The futuristic "Heal-Berg" skyscraper could be the next generation of sustainable building. The design for a iceberg-shaped floating skyscraper will heal the planet by zapping carbon dioxide and transforming it into fresh air. Created by Luca Beltrame from Italy and Saba Nabavi Tafreshi from Iran, the promising design earned an honorable mention in Evolo's 2017 Skyscraper Competition.

The inventors wrote in their submission: "Our vision for HEAL-BERG is to create independent complexes (in terms of energy and mobility), designed to cease, heal and reverse the process of climate change and its impacts on the earth. We went on a mission to collect some of the most recent innovative technology breakthroughs from all around the world, and combine them as elements of a greater embodiment operating as a whole to achieve a goal, survival."
