Just out of curiosity, has there been much research on alternate fuels for jets? There's been a lot of interest lately in methane powered rockets, which are more efficient than kerosene powered ones, without the difficulties of working with hydrogen. Plus, methane can be generated from atmospheric carbon, making it carbon neutral.
It's unfortunate that there aren't that many other options for intercontinental travel. Battery electric planes are very unlikely to ever be up for the task, and an orbital ring network would require, gasp, a major investment in infrastructure.
