A team of researchers from The Australian National University have discovered a way to remove salt from seawater using nanotubes made from boron and nitrogen atoms that will make the process up to five times faster.

RainCloud
Anyone with a home dehumidifier knows water can be sucked out of the air. Cleanworld Ltd. in the UK designed the RainCloud C-15 for your home or office. Simply put, it's a small dehumidifier with a built-in water purification system to produce drinking water, with hot and cold options.

DC Water Film Motor
From Slashdot:
KentuckyFC writes: "Last year, a group of Iranian physicists made a puzzling discovery. They placed a thin film of water in a small cell and bathed it in two perpendicular electric fields. To their surprise this caused the water to rotate. They called their device a liquid film motor and posted on the web a cool set of movies showing the phenomenon. The puzzle is this: the electric fields are static, so what's driving the motor? Now another group of physicists has the answer: a complex interaction between the electric field, the cell container and the liquid causes water to move along the cell wall. Crucially, it moves in opposite directions on opposite sides of the cell and so sets up a circular flow. The phenomenon works only when friction and surface tension are significant forces so the effect is entirely scale dependent. That's probably why we haven't seen it before and also why it could have important implications for microfluidic devices such as lab-on-a-chip."

Atmospheric water generator
A device that pulls water from the air by cooling it to the point that condensation forms and then keeps it sterile for drinking.
Element Four’s WaterMill is a 300‑watt generator that makes up to 12 liters of drinking water per day—enough, it says, for your typical North American household.
