Watercone® The Product

It’s been a while since I’ve raved about this simple invention, but when I saw slashdot going on about some expensive solar PV powered water cleaning device, with all high tech moving parts that could break down or add drastically to expense, I thought of this.

It’s so simple… 2 or 3 bits of plastic! No solar PV! No moving parts! Just easy to deploy, stackable plastic cones.

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..

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.

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.

I would add a 4th step, and that is as you lift the watercone, wipe the bottom with a cloth. This will clear away any last drips of brackish or nasty water from the cone before turning it upside down. We don’t want any dangerous polluted water dripping through the central opening down into the bottle we’re going to drink from!

    is the water safe?

      Good question, which made me insert the diagram that somehow went missing, and also helped me think of adding Step 4 above. As the watercone sits on the polluted water directly, I think the bottom should be wiped before it is turned upside down, or polluted water might accidentally drip through the large opening in the bottom and mix with the clean water from the troughs as it flows into the cup/bottle we’re going to drink from! We don’t want that.
