An Austrian start-up has revealed plans to start selling a self-filling water bottle that extracts humidity from the air and condenses it into drinkable water at a rate of up to 0.5 litres per hour - provided it’s a really humid day. Developed by the team at Fontus, the solar-powered device uses hydrophobic surfaces to repel and funnel the drops of condensation in the bottle, which means so as long as the air around you isn’t too polluted, you'll have access have a constant supply of clean drinking water. "This is simply condensation of the humidity that is contained in the air," Fontus founder Retezár Kristof told Denise Chow at Live Science. "You always have a certain percentage of humidity in the air, it doesn't matter where you are - even in the desert. That means you would always potentially be able to extract that humidity from the air." The water bottle - which is currently getting the crowdfunding treatment to facilitate mass-production - is being marketed as an aid for long-distance cyclists who don’t have time to stop off and top-up.

When it goes on sale, it’ll come with a bike-attachment, as seen in the video below.indoor plants as air purifier That’s the first-world application of the technology, but the benefits are obvious for the 1.2 billion people in the world who are living in areas where clean water is scarce.best air purifiers for $100 "The idea was to solve a global problem: water issues in areas of the world where there is very little groundwater but very high humidity," Retezár said. "lens cleaning kit microscopeMy intent was to invent a machine or device that would be able to filter the humidity in the air and turn it into drinkable water." The device is made up of a solar panel, a condensing chamber lined with hydrophobic surfaces, and a very basic filter to keep dust, dirt, and bugs out of the mix.

It works by taking in warm, humid air, which is condensed down into water droplets that are funnelled into the water bottle below because the hydrophobic surfaces prevent them from sticking. "Because they're hydrophobic, they immediately repel the condensed water that they created, so you get a drop flow [into the bottle]," Retezár told Live Science. "Basically, you're taking air in a vapour state and converting it into a liquid state." When it hits the market, the bottle will come in two models - the 'Airo', and the 'Ryde', which is being made specifically for cyclists. Retezár and his team say if you've got with temperatures 30 to 40 degrees Celsius (86 degrees to 104 degrees Fahrenheit) and 80 to 90 percent humidity, you can hit that impressive 0.5 litres per hour fill-rate. The developers have also mentioned the possibility of adding a carbon filter to the mix, which could be used to filter out clean water from more polluted areas. Now, all of this does sound pretty awesome, but of course it does - Fontus wants to sell a lot of these things.

While the principle of the thing sounds like it would work as advertised, until we see tests from independent parties, we have to remain skeptical. According to Eric Mack at Gizmag, the company says it plans to release third-party white paper data at some point, which will include "reference temperature, humidity settings, duration, and resultant volume of water created", and separate 'validation tests' are going to be funded by some of those crowdfunding dollars.ShareFacebookTwitterGoogle+StumbleWater Globe Air Freshener and PurifierMy kids are allergic to dust and feathers and chemicals in the food and a few other things. So I am a bit desperate to make my home an environment that is as clean as possible in order to keep them healthy. But dust is the major problem I have since I live in a city and my apartment is on the ground floor of a building that is situated near a heavy traffic road. Well, no matter how careful I am and what filters I use, I still have to open the windows for the morning air and after a few minutes the dust piles up on my furniture.

Apparently now there is a way to get rid of it as some smart guys invented the Water Globe  Air Purifier and freshener. This is a magic globe that is filled with water and uses it for filtering the air in a room. So the water acts as a natural filters for the dust, the spores, the pollen and all the other harmful microscopic formation in the air. So you do not need any filters that you need to change regularly and which come only in one size and also no need for you to breathe the unhealthy air.It has more than one helpful feature, because it can also be used as a humidifier when the air in your house is too dry and also spreads a nice scent in the house. You actually can choose the scent and you will benefit from all these for only $70. Or at least this is the price on Sharper image. Dispatched from and sold by Electro World.

Water lasts and doesnt need changing daily.- Beutiful lights which are subtle and relaxing- Really freshens the air and in a large area- The scent fills the room and eliminates odours- Ioniser can be turned on/off independantly- 3 scent bottles included for free (I had Jasmine, Lavender, andCONS- Quite loud on highest settng (of 3) but still quite a relaxing noise- The instructions are minimal and dont discuss maintenance- The scent bottles are quite small and £8 each to replace but you only need a few dropsIN CONCLUSIONI have just spent £650 on a Blueair 650E SmokeStop top of the range air purifier and its awesome (see my review) but when one remembers that this was £630 cheaper and achieves a lot of the main features it is pretty amazing.

If you have serious allergies, health issues or air contaminants then you will need a product such as the Blueair. If however you have mild allergies, odour problems or dry air from central heating then this product will meet your needs admirably.I have mine set up in a room that is approx 28 x 15 feet so im asking it to deal with a large area inhabited by 2 smelly dogs and 2 smelly humans! In the winter we have the central heating on a lot which dries out the air terribly, and odours tend to hang in the air. See all 949 customer reviews (newest first) I never used it but I gave it away to someone who was suffering with asthma.They were really happy Only lasted 3 months then just stopped working rubish don't buy !!!! Does what it says and keeps the air fresh and eliminates cooking odours. Difficult to clean the rotor arm which gets gunged up with the impurities from the air.. Fairly good at what it does, however it gets very dirty very easily and the water can quickly build up limescale.
