What: "A catalytic converter is like the space/time-ship Tardis from Dr. Who (which looked like a tiny London Police Box on the outside, but was bigger than Parliament House on the inside). A catalytic converter might be smaller than a shoebox, but inside it's bigger than 2 football fields. The core of a catalytic converter is a ceramic oval honeycomb mesh. Because this mesh is pierced with squillions of tiny holes and is coated with alumina, it has a surface area of about 23,000 square metres."
