Sterilize drinking water using the heat of the sun.
SODIS - solar water disinfecting with soda bottles and sunlight
Solar water disinfection, or W, is a method to disinfect water using sunlight and PET bottles.

You can pasteurize water in clear plastic bottles by exposing them to the sun.

The <a href="http://www.sodis.ch/">Solar Water Disinfection (SODIS)</a> 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 50°C, the disinfection process is three times faster.
You can raise the temperature of the water in transparent bottles by putting them in the sun against a dark background.
Simple Solar Rules: Dark heats up Light reflects Clear keeps off the wind
