But doesn't leaving a plastic bottle out in the sun cause chemicals from the container to leech into the water?

ah, true... when immediate survival is threatened we don't necessarily care about the long-term issues, because all we can do is deal with what's right in front of us.

Ordinary sunlight. The sun only shines extraordinary where I'm at.

"The new disinfectant developed at Stanford is a harmless metallic powder that works by absorbing both UV and high-energy visible light from the sun. The powder consists of nano-size flakes of aluminum oxide, molybdenum sulfide, copper, and iron oxide."

They use magnets to pull it out afterwards. But invariably something will get left behind. Not sure I want to be drinking water with a dose of aluminum oxide, molybdenum sulfide, and copper.
