How to Build a $3 Solar-Powered Water Purification System
2 January 2011 | Solar Power | No Comments
Last year we talked several times about many water purification devices, but none of them wasn’t as cheap as this new solar powered water purification system developed by UW students.
The idea of using solar rays to clean water is an old one. Usually when solar rays pass through a plastic bottle filled with water, it removes more than 99.9 percent of bacteria and viruses. Sun rays can be very efficient in cleaning water, but to do this it takes some time (the water can not be instantaneous purified) and we don’t know when their job is done.
Europe to get powered by solar panels placed in the Sahara

In the perspective of a “greener” future, today’s projects bring us closer to that reality and make big promises: covering only a small portion of the Sahara dessert, having a probable size of a regular European country, with solar cells will potentially provide the whole of the European continent with electricity. That is what Anthony Patt, of the International Institute for Applied Systems Analysis, in Austria, declared at the International Scientific Congress on climate change under the title “Climate Change: Global Risks, Challenges and Decisions”, held at the University of Copenhagen in March this year.
Best Water Purification Methods Explained

We decided to explain the best water purification methods in order to help people understand how hard is for the world governments to provide clean healthy water for all of us . If nowadays the large part of the urban societies are used to pay for, either mineral water or some other type of water-based drink, the availability of clean, fresh water should be a benefit to every human being
on this Earth being a basic human need!
