The Oil Cleaning Guard is designed to contain and prevent the spread of oil while simultaneously cleaning it up. It even signals avians and fish to stay away with a series of light beams. Although it’s not very clear on how it works, the designers say the system performs a filtration process onsite by separating the oil from the water.

Oil Cleaning Guard has won the Lotus Prize this year.
