A team of MIT researchers is using the thermodynamic properties of water evaporation to bring off-grid cold storage of produce to remote, arid regions.
The team’s models indicate that a standard 40-foot-long shipping container outfitted as an evaporative cooler will be able to store between 6,500-8,000 kilograms of produce. The cost of constructing the chamber will likely be $7,000-$8,000, which, compared to mechanically refrigerated options of a similar size, offers over a 50 percent reduction in cost, making this new design very lucrative for farming cooperatives. One of the ways the team is keeping the production costs down is by using local materials and a centralized manufacturing strategy.
