For sustainable society


Sun powered refrigerator

There was an era in Japan where the three types of home appliances, TVs, washing machines, and refrigerators, were called “three types of sacred treasures” as symbols of a wealthy life. In the midst of the rapid economic growth period, these home appliances have become an ordinary household item. From that era, more than 50 years later, there are still approximately 1.2 billion people in the world who are granted the use of electricity. 

YOUMMA of Brazil, has developed a solar-powered refrigerator “NILO” to support those living in the remote, off-grid areas without electricity. YOUMMA’s refrigerator has won the “Global LEAP Award 2019” in the contest for off-grid home appliances. It is expected to help to improve the quality of life of people without electricity infrastructure and contribute to the resolution of hunger issues.

The Global LEAP Award is a competition where manufacturers contest for the energy efficiency of their products. The aim is to develop and expand the developing market of the remote areas to have access to electricity as well as home appliances. Nowadays, energy efficiency has become more and more important when it comes to making electric appliances. And to be honest, there is no good in distributing solar powered refrigerators in developed countries where everyone has access to electricity.

According to the award, refrigerator design is particularly difficult to balance with energy efficiency, durability, and other features, among other appliances. There are 2 types of YOUMMA’s NILO, a compact size with a capacity of 42 liters and 96 liters, and the rated power consumption is 13.3W and 17.8W, which is about the same as one general LED lamp. It consumes about less than half the power of modern refrigerators of similar size.

At the Global LEAP Award, NILO was highly applauded due its desire to work with manufacturers to assemble products locally. Assembling the products locally will reduce manufacturing costs and create more jobs for the locals. The price hasn’t yet been announced, but it is estimated to be cheaper by around 40% when compared to a regular refrigerator.  

YOUMMA’s goal is to improve the quality of life for people who live in areas without power infrastructure. In countries outside of Japan, if food can be preserved, time for labor and other activities will increase, which gives a high opportunity to improve the quality of life. It took a huge development to get the electricity going, but it doesn’t hurt the environment to use this refrigerator. One step closer to a sustainable future.
