A refrigerator without electricity using solar

This refrigerator makes ice while the sun shines and uses this to remain cool for up to four days with minimal or no sunlight, now that is cool!

As many as 2 billion people around the world do not have reliable refrigeration. This is largely down to a lack of access to reliable and affordable electricity. More than an annoyance, a lack of refrigeration makes it difficult to store food for long periods, leading to food waste and forcing people, usually women, to spend more time shopping and cooking. This, in turn, limits the time available for paid work and relaxation. Koolboks, a company based in France and Nigeria, is hoping to improve access to refrigeration.

The company has developed a solar-powered refrigeration unit that can generate continuous refrigeration for up to four days, even with only limited sunlight. The Koolboks achieve this by storing electricity both in a lithium-ion battery and in the form of ice. When there is little sunlight or the battery is low, the ice can keep the refrigerator cold on its own.

In addition to keeping food cold, the power in the Koolboks can also be used to power LED bulbs (included with the refrigerator) and USB ports for charging phones. This makes the refrigerator ideal for use in off-grid areas.

Customers can pay in small installments through a pay-as-you-go scheme. This also enables mobile money payments and remote control of the refrigerator’s usage, billing, and performance.

Koolboks explains that the device makes ice during the day, using solar energy, adding, “at?night, when the sun?is no longer available, energy switches internally to the ice, maintaining the temperature of the cabinet?until the next day when?the sun is available again.?Thanks to this technology we’ve been?able to?bring down the cost of owning an off-grid solar refrigerator by?close?to 40 percent.”

This is a great negosyo idea in the Philippines since there are so many off-grid areas in the country without any electricity. As the Philippines is always battered with calamities, this is also a great backup option for emergency purposes.
