To be fair, carbon capture for night time energy usage is a plausible path for us to solve the mismatch between when we use energy and when solar produces it. If we go that route as a society, turning a tiny percentage of that into rocket fuel is NBD, and probably better than burning kerosene which we currently cannot make via carbon capture.
- immmmmm 5y agoi don't know any carbon capture technology that can be scaled sufficiently, in the proper time scales, that can do that in a way that is quick enough to do any significant dent to global warming.
- ashtonkem 5y agoNo single tech is gonna be the solution here. It’s going to a mix of lowered consumption, more efficient tech, time shifting of demand (EVs selectively charging based on the sun), and a wide variety of energy storage tech. Carbon capture is attractive because it can be used in places where energy density is a critical factor.
- immmmmm 5y agoyes lower consumption plus stuff. where does space tourism fits in the lower consumption scheme? i just don't get it. what is critical? for instance is food production (that will sharply decrease due to climate change) more critical than individual cars, for instance? you also still don't answer the primary question i have as an engineer and physicist: which CC tech is gonna work/can be scaled?
- ashtonkem 5y agoSpace Tourism absolutely doesn’t fit, and if you scroll up you’ll notice that I’m extremely negative on it.
