The most abundant resource for the continent of Africa has got to be the sunny days that they have. In a science project that makes full use of this abundant natural bounty, a company called Palfridge is making solar powered refrigerators. Using the natural heat of the sun to keep things cool in the ice box.

The Swaziland based Palfridge has already manufactured more than sixty thousand sun powered refrigerators. The eco-fridges have been the first of their kind on the continent of Africa. There is great demand of these sun powered refrigerators in neighboring South Africa as well.

What makes these fridges truly eco- friendly is the fact that they use natural refrigerants that the German Society for International Cooperation came up with. The fridges are used essentially to keep food and medicines cool in areas that are devoid of electrical power supply at present.

It is a great way for doctors to ensure that vaccines stay at the optimal temperature in the rural interiors. Even with no sunshine the refrigerators continue to work managing to keep the contents cool for up to five days. A truly useful science project that will positively affect the world.
