Here is an excerpt from a recent article about using sunlight and nano particles to produce clean water:
An invention from Down Under uses sunlight and nanoparticles to purify water on the cheap.
Project leader Eldon Tate, a nanotech researcher and PhD candidate at Victoria University in Australia, is hoping to break new ground in water purification.
“The idea of harnessing the power of sunlight to purify water in developing nations is not a new one but, so far, no-one has cracked the magic formula of an efficient and yet inexpensive system, Tate says,” according to Stuff.
The invention works with anti-bacterial nanoparticles, which harness the sunlight to crunch down organic contaminants, Tate said in the report.
