Could steel become a carbon sink if we use atmospheric carbon in the smelting?
There are (at least) four potential solutions for air travel: batteries, hydrogen or using fuels synthesized using either atmospheric carbon directly or indirectly via plants. I dislike the massive arable land requirements of bio-fuels, so I hope one of the other three wins. I'd bet on synthetic fuels but all three are fine.
Air travel is at the stage cars were in the 90s. We had prototype EV's and prototype Hydrogen fuel cell vehicles, and didn't know which would win. Both were crazy expensive, and both had too many compromises to seem acceptable.
