Polar Shield - this image which looks straight out of a scifi scenario is actually an engineering project to address the increasing loss of polar ice due to global climate change. The arctic skyscraper project combines novel power generation with desalination to protect and restore the polar ice caps, all while housing research teams and eco tourism to further raise visibility of the issue.
Through its desalinization and power facilities, this arctic skyscraper becomes a floating metropolis equipped with […] research laboratories, renewable power stations, dormitory-style housing units, eco-tourist attractions, and ecological habitats for wildlife.
Salt water is used to produce a renewable source of energy through an osmotic (salinity gradient power) power facility housed within the building’s core. In addition, the structure’s immense canopy allows for the reduction of heat gain on the arctic surface while harvesting solar energy.
