They call it 'Design for the Other 90%'. The Cooper-Hewitt National Design Museum is holding the exhibition to emphasis that popular design benefits only 10 per cent of the world's population, as only they can afford most things. The exhibition showcases 30 design projects addressing basic needs in developing countries.

The LifeStraw (in pic) is a water purifier which turns any surface water into drinking water. Other designs include a bamboo treadle pump for farmers to pump up groundwater, the Big Boda Load-Carrying Bicycle for carrying cargo or two passengers, and the Q Drum which helps people transport water by rolling the tyreshaped drum along the ground, rather than carrying it. The most innovative is One Laptop Per Child's X01 laptop computer that costs around $200.
