water bottle is the ultimate in vaporware

Anyone Tried This invention ?

Fontus water maker?

Innovative new kind of water maker - water from air

I want a couple when it's available.

Darn, I just bought a watermaker!

Re: Aero the water bottle that pulls moisture out of the air

So essentially a dehumidifier? A while back I wondered about using water from my home dehumidifier for drinking, giving to pets, replenishing fish tank water, and gardening... A bit of Google searching reveals lots of articles on the topic, like this one:

Ask Umbra: Can I reuse the water from my dehumidifier? | Grist

Simple answer is, no, we shouldn't drink water from our dehumidifiers. Several reasons are given... all of which would be challenges the makers of this device would need to overcome. Not saying they can't do it... just that those things will have to be taken into consideration.

And, hey, if it works, great! I'd love to dehumidify the interior of my boat while generating drinking water

I don't see where any of the risks in that article are relevant to the waterbottle. (It's not the water that's the problem, it is the way it is collected: metals leaching from the coils and contamination in the run-off collector. Personally I find the first concern very dubious).

The biggie is that it is only capable of producing survival level quantities of water.

Re: Aero the water bottle that pulls moisture out of the air

I have a small peltier effect dehumidifier on my boat. The water that comes out of it looks pretty clean. I'd prefer to filter it before I drank it but if it was my only source of fresh water, sure I'd drink it.

I don't know how much it produces because I've rigged it to drain continuously into the sink. I doubt it's half a liter per hour.

That Peltier Effect is pretty interesting. Did you know you can reverse it and generate electricity directly from heat with no moving parts? It's not very efficient but it does work.

Hi I found this on web after simple search: "Self-filling" biking bottle pulls water out of thin air : TreeHugger

It would be useful on our yachts when customized for that purpose. I can imagine such a system producing more than the 1/2 liter per hour which it does with the bike design.

I about agree with you. The metal contaminates sounds like an non issue if stainless were used in place of cooper soldered tubing If made such that you could get at the guts for periotic PM should address the concern about microbes. Or possibly pumping the water through a microbial filter and/or passing the air through an ionizer. I wonder if it isn't the lack of market in the developed countries which would be the target market that could afford it.

Re: Aero the water bottle that pulls moisture out of the air

Condensing water out of the air is quite doable (In humid climates) and with proper design its safe enough. But.... The energy required to condense that water is quite high for the quantity of water produced. Also if the air is not filtered (that proper design thingy), dust and other "stuff" will be trapped in the water as it condenses.

For the fellow with the water maker, Water Makers still gives the best performance and lower overall energy usage, by quite a bit.

I'm waiting for graphene water filters which should drop the cost of filtering fresh water from sea water by an order of magnitude or so.

For Hopcar: Nasa used a plutonium thermo-pile to make heat that is converted to electricity via Peltier Effect/thermocouple. The Delta T of 800 degrees made it work well. A bit pricey and low overall efficiency, but no moving parts.

I heck! They won't sell me plutonium at Lowes I will try Ace Hardware.

Re: Aero the water bottle that pulls moisture out of the air

Sailorchic, They learned that trick from my Junior High Science Fair Project.
I used some copper wire, some iron wire and a Bunsen Burner to make a flashlight bulb glow. They just substituted Plutonium for my Bunsen burner!


Given the number of rockets that explode in the atmosphere, I wonder if it's really smart to be launching Plutonium?


I looked up my dehumidifier that is about the size of a loaf of bread. It is rated at about 8 oz. per day. That's enough to drop the humidity in my little cabin from about 80% to just over 60%. I have my doubts about a solar powered bicycle water bottle making 1/2 liter per hour. If it does, it would be a great thing to have in a life raft.

My thought exactly on the quantity and the life raft. If it made 1/2 liter pre day, that would be a life saver.

the article about the bicycle bottle didn't mention any energy source at all. it sounded like it was zero human produced energy to give you a half liter of water in an hour.
