More than one billion people around the world do not have access to safe clean water. Every day 6,000 children die from drinking dirty disease-ridden water. In a truly life-saving lesson, the teacher in the film explains to her pupils that heating water up is an effective way to make water safe to drink.
Solar cooking is a cheap and easy ways to pasteurise water.
“Pasteurisation: the process of heating liquids for the purpose of destroying bacteria and other microorganisms that can cause disease”
It saves money because you don’t need firewood to boil the water and it saves time because you don’t have to continuously check the fire. The film shows a clever piece of kit called the “WAPI”. WAPI stand for WAter Pasteurisation Indicator. It contains wax that melts when it reaches the right temperature for safe drinking water,so there’s no confusion about when it is safe to drink the water. This is a simple technology that can save lives.
The new solar power cooker shown in the film is known as the “Cookit”, and is made of cardboard with reflective silver foil panels on one side. Sunlight is reflected onto the pan as it sits inside the Cookit. As well as pasteurizing water, the Cookit can be used to cook food too!
Nyakach is a small area near Kisumu in Western Kenya. Despite being near Lake Victoria it is one of the driest parts of Kenya. It sits on the equator and has intense sunshine for over 6 months of the year and some sunshine on at least 300 days a year. In Nyakach, many people are poor and the area has been hit hard by AIDS. The local population is around 110,000 people.
