The futuristic Arctic Saver Tower—designed by Yiyang Xu and Jingyi Ye of the National Taiwan University of Science and Technology—aims to keep glaciers frozen and prolong winter in the region, thus extending the migration periods for many different animals there. The creation would function both above and below sea level. One unit underneath stores seawater, while two units above “are exposed to cold air during rotation”—a process that would actually take several months. Then a sprinkler on the outer frame sprays this water onto melting glaciers, thickening the ice—ultimately extending the melting time, and giving animals (specifically polar bears) more of a chance.
