Would it be erreneous to say that no matter how 'green' our industries and power consumption on ground becomes, aviation and space flight would always require carbon based fuel?
- pilsetnieks 10y agoAn electric plane could be a possibility, depending on advancements in battery technology or power storage in general. Space flight would most likely require some kind fuel, at least in our lifetimes - so far we haven't found any other way to move mass in vacuum other than expelling propellant. However, not all rocket fuel/propellant is carbon based, in fact, most aren't.
- mathw 10y agoWe may be able to develop better electricity storage to allow electric planes to be more practical than they currently are. However, there's also a lot of interest in using biofuels for aviation, so you may see that in the mid-term future we're using carbon-based fuels but they're largely carbon-neutral.
- Symmetry 10y agoIf we can make renewable energy cheap enough it'll start making economic sense to synthesize fuel oil out of the air and water rather than mining it out of the ground, leading to no net carbon consumption.
