Watercone® Solar Still, solar seawater desalination

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 described by easy to understand pictograms. With max. 1,6 liters a day the Watercone® is an ideal device to cover a childs daily need of freshwater.

german innnovation at its best, well done.

Not a new invention.Used to do that in the army.Also nomads at desert do it.You dig a hole at the ground and u place a glass in the middle, a plastic above with rocks supporting it at the edges of the hole and one rock in the middle of the plastic.You leave it at night and u have ur glass full of water at the morning.

are they sure this is new? im sure ive read about this in " The Life Of Pi"

I can make it better, simply add some magnifying glasses to the cone, they can be done with the same plastic and they should have different diameters as they are cose or far from the plate.

Use vacuum deceleration

This seems like a great product, but distillation only seperates salt and minerals from potable water. I don't see how this product removes the cholera virus from the water.

According to the WHO, water must be sterilized either boiling to 180deg or treat the water by chlorination to effectively kill the pathogens in the water.

A vacuum desalination is the cheapest option

Using low pressure to make fresh water

@minero1986 Nah. The nutrients you need to survive are in food, all you need from water is water.

Even things like sports drinks contain a minuscule amount of electrolytes (no real calcium or magnesium and only 1/100th of the of the daily potassium you need to survive)

Places with more advanced water systems will add fluoride and some other goodies to tap water but it's not really key. The point here is to have something you can drink that doesn't have feces and viruses in it.

@misery9177 I believe "manufacturing" is the word you're looking for. And it's dirt cheap. Just two pieces of vacuum formed plastic, polycarb on the top and likely ABS on the bottom. You could set up to do it yourself just as well in your garage in a week or two with under $1000

The problem is that they can charge whatever they want for it for a variety of reasons that aren't really worth listing here but, in essence, they've created a socially responsible product then priced it irresponsibly.

@irakleitos123

that's a little different, that's condensation and collection of the condensed water vapor that becomes droplets upon cooling
