Bicycle Bottle System Condenses Humidity From Air Into Drinkable Water
Diggester writes The weight of water limits how much can be brought on a long bike ride. There isn't always an option to stop and fill up from a clean stream or drinking fountain, but water could be obtained from a different source: the air. Austrian industrial design student Kristof Retezár has created Fontus: a prototype of a water bottle system that condenses humid air into clean, drinkable water. His design made him a finalist for the 2014 James Dyson Award.
So, a small wind turbine (or taking turns on a bike), and any hot humid area where clean drinking water can be scarce is a good fit for this.
I can see this applying to FAR more than cycling.
Interesting.

You cannot produce a maximum of 500ml/hour and 1 drop/minute. 1 drop per minute is approximately 3.9ml/hour. This sounds like a more realistic figure than 500ml.
Distilled water is just what you need to quench your thirst after a physical excercise. Apart from the health issuses... Where the F can you find air moist enough for this to work?
My car carries, like hundreds of bottles.
I don't see the problem.
On a long flat bike ride, once you get the weight going, Newton's first law keeps it going.
I remember 2 decades ago in high school they had distilled water squirty bottles to use in experiments. If you got it in your mouth it tasted rather bad. Since this is a kind of distillation shouldn't the water taste foul?
So, a mini-windtrap? Kinda cool.

"According to a description of the product on the award site, solar panels generate the electricity needed to cool the upper chamber of the device, while the bottom heats up. As the bike moves forward, air is pulled in, and then slowed and cooled as it moves through that upper chamber."

A long time since I took the survival course, but when considering being downed at sea I seem to recall taking the salt water, forming a pool of it the raft, and allowing it to condense on a slanted surface above it and drip potable water into a container. This device might work well in a warm, sunny, floating on the ocean environment where humidity and energy from the sun are plentiful.
Apparently the industrial design curriculum doesn't cover thermodynamics. Condensing water at room temperature requires shedding about 680 watt-hours of energy per liter, and thermoelectric coolers tend to burn off more than twice the energy they pump (depends on a few variables, but practical devices in practical situations usually fall in that ballpark). You'd need somewhere near a constant half-kilowatt to provide for one person's normal water consumption. Much more if they're exercising or in a hot environment.
Bugrit! Millenium hand and shrimp!
How much does the device weigh? A camelback with 1 liter is about 4 pounds / 1.8 kilos?
Plus the camelback is multipurpose and can carry snacks, tools, etc.
You can also stop and get more water. I know I know.... Crazy talk.
Do not look at laser with remaining good eye.
Where the guy was told the water bottle would gather water from the air, so he shouldn't even bother to fill it up?

You're going to need a droid that understands these vaporators. They speak a language similar to that of binary load lifters so consult your local dealers.
1 drop per minute is at 20C and 50% RH = 3ml/hr (0.05ml/drop). At that temp/RH, there is 0.01 kg moisture per kg of air. But in hot, humid weather (say 35C and 90% RH), there is 4x as much moisture in the air. More importantly, at 20/50% the dew point is 9C, or a delta T of 11C that the (horribly inefficient) peltier cooler must keep just to condense moisture. At 35C, and 90% RH, the dew point is 33C, requiring only a 2C delta T across the cooler, allowing more of the power to be used for the latent heat of condensation.
Is it just my observation, or are there way too many stupid people in the world?
mmm.. hot and humid weather, this sounds perfect to use in a city like Guayaquil, Ecuador
Totally practical along the foggy coastlines. There are moisture retention fabrics that are then used for drip systems to water plants in drought regions. This invention seems like another advancement in that line of tech. Very practical for an outdoor rabbit hut.
One way or another, this will be vapourware.....
a) It is "a gadget created by Kristof Retezár, an industrial design student at the University of Applied Arts in Vienna."
b) It takes water vapour, or humidity out of the air.
Hmm, the humour and sarcasm seem to have been be lost on you.

Just like most every other so-called green solution, this one has a not-so-rosy underbelly: what happens if this becomes a popular device and everyone is using them? What effect will that have on local and global climate to have so much ground-level moisture removed from the air? This is not unlike the underbelly of windmill farms that just happen to kill birds and bats and also alter the local climate by removing energy from the weather system.
I've trained for (and completed) a marathon and done some long-ish bike rides (several hours), not to mention taken long hikes and hours of physical labor / yard work in both the burning heat and freezing cold. The water provided by a Camelbak or a couple bottles was enough to keep things together, and the extra weight wasn't exactly killing me or making the activity impossible. If you are decently hydrated to start with, doing an hour of reasonably difficult exercise is perfectly doable with no water at all.
Seems that this is kind of over-design for the vast majority of activity profiles -- people who work out for an hour a day are already rare enough, let alone people who work out long enough to have water weight be a significant part of the weight they are moving.
Just invent powdered water, that way...oh, wait.
But you could have just linked it, too: http://tech.slashdot.org/comme...
It really is not a real problem that needs a solution.
Its a technology that needs a demonstration platform. I wouldn't read too much into cycling being used for these demonstrations.
Correct me if I am wrong, but distilled water is harmful to the body as it flushes out salts and minerals. It can actually kill you at larger quantities. So why exactly should I drink distilled water when my body needs the minerals (i.e. during sport)?

How many "it magically pulls water out of the air" stories do we have to read? Condensation is nothing new. It's not amazing or even particularly interesting.
Why not just design a system to purify sweat?
No, Free After Rebate will not apply with this product. It hasn't even launched yet.
Distilled water is just what you need to quench your thirst after a physical excercise.
Really? Distilled water after exercise is so bad for you, you'd be better off skipping the exercise entirely. Fresh urine from a sick person would be much healthier than distilled water.
Where does slashdot get all the idiots these days.
... is that they'd better have those units in the south range repaired by midday or there'll be hell to pay.

No way this is replacing my stillsuit ...
Just where is this humid air going to be found, eh?
Yep, right next to your skin.
I'm currently cycle touring in central Africa and while this sounds like a potentially useful addition to my water supply solution (Katadyn water filter), it would not be a replacement for it. The main reason is that at 0.5 litres an hour (max capacity) it just wouldn't produce enough water for me. Currently, in ~30C temperatures with 80%+ humidity, riding 80km+ a day, I'm getting though upwards of 6 litres each day. It's thirsty work!
Clever but as they've just shown the entire world how to make it we'll have to see who actually brings it to market first.
