I talked about ferrofluids soaps that was researched at the University of Bristol and how they could be used for oil spills and the like. These researchers at MIT tried it out. They used magnets really, really tiny magnets to transform oil like oil polluting the Gulf of Mexico into trapping it with a ferrofluid that can be manipulated. This could separate the oil from the water then could be recycled and the oil stored. Simple? Well it sounds simple but that is why they are still researching it.
