Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
I can see how it could work. But we would first need to have so much spare clean energy that we can afford to use some like that. And we are some way from being 100% zero emissions, with time running out.

So I would imagine that, before we can use our renewables to make fuel, there is a period when air travel really has to shrink massively. It uses a LOT of energy.
Although maybe it's more realistic to imagine that, since air travel would tend to be something the rich demand, it will stay strong even at the cost of a major catastrophe. But I was putting myself in the scenario of a clean society in the near future, which kind of eliminates such considerations.

Earth provides enough to satisfy every man's need, but not every man's greed. Gandhi
