Did you know that refrigerators were first introduced into modern homes in 1913? Today, we really take that technology for granted. We expect that we’ll always have the ability to keep foods cool and fresh in the comfort of our own home.

However, just a century ago that assumption simply wasn’t a reality. And it still isn’t a reality today in developing countries. People in developing countries struggle to keep fresh food at the ready. If they had better power grids, they’d be able to use modern refrigeration. Reality is that modern refrigeration isn’t an option.

‘Just add water and the Evaptainer does the rest.’

The founders of Evaptainers took a look at this challenge and decided they could do something about it. They took a look at history and evaluated how people kept food cold before modern refrigeration. Then they came up with a solution that’s pretty genius.

Evaptainers can keep food cool using nothing more than water and the power of the sun. That’s right – no electricity is necessary to use an Evaptainer. All it takes is 6 liters of water to keep 60 liters of produce cool for 12 hours. That’s enough to change the lives of people and farmers in developing regions.

Evaptainers work by harnessing the power of evaporative cooling to keep food fresh.

  • First, they have an inner compartment, which houses the food.
  • Second, they have an outer compartment, which houses an evaporative medium (like sand) and water. As the water evaporates, it cools the air in the inner compartment, keeping food cool.

While the final Evaptainer prototype is currently being tested in Morocco, speculations suggest that Evaptainer units will only cost $10-20 each. That is incredibly more affordable than a refrigerator — plus the cost of electricity in an area where the power grid is weak.

Not only could these units completely change the lives of people in developing areas, they could have a nice impact in first-world countries too. Farmers could use them at Farmer’s Markets to keep their produce fresh longer during the summer months. The applications are endless.

Evaptainers are expected to be released on the market sometime after the testing period ends during the summer of 2015. You can sign up to be notified when they are available for purchase.
