The hO2+ scraper is an autonomous floating unit of livable, functional and self sustaining space which will function, in a collective manner, as a floating city. It is self sufficient as it generates its own power through wave, wind, current, solar, bio etc. and it generates its own food through farming, aquaculture, hydroponics etc. It carries with its own small forest on top its back and supports places for users to live and works in its depths. Its bioluminescent tentacles provide sea fauna a place to live and congregate while collecting energy through its kinetic movements. Such sustainability strategies aim to ultimately create and provide an oasis with ‘Zero’ negative impacts to the environment, not only that but also improves on it hence the ’Plus’. Aptly as poetic antithesis to a skyscraper which goes up into the heavens the hO2+ scraper goes down to the depths of the sea.
