Few days before I have started an orkut community "Rural Development of India". During the discussions, I came to know about following fact. I recommend you to join that community if you are really interested to do something for Rural People.  

Do you Know??

U can use sun rays to clean water (similar to AQUAGUARD functioning : that is, killing microbial orgasm in water). It is very simple. Just use your coke bottle and keep it in sun shine (see below pictures for full instructions). Please popularize this procedure by keeping in your website. Many poor people can benifit from this "no cost" procedure.

The Solar Water Disinfection (SODIS) process is a simple technology used to improve the microbiological quality of drinking water. SODIS uses solar radiation to destroy pathogenic microorganisms which cause water borne diseases.

SODIS is ideal to treat small quantities of water. Contaminated water is filled into transparent plastic bottles and exposed to full sunlight for six hours.

Sunlight is treating the contaminated water through two synergetic mechanisms: Radiation in the spectrum of UV-A (wavelength 320-400nm) and increased water temperature. If the water temperatures raises above 50C, the disinfection process is three times faster.

How do I use SODIS? (in pictures)
