Clean Water for the Developing World

Abstract:
A water filter under development at Stanford University removes bacteria from water quickly and without clogging--and could lead to a simple and inexpensive method of cleaning water for the developing world. The device, which uses a piece of cotton treated with nanomaterial inks, kills bacteria with electrical fields but uses just 20 percent of the power required by pressure-driven filters.
