Carbon dioxide engine emissions are diverted into a Greenbox, which is about the size of, and replaces, the car exhaust system. This Greenbox traps the exhaust carbon-dioxide and holds it inert. It is big enough to capture most of the carbon dioxide emissions from a full tank of fuel. using the carbon dioxide as fuel. When a new tank of fuel is filled, a fresh Greenbox is swapped with the spent
