BACKGROUND OF THE INVENTION

Field of the Invention

The present invention generally relates to vehicle tail pipe filter, and more specifically to vehicle tail pipe filters for capture of greenhouse gas emissions.

Description of the Related Art

Light-duty gasoline powered vehicles have been deployed everywhere for people to travel day by day to: complete their chores, get to and from work, and engage in personal activities. It has greatly enabled individual productivity from when the idea was first patented in 1886. This activity has also created a consequence of emitting greenhouse gases into Earth's atmosphere. Now, it is 2021 and our world is resolving what has become the climate crisis, where we have come together to reduce individual, corporate, and governmental greenhouse gas emissions to zero. Civilization has been able to thus far properly address reductions of greenhouse gas emissions from the production of: electricity, chemical reactions to produce goods from raw materials, energy, businesses and homes, maintenance of livestock, and usage of cars, trucks, planes, trains and ships. While our world has actively engaged itself to reduce emissions in all of these sectors through electrification, there seems to be one vital sector that is being left behind: further reduction of emissions from existing gasoline engaged light-duty vehicles.

The light-duty vehicle industry has actively sought to reduce its greenhouse gas emissions for decades. Research and development investments have gone into making an Earth friendly light-duty vehicle, such as improving the catalytic converter, replacing the internal combustion engine system with an electric system, or adding an electric based engine to the gasoline powered vehicle propulsion process. Gasoline-powered vehicles still produce significant emissions; and even if a more efficient catalytic converter or energy reducing engine system is created or improved, it won't be affordable to most people that currently own and operate a functioning gasoline powered vehicle, especially in regions where electric vehicle adoption rates are concerningly underwhelming.

As the vastly anticipated electrification of the light-duty vehicle industry is under way, major car companies have committed hundreds of billions of dollars thus far to electrify the world vehicle fleet. Currently, an estimated 1.2 billion cars on our roads are powered by fossil fuels. It is disastrously anticipated that still, new models in future years will still consume fossil fuels and produce greenhouse gas emissions.

Onboard carbon capture technology has become feasible for large internal combustion engines in industries such as maritime transport and heavy duty trucking. Attempts to capture carbon dioxide from the tailpipes of light-duty vehicles have been attempted before, but onboard conversion caused the entire process to be environmentally uneconomical. By capturing emissions and converting the emissions using a conversion device unattached to the light duty vehicle, the environmental economics become feasible.
