The AquaPak is a small device that can pasteurize water. The pack uses solar energy to heat the water that has been placed inside up to temperatures to pasteurize it and thus make the water safe for drinking for both those out enjoying the great outdoors and for those that lack any other source of safe drinking water. 
In laboratory testing, the AquaPak killed 99.99 per cent of the pathogens that were present in the water. The pack achieves this by using solar energy to get the temperature of the water inside over 65 degrees Celsius. The pack can take four to five liters of water at a time and it can take around two hours to reach pasteurization temperatures. Simply fill it with water and lay it down flat in the sunlight. The pack can be refilled many times a day, allowing it to pasteurize enough water for a family of four to use in countries with bright, hot days.
The AquaPak is a cheap and simple method to provide safe drinking water to many people, thus significantly reducing needless deaths. The AquaPak is available for sale in many countries for use by those who enjoy life outdoors, for example camping or hiking. It allows them to reliably and efficiently rid the water they collect from rivers or streams from any pathogens.
