Small constructions to distill water

Researchers at the SLAC National Laboratory not stop fighting for inexpensive method of purifying water for people who do not have access to drinking water. Recently they created a small device about the size of a postage stamp, which in 20 minutes can purify 25 liters of water contaminated with bacteria, requiring for its operation only sunlight! The device eliminates up to 99.9% of bacteria, but the only downside is bactericidal. Scientists do not give up. They hope to soon expand the scope of operation. Good luck!
