Exhaust-Filtering Tube Reduces Car’s CO2 Emissions
CO2ube is attached to the end of an exhaust pipe to filter out the carbon dioxide.
According to its Kickstarter page, the device uses algae photosynthesis and basic chemical processes to reduce the carbon dioxide from the source, which in this case is the exhaust of a motor vehicle. The creators of CO2ube used a proprietary method to grow a type of algae that can withstand the environment of an exhaust system. They also included a secondary reactant to further reduce the carbon emissions. Because of its consumable nature and engineering, the filter is expected to last for eight to ten weeks.
