The arctic is warming at twice the rate as the rest of the world, which means the sea ice is shrinking at a rapid rate. The arctic has its lowest amount of sea ice since scientists began monitoring it by satellite in the 1970s. It begs the question, can't we just refreeze the ice? The answer might actually be, "yes."
A team of Indonesian designers want to produce iceberg-making submarines. The team, led by architect Faris Rajak Kotahatuhaha, plans on creating a submergible vessel, which sounds a little bit like an elaborate ice cube tray. The submarine sinks below the surface of the sea, filling up a cavity with seawater. The salt is removed, and the water is frozen using a "giant freezing machine." The result is 16-foot thick and 82-foot wide hexagonal icebergs, which are then released into the sea. Why the hexagon shape? It allows the icebergs to interlock with each other, forming larger masses of ice. Each iceberg would take a month to create. The idea was recently named runner-up in an international design competition for sustainable ideas.
