solar water purifier

the website below says this solar water disinfection device
which can be attached to a pet bottle will make the water
in the bottle  potable with a few hours of exposure
using just the uv rays of the sunshine; no chemicals or electricity.
the site says it is going to test the device in odisha in a big way.
u can get the device called WADI for about 50 pounds now.
the ultimate price when distributed on a large scale will be
much less.
