Every little helps! Solar Disinfection of Water, or SODIS
from Willis Eschenbach
.....The idea is bozo simple. Put water into a clear plastic bottle. Shake it up well to oxygenate it. Put it out in the sun. Six hours in the sun and the oxygen plus the solar UV kills diarrhea.
I mean, how great is that? Now that’s solar tech I can get behind 100% … plus it uses up old water bottles. And doesn’t require any chemicals. Brilliant. Get the word out. Kids’ lives are at stake.

Another blogger adds
"75% reduction in infection. At zero cost of fuel, fuel being a major expense in those societies where the technique will be useful.
Perfection is expensive. A vast improvement is cheap.
Which is preferable?"
