Across the 7,000 islands that make up the Philipines - and indeed around the world - salt and water are fairly accessible commodities. Electricity, less so. So when it comes to light, millions of households rely on kerosene or battery-powered lamps, or even candles. The SAlt lamp provides a simple, sustainable solution - just one cup of water and two tablespoons of salt powers this nifty contraption for up to eight hours.

In disaster-prone areas such as the Philipines, SAlt can play a key role in making essentials like food, water, and light available to people in emergency situations - it can easily be stashed away and powered up if a typhoon or earthquake strikes. And for people living in coastal areas - a vast majority in the South Asian country - the lamp can even be powered on sea water.

Created by a Philippines-based team of young engineers and designers, SAlt is safer than most alternative lighting products - it contains no flammable parts or solutions. And to make it even more impressive, SAlt sports a USB slot that can charge a mobile phone when the lamp is turned on.

The innovative team is now hard at work making SAlt available for mass purchase, after focusing on local supply in the first round of produce. The lamp is a brilliant example of simple, sustainable design - that could change the lives of millions around the world.
