Awesome, Low-Tech Gadget Creates Liters of Fresh Water

Sometimes the simplest technology is the best.
The Watercone, a solar-powered water purifier, is a testament to that.

The cone-shaped device turns salty or dirty water into up to 1.7 liters of fresh water in a matter of hours, according to Watercone.

Here’s how it works: You pour the bad water into a black pan, and then you screw on a cone. The black pan absorbs sunlight and heats up the water. Then, the evaporated water condensates into droplets on the cone’s inner wall, and the droplets drop into a circular trough at the inner case of the cone. After a few hours, you can unscrew the cap, tip the cone upside down and empty out the clean water into a receptacle.

The Watercone is due out this summer, and it should cost no more than $30. This will be a tremendous help for poorer, developing countries.
