THE WATERCONE

is a mobile, lightweight, easy-to-use and portable one-person solar still, which transforms saltwater (e.g. seawater) into purified drinking water alone by way of sunshine. The technology is simple in design and use and its use is described in simple pictograms which you can find in Downloads. With up to 1 ½ liters in 24 hours the Watercone® is an ideal device to create a child’s daily need of freshwater.

UNICEF: "Every day 5000 children die as a result of diarrhea caused by drinking unsafe water."

What is the Watercone®?

The WATERCONE® system is a one step water condensation process with a 40% effectiveness degree (GTZ Germany). Based on evaporation levels of 8.8 liters per square meter (average solar irradiation in Casablanca, Morocco), the WATERCONE® (with a base diameter of roughly 31.5", 80 cm) yields between 1.0 to 1.5 liters of condensed water per day (24 hours).

Philosophy of the Watercone® concept:

"Many peripheral, de-centralized small units will ensure a better supply of freshwater than one central big generator. If the big one fails, there is no water generation for anyone. If a small one fails, the other ones still keep on working.“

step 1

Pour salty / brackish water into pan. Then float the Watercone 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.
