One of the best products in NextFest organized by WIRED magazine is LifeStraw, a personal water-purification device that disinfects water by using filters down to six microns, to remove bacteria and parasites from any water sources.
Each LifeStraw filters up to 700 litres of water (for a normal 60 kg adult who consumes 2 litres of water per day it last for 350 days) with a price tag of only $3 USD.
The device is developed by the Danish company Vestergaard Frandsen that introduces PermaNet and Zerofly- a Malaria Disease Control Textile, to the world. I especially like their specific terms of combining Imagine+Engineering- “Imagineering”, I am so sick of all the bullshit designer products float in the market doing absolutly nothing besides “looking good and match your 2 million dollars loft.” Hey I-D dudes make something useful and benefit people around the world, not only for filthy rich fucking assholes!
