With rising sea levels due to changes in climate threatening the coastal cities worldwide, the need for floating or underwater cities and architectures has been felt more than ever before. Conceived by Malaysian designer Sarly Adre Bin Sarkum, the “Water-Scraper” is a self-sufficient underwater architecture that employs a variety of sustainable technologies to produce renewable energy and grow its own food. Fulfilling its energy requirements by harvesting wave, wind and solar power, the floating city makes use of modern techniques of farming, including aquaculture and hydroponic methods, to grow its own food underwater. While a system of ballasts, supported by a set of squid-like tentacles that generate kinetic energy, keeps the structure steady in an upright position. Considering the fact that 71% of the Earth’s surface is covered with water, which is likely to increase due to the environmental changes in future, the underwater skyscrapers or cities provide a ray of hope to sustain life on earth.
