Evaporation-based Water Purifier Cone

[Mobat555]

When you evaporate and condense water, the condensed water is 100% pure water. This means the purified water is completely safe to drink, as nasty chemicals and bugs do not evaporate with the water. The WaterCone is a very simple gadget that purifies water by the process of evaporation.

I remember learning how to make a solar still in Boy Sprouts back in the late 70s...same tech, but not as fancy.

One problem I see is you set your "clean" portion of the device into "dirty" water. There is chance for cross contamination.
