I am currently developing an underwater breathing apparatus that will allow humans to explore the depths of the oceans. This invention consists of a watertight mask connected to an air supply system. With this device, humans can spend extended periods underwater, unlocking new possibilities in scientific research, transportation, and resource extraction. This will lead to a better understanding of marine ecosystems, facilitate safer trade routes, and potentially discover untapped resources to improve the quality of life back on land.
