A crash course in changing the world.
A lot of people have the possibility to get enough water – but often not enough clean water. Especially in Africa this is one of the most common cause of death. Brackish water causes illnesses like diarrhea or ch***ra.
SODIS is a very simple possibility to kill most of the causative organisms with just a simple PET bottle.
For most of the affected people it is not possible to cook the water before using because timber is too expensive. But 25 years ago, a Lebanese explorer found out that water in a PET bottle he found had no causative organisms any more. WHY?
After years of analysis and testing the secret is not disclosed at all, but it is sure that if you lay a clear plastic bottle with brackish water in the sun for 6 hours, all causative organisms are dead. The part of the sunlight which let our skin get brown – the UVA radiation causes damages at the organisms just until 20°C! When it gets warmer (and in Africa it will get warmer) the membrane of the germ gets completely damaged and the organism will die. Ch***ra germs die at 40°C, most of the others at 45°C. The bottles can be bought for only very less money or are part of donations.
