The future of refrigeration may be smaller than you think

Fonterra, a major dairy company in New Zealand, is currently looking at transporting milk using temperature-controlled drones, bypassing road infrastructure and increasing speed of delivery.

Unmanned aerial vehicles (UAV), commonly known as drones, were initially developed for military use and are operated by a remotely located pilot. Today, drones are increasingly being used by civilians for a variety of purposes including recreation, commerce, science and agriculture.

Researchers at Johns Hopkins Medicine (USA) have also developed refrigerated drones that can safely transport medical supplies such as blood, medications, and vaccines. Researchers have perfected a system of cooling on drones which can keep blood carried in specially refrigerated coolers at the correct temperature during drone delivery. Solving the problem of refrigeration makes the use of drones to deliver blood supplies or other medical supplies more realistic.
