A 22-year-old student in the UK has
invented a mobile fridge that can store vaccines at an ideal temperature while
in transit, which could potentially save millions of lives. Current methods of
transporting can result in the vaccines freezing before reaching their
destination in countries where poverty and conflict are major obstacles. The device,
called Isobar, maintains a steady two to eight degrees for 30 days. It heats
ammonia and water to create ammonia vapors, which are then released into its
main chamber when cooling is needed.
