Convert Carbon Dioxide into Oxygen

My idea is to make a device that converts carbon dioxide into oxygen. It could be like an air purifying device that is placed inside the exhaust pipes in cars, thus stopping emissions before they are even a problem. Now I have no idea how to make something like this or if it is even possible but if there is someone who would know and that would like to help make this idea a product.

Parking Lot Power Grid

Imagine all those thousands of cars parked for hours in a shopping mall with unused electricity stored in their batteries.

Each car could donate up to 50% of its battery level in exchange for free parking and help recover the parking lot’s usage of electricity. Or for huge parking facilities, cars could be attached to a power grid to power community needs and to offset carbon emissions while vehicles are not in use.

It only takes a few minutes to recharge the battery of a car while driving, then it’s ready again to donate the next time it parks.
