The Watercone®

The Watercone® is a solar powered water desalinator that takes salt or brackish water and generates freshwater. It is simple to use, lightweight and mobile. The technology is simple in design and use and is discribed by simple pictograms. With max. 1,6 liters a day the Watercone® is an ideal device to cover a childs daily need of freshwater.

Passive Solar One Step Water Condensation FTW!

We wrote about the Watercone, but considering how much TreeHugger’s audience has grown since then, it’s likely that only a handful of you were reading the site back then.

I think it’s time to have a second look at this very clever device that has the potential to help provide clean drinking water for millions of people who are lacking access to clean water (or if they do, maybe the access is intermittent and they could use a plan B).

This could save many lives for sure.

Read on for more details and a demonstration video.

Step #1: Pour salty / brackish Water into pan.

Then float the Watercone(r) on top.

The black pan absorbs the sunlight and heats up the water to support evaporation.

Step #2: The evaporated Water condensates in the form of droplets on the inner wall of the cone. These droplets trickle down the inner wall into a circular trough at the inner base of the cone.

Step #3: By unscrewing the cap at the tip of the cone and turning the cone upside down, one can empty the potable Water gathered in the trough directly into a drinking device.

It’s also very durable, easy to transport (they stack easily), inexpensive to produce, and low-tech enough that it can be used even if no other infrastructure is present.

One thought on “Clean Water for Every Day

  1. Organic gardening has become increasingly popular with the movement back to natural foods and unprocessed products. Many people wonder how to start and organic garden.

    It i\’s actually not difficult, expensive, or time consuming. The toughest part is getting started because once you have the base for your garden the rest is just easy maintenance. And you will love the quality of the food you grow and knowing it is healthy for you.
