A joint research with the Nature Nanotechnology team at Stanford University in the USA claim to have created a tiny device that uses the sun’s power to purify water, in just 20 minutes! That is ground breaking technology!

When in water, this device absorbs sunlight in the way most solar devices do not, efficiently, and uses this to cause a reaction that kills bacteria. The test killed off 99.9% of the bacteria in 20 minutes! If you want to read more, please click here!

Boy is this good news for many parts of this blue globe we live in.  1.9 billion people, that is almost a third of the world, are said to drink water that is faecally contaminated according to WHO! Needless to say this technology will be seeing the light of day soon!
