Three fishermen from Wales have invented a box that can be fixed to the exhaust outlet of any vehicle and safely capture greenhouse gas emissions.

However, in addition to reducing the vehicle emissions by 85% to 95%, the Greenbox goes one step further by providing the raw ingredients for new biofuel production. Once full, the Greenbox can be detached from the vehicle and sent to a bioreactor where it provides food to algae that can then be converted to bio-diesel.

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 fertilizer, both of which can be captured separately. The algae required to capture all of Britain's auto emissions would take up around 1,000 acres

Although there are no immediate plans for production, the product has gained the attention of UK Labour MP David Hansen, and Toyota and GM have reportedly spoken to the inventors. Facilities and infrastructure are obviously lacking for both the mass production of the Greenbox and the associated biofuel production chain. However, at the bare minimum the announcement shows the sort of ecological and self sustaining solutions that are waiting to be discovered. Time will tell if it becomes economically viable.
