Greenbox turns car emissions into bio-oil

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 one. This is then forwarded to huge central processing tanks where algae fixes the carbon dioxide that is extracted from the spent Greenbox, i.e. it grows, to be harvested as biofuel. Great idea, if it works. Who would have predicted that mankind's future could depend on us taking up a new symbiosis with... algae?

clipped from larvatusprodeo.net Three Welsh inventors are touting their Greenbox system that would replace car exhaust systems with an emissions capture system. It uses algae to absorb the emitted gases and hold them inertly so that the boxes can be easily transported for centralised processing of the car wastes. The three [...] have set up a company called Maes Anturio Limited, which translates from Welsh as Field Adventure. Through a chemical reaction, the captured gases from the box would be fed to algae, which would then be crushed to produce a bio-oil. This extract can be converted to produce a biodiesel almost identical to normal diesel. This biodiesel can be fed back into a diesel engine, the emptied Greenbox can be affixed to the car and the cycle can begin again. The process also yields methane gas and fertiliser, both of which can be captured separately. The algae required to capture all of Britain’s auto emissions would take up around 400 hectares.
