I know you're being snarky, but the chemical process for that exists! It's called the Fischer-Tropsch synthesis. You take air, CO2 specifically, and then run the process, which needs electricity, possibly from solar panels, and get diesel/gasoline/jet fuel out the other end! Isn't science amazing?
There are practical issues with it, but it's possible. The question is EROI or Energy Return on Investment. Do you get more energy from it than it took to make it, which unfortunately is not there yet. Shrinking it down to fit into your backyard is an exercise left for the reader.
Hyperspace Pirate tried this at home, and it's horribly inefficient: https://www.youtube.com/watch?v=jRKbjT8AoJw
Fischer-Tropsch uses CO, not CO2. You also need hydrogen. The input is not air but other hydrocarbons. Coal being the most common.
it is more than possible - this is exactly what casey handmer and his startup terraform industries is doing in a pilot plant in the desert: https://blog.terraformindustries.com/2026/10/21/terraform-20...
