The CO2ube by research and development startup Ecoviate is a disposable device that is attached to the end of the exhaust pipe of a car to reduce its carbon dioxide emissions.

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.


The creators of the device are currently seeking approval for users of the CO2ube to be allowed to drive in the high-occupancy vehicle (HOV) lane even without meeting the minimum occupancy requirement. They are also seeking approval for CO2ube users to receive additional tax credit from the EPA

That’s not all. The CO2ube creators are also working on an accompanying app that will provide users with analytics of their carbon dioxide emissions.

Ecoviate’s founders Param Jaggi and Johnny Cohen were both in Forbes 30 Under 30: Energy for 2012 and 2013. The two have studied green technologies since they were twelve. The CO2ube is Ecoviate’s first product.
