A portable water purifier for drinking sea water!

We have always studied since school days that 70% of the earth is covered with water but most of it is not drinkable due to sea’s salinity and minerals. Its been man’s desire to always be able to harness this seemingly limitless source of water for drinking purposes. We have made significant progress with that but never had a portable device ever.

This is one product that would have really come handy to Robinson Crusoe or Tom Hanks in the Adventure Drama named Cast Away or the most recent Thriller ‘Life of Pi’. Being able to drink sea-water is like a dream come true for every sea traveler and mariner. There are some large devices which have been developed for this purpose and converts sea water into drinkable state. But none of them are portable and not fit for storing in your bag. Designers Younsun Kim, Kangkyung Lee, Byungsoo Kim and Minji Kim have developed a product which solves all these purposes. Its named the Puri – Sea Water Desalination Bottle.

The Puri works on the concept of Reverse Osmosis and has been put in a very compressed and compact form inside the bottle. This regular sized bottle draws the saline out of the water and into the bottle’s yellow filter. The remaining water is then safe to drink, which could mean the difference between life and death in a sudden marine emergency. See the process flow of the bottle below.

Getting rid of Mosquitoes got a lot more easy

Mosquitoes are a menace in the tropical weather. Ask any Asian or African citizen, and you would know what dangers a tiny flying insect can have. Every year millions die from Malaria, Dengue and other such ailments that happen through mosquito bites. Repellents and sprays have their own harmful side effects and are not always effective. The team at The Kite led by  Grey FrandsenDr. Michelle Brown and Torrey Tayanaka have come up with a brilliant patch that can make humans nearly invisible to mosquitoes. The work is still in testing phase but holds a lot of promise for the 3rd world countries where Malaria and Dengue are a major concern.

Each disposable square patch measures just 1.5 inches (38 mm) per side, and is simply stuck onto the clothing like an adhesive decal. A proprietary blend of FDA-approved non-toxic ingredients within the patch then exudes a scent, that reportedly blocks mosquitoes’ ability to detect exhaled carbon dioxide – that’s the major method by which the insects track down their human prey. Once exposed to the air, the patch remains effective for 48 hours.

Kite’s™ technology stems from scientific developments initially developed at the University of California, Riverside with assistance from the Bill and Melinda Gates Foundation, and the National Institutes of Health. Initial large-scale testing is planned to take place in Uganda, where disease-carrying mosquitoes are a major health issue. Ultimately, it is hoped that Kite patches will be widely available both to aid organizations, and to consumers around the world.
