Who knew clean water could be so easy?

This little tidbit yesterday caught my eye. Apparently scientists in Switzerland have discovered that you can get clean, drinkable water by simply sticking it in a bottle outside.

Ok, there's more to it than that. The bottle has to be clean, clear plastic, no larger than three liters. It needs lots of sunlight and heat, which can be enhanced by setting the bottle on a sheet of corrugated iron, steel or aluminum. The variable then is the amount of sun the bottle catches. The process can take anywhere from six to 48 hours.

Nonetheless, a fascinating development for development.
