The group, made up of a scientist and two engineers, are now looking for investors and are in talks with Toyota and General Motors (GM), as well as governments in a number of countries.
The “Greenbox” captures the global warming gases, which are deposited in a cartridge in the boot of the car. These cartridges need to be changed at regular intervals, up to three times per tank of fuel, depending on the type of car and how it is driven.
“We can’t say how we’re holding the emissions in the cartridges,” says Ian Houston, one of the engineers behind the invention. “But I can tell you that you can carry the cartridges and move them around. They are even safe to take on a flight.”
As compressed gases and any substantial amount of liquids are not allowed to be carried on flights, this may suggest that the emissions are stored in a solid form.
So far the Welshmen have invested £170,000 in the Greenbox’s development, which can also be used on houses, factories, buses and trains.
The Green Box in the video is not the actual size of the unit. It is designed to fit on a small car. The box is over sized to hide the contents.
