Fenik are electricity-free mobile refrigeration units which run at low-cost. Utilizing the phenomenon of evaporative cooling, food is stored in a double-walled container where water evaporates through the porous outer wall, thereby cooling down the inner container. Compared to the rather more energy-intensive vapor compression refrigeration, they are ideal for use in off-grid rural areas with low relative humidity.

Solution:
This is a technology developed to roast coffee beans using sunlight – the energy source most widely available to farmers. The solution concentrates the rays of the sun on a rotating drum containing coffee beans. The sturdy device has been developed for use in rural areas and can be maintained locally, boosting its resilience. With the capacity to roast 1 kg of coffee beans in approximately 15–25 minutes, this roasting technology is fairly comparable to the timelines and capacities of conventional roasting equipment of the same dimensions.
