Cleaning oil with magnets

3617

Oil spills are an unavoidable part of our future on this planet. Until we no longer have to rely on the messy stuff, we will still have to pump oil and ship it around the world, and drilling and shipping inevitably means spills. Now, there’s a smart way to remove it. By applying a magnetite dust to the spill. This creates a magnetic field, and the magnetic/oil particles will line up in the direction of the field. The fluid becomes more rigid and then you can pick it up.
