I wonder what a YC application with such an idea might look like. Design the plane and the fuel containment/loading systems at 2 airports. Start America's first "carbon free" aviation route. Maybe move freight instead of people at first for an easier regulatory pipeline. It's absolutely crazy and would almost certainly fail but so are most of the revolutionary startup ideas that deal with earth heating in any meaningful way.

We can basically have "carbon free" aviation today if we want it by manufacturing synthetic liquid hydrocarbon fuels using renewable power. The US military has already run successful experiments. It works fine, it's just more expensive than burning fossil fuels.
