Disinfecting water can take a lot of time to create clean drinking water. New technology by the Stanford University researchers and the SLAC National Accelerator Laboratory allows something very small to work very quick with that task. It looks like a small, black rectangle and uses solar energy to disinfect the water. The rectangle reacts with sunlight to release bacteria killing chemicals into the water source, leaving purified water in its wake.

Key Takeaways:

• One of the major crises facing the world is access to clean drinking water.
• UV rays are a good disinfectant, but can take up to 48 hours which limits the amount of water people can treat at a time.
• Stanford University researchers created a small device that when dropped in water uses solar energy to disinfect it in just minutes.

“With that in mind, the researchers created a small device that when dropped in water uses solar energy to disinfect it in just minutes.”
