Could Carbon Dioxide Be Turned into Jet Fuel?

I'd rather CO2 be turned into a building material... like wood or bricks. That way it's fixated. Sorta defeats the purpose to put it back out into the atmosphere, and why I don't really see today's "carbon capture" stuff going anywhere unless we find a source of "free" energy.

It's called "wood".

Trees are 90-95% air. Carbon, hydrogen, oxygen, nitrogen. Here's Feynman explaining this.[1]

This new fangled technology is incredible. I visited one of these "tree stores" and I do admit the smell of the tree section was quite pleasing.

It depends on your comparison point. If the comparison point is "we're going to fly all these airplanes; with what shall we fuel them?" it makes a lot more sense than if you start with "we have a lot of excess energy and want to remove carbon dioxide from the atmosphere; where shall we put it?"

Ah so what you're saying is it's like flying an airplane with a nuclear plant, but the nuclear plant is on the ground and hooked up to a hydrocarbon plant as an intermediary.
