Solvatten - how to get fresh water from the sun

Solvatten (Sun Water) is such an amazing invention!

Petra Wadström came up with this idea when travelling with her family in Indonesia in 1997, and it took her ten years of research and testing before production could begin.

Solvatten is a container of 10 liters that, when put in the sun, cleans water from bacteria, viruses and parasites. Apparently UV-light kills microorganisms as well as boiling does, and combined with heat and a built-in filter this really works. And without any chemicals being used! The container can be used in any country as long as there is sun. Doesn't matter if it's cold as long as the sun is out. Solvatten can produce up to 30 liters (8 gallons) of safe drinking water in a day.

It's so easy. You fill it up with water and leave it in the sun for two-six hours and voilà, when the indicator tells you the water is safe, you've got water ready to drink. It almost sounds to good to be true, but the water from Solvatten is approved by both WHO and FDA.

In many countries wood or charcoal is being used to heat up water to make it safe. In Africa 70% of household income is spent on that kind of fuel. Solvatten can help reduce that cost as well as help preventing deforestation.

Such a great and simple way to use free solar-energy and completely organic too!

You can find a long list of the organizations Solvatten cooperates with on their homepage.

I'm so proud of this Swedish innovator!
