From the wikipedia link > At the 2007 TED Conference, Adam Grosser presented his research of a new, very small, "intermittent absorption" vaccine refrigeration unit for use in third world countries. The refrigerator is a small unit placed over a campfire, that can later be used to cool 15 liters of water to just above freezing for 24 hours in a 30 °C environment.

The person that from the Ted Talk linked to has a very similar device to the one shown in the BBC Article and with the exact same goal to help transport vaccines and similar through developing countries.

Congrats to the kid but something seems a bit suspicious...
