Clean water isn’t option for people in many parts of the world, but a new device half the size of a postage stamp may change that. Developed by researchers at Stanford University, the device can harness the power of the sun to disinfect a container of water in as fast as 20 minutes. All you have to do is drop the miniscule solar machine into the water you want to cleanse and leave it outside for a bit. Especially in places where sunshine is abundant, this device could be a major life-saver by ensuring people with clean water.
