Yi Cui, an Assistant Professor of Material Science and Engineering at Stanford University, has invented quite the water filter. It’s inexpensive, is very resistant to clogging, and uses much less electricity than systems that require the water to be pumped through them. It also kills bacteria, as opposed to just trapping them, which is all that many existing systems do.
