Believe it or not, you have still not heard all the ways that solar energy can be used to better the human experience. In Nairobi, Africa, a small poverty-stricken neighborhood called Kibera uses an interesting method of solar energy to purify water. By placing empty plastic water bottles on their rooves, the people of Kibera harness the power of the sun to clean the water placed on the roofs by residents of the area.
How does it work? Well it’s actually quite simple, much simpler than nearly any solar energy technology these days. There’s no solar water heater or photovoltaic cells, and in most instances, being in the grid is not a concern… there is no grid to be on! The natural rays of the sun, filtered through absolutely no technology at all purify the water.
Necessity truly is the mother of invention here. Until 2006 the Kibera area school suffered from enormous losses in active school days for many students who suffered needlessly with the kinds of infections that unclean water causes, most of which result in diarrhea and other intestinal upsets. By placing bottles on a special rack atop the area school to clean water, numbers of sick children began to diminish. Imagine, something as plain as energy from the sun made it possible for more children to be educated.
In the process of going back to school, the children were taught about the new solar water purification method and told to take the idea back home. The sowing of this seed has now saved loads of money and time being ill for the residents of Kibera; before they were forced to use unclean water or purchase it from somewhere as there is no water plumbed into the area.
Using solar energy to power your home is a great way to save money and maintain a greener lifestyle. For many more in areas like Kibera, solar energy is literally a lifesaver — and thankfully, a growing trend that will change the way people there live more fruitfully.
