This ice-making submarine would pop out bergs to help fight climate change. A team of designers led by Faris Rajak Kotahatuhaha proposes re-freezing sea water in the Arctic to create miniature modular icebergs using a submarine-like vessel, in a bid to combat climate change. The Indonesian designer worked on the prototype with collaborators Denny Lesmana Budi and Fiera Alifa for an international competition organised by the Association of Siamese Architects. The team was awarded second prize in the contest for its geoengineering proposal to re-freeze the Arctic and transform sea water into new ice fields. The designers propose to delay climate change with submarines which produce icebergs
Artic ecosystem need to be restored
Kotahatuhaha's team set out to create a prototype for the 're-iceberg-isation' of parts of the Arctic by freezing seawater into hexagonal blocks of ice that nest together to form new ice floes.

Delay Climate Change With Submarines Which Produce Icebergs
The main goal of this idea is to restore the polar ecosystem, which has a direct effect on the balance of the global climate. The concept is a proactive response to issues related to the melting of the earth's polar ice. The designers felt that too much emphasis is currently being placed on protecting cities from rising sea-levels rather than tackling the problem at its source and delay climate change with submarines which produce icebergs.
The artificial icebergs wil increase the Albedo effect. (Also interesting: China Will Make It Rain In Tibet: Space Technology)
Albedo Effect
Albedo is a measure of the reflectivity of a surface. The albedo effect when applied to the Earth is a measure of how much of the Sun's energy is reflected back into space. Overall, the Earth's albedo has a cooling effect. (The term ‘albedo’ is derived from the Latin for ‘whiteness’).
The basic principle is analogous to strategies employed by people who live in hot places. Building are finished with white exteriors to keep them cool, because white surfaces reflect the sun’s energy. Black surfaces reflect much less. People wear light colours in summer rather than dark ones for the same reason.
The Earth’s surface is a vast patchwork of colours, ranging from the dazzling white of ice and snow, to the dark surfaces of oceans and forests. Each surface has a specific effect on the Earth’s temperature. Snow and ice reflect a lot of the sun’s energy back into space. The darker oceans absorb energy, which warms the water. Oceans help keep the Earth warm because they absorb a lot of heat (approximately 90%). This warming increases water vapour, which acts as a greenhouse gas and helps to keep temperatures within ranges humans have largely taken for granted for millennia.

Submarines Which Produce Icebergs
Iceberg-making submarine aims to tackle global warming by re-freezing the Arctic
The submarine-like vessel would submerge to collect sea water in a central hexagonal tank. Turbines would then be used to blast the tank with cold air and accelerate the freezing process. During this process, the vessel would return to the surface of the sea and the tank would be covered to protect it from sunlight. A system of reverse osmosis would be used to filter some of the salt from the water in order to speed up the process.
Once the water is frozen, the vessel would submerge again, leaving behind an "ice baby" with a volume of 2,027 cubic-metres. These miniature icebergs would then cluster together in a honeycomb pattern to form a larger ice floe.
