You conveniently forgot about climate change.
It also very much matters that my grandchildren will be able to breath, will have food to eat, won’t have to live underwater and won’t depend on wars in faraway lands.
- triceratops 6mo agoIf we can synthesize jet fuel cheaply with renewable electricity it's carbon neutral.
- testing22321 6mo agoYou honestly think “If we can just invent a magic solution cheaply we can keep burning stuff” Is the answer?
- triceratops 6mo agoThe problem with "burning stuff" is twofold: 1. Carbon emissions - not a problem if you synthesize the jet fuel out of carbon dioxide in the air. https://www.climatechangenews.com/2025/06/18/e-saf-jet-fuel-for-aviation/ https://www.climatechangenews.com/2025/06/18/e-saf-jet-fuel-... it's expensive today but with cheap-enough energy, such as with abundant solar and wind power, it won't always be. 2. Air quality - If energy is so cheap that you can literally make jet fuel, it follows that we'd stop "burning stuff" for any other reason. No more coal or natural gas plants, gasoline or diesel engines, heating with natural gas or propane. Jet planes' air pollution is a tiny fraction of all those sources. I could live with that.
- nradov 6mo agoYes, that's the answer. If we want to have long range air transport then we're going to keep burning stuff no matter what.
