Apparently, you can literally see garbage in the oceans from space. Currents carry them and they cluster at certain points and have begun forming large masses the size of cities. No one seems to be bothered about cleaning these out because it would entail massive expenditures. Luckily that doesn’t stop us concept designers. Designers Song Shi and Liu Kuan developed a futuristic Ocean purifying drone that uses the ocean’s hydel power to purify the water nearby. Its design makes it look like a fan on the water surface, and it has the ability to fold up, allowing ships to position and re-position them at will. Neat! (The oceans too!) Designers: Song Shi & Liu Kuan.
