These structures look like giant robot jellyfish, but they could one day function as eco-friendly hotel lodges. Conceived by Janine Hung, a graduate architect based in the Philippines, the floating lodges boast kitchen and bathroom-equipped living quarters and gardens in their underbelly that can raise fish and grow vegetables. Beneath the surface, the solar-powered structure has'tentacles' which capture and collect rubbish, and filter polluted water - either storing it for human use or returning it to its source clean. Ms Hung, who designed it for Inhabitat's Biodesign Competition this year, received an honorable mention for her innovative creation. 'The Jellyfish Lodge proposes to rehabilitate the world's most polluted river slums by removing waste, treating water, growing food, and purifying air all through solar power,' judges stated.
