Solar Powered Portable Fridge
Green technology has made leaps and bounds in the past few years, especially in the field of energy. Let’s face it, almost everything done in the modern world requires a power source of some kind. But this power doesn’t need to come from burning fuels or from large infrastructures. There’s plenty of power to be had if you know how to harness it. One invention which is sure to be helpful both in the developed and developing world is the solar powered portable fridge.
In the developed world, refrigeration technology is practically taken for granted. The wonders which refrigeration provides a society are truly exceptional, especially if you consider than true famines are practically unheard of in countries which have it. Solar powered portable fridges bring this amazing technology to the developing world as well, ensuring that effort put into getting and making food isn’t wasted. It also helps campers, hikers, and other nature lovers around the world who want to take chilled food and beverages with them wherever they go.
A solar powered portable fridge is exactly what it sounds like it should be. It’s a portable refrigerator with a typical capacity of 30 – 100 liters which uses solar power in order to chill the contents. Portable solar powered fridges operate based upon evaporation, meaning that they don’t need power hungry heat pumps in order to function properly. Because they use less energy, they don’t even need expensive and fragile solar panels. While they do need to be recharged eventually, most modern units can go for several days while keeping perishable food at roughly six degrees Celsius (about 42 degrees Fahrenheit).
Each year that passes brings with it more advances in miniaturization and materials science. This makes portable solar powered fridges increasingly less expensive, meaning that they become ever more viable for developing countries where people don’t have hundreds of dollars to spend on refrigeration. Many countries like South Africa, Zambia, and Namibia use solar powered portable fridges quite extensively since there are many parts of the country that don’t have easily accessible electricity at hand. This helps to keep valuable crops and meat good for sale in market. Because the cost of refrigeration is cheaper this way, the cost of the food cheaper at market, making it easier for poor people to maintain varied and healthy diets. Solar powered portable refrigerators are truly amazing in their spread of prosperity to the developing world.
