Coolfinity IceVolt 500
The Coolfinity fridge only needs 6 hrs of power/day to cool 24 hrs at a very stable 3 dC under tropical conditions. Further it has a holdover time of 48 hr to safely store food (dairy, fish, meat) & medication (vaccines, oxytocin, insulin). The very energy efficient fridge can also rapidly cool down warm content (e.g. fresh milk from a cow) even without power. Moreover the fridge eliminates the need for polluting, noisy & costly diesel generators. In the near future a solar version is available.
