If you're catching the products of your exhaust then you're now negating the effect of producing the exhaust in the first place, so you're not going anywhere.
Yes Newton's 3rd law. Inconvenient. AI tells me we need better Closed-Cycle Engines.
It's very hot vapour coming out the back, but I guess it is freezing pretty quick and creating a cloud of some kind. Nebulas seem to stay in the same place. And we could model where this gas is most likely to be. Maybe by trailing a massive charged (sticky) net of some kind we could fish some water back in.
Not all rockets produce water. Rockets that use hydrogen and oxygen do, but not all rockets use that fuel blend.
My one does. 8) I'm guessing a generation ship is running on momentum most of the time.
Frozen water does not have most of the things to sustain life. It has water, which is a component required for life as we know it, but that's only one component.
Yes, most was a poor choice of words. More accurate we cant live without it. Wonderful thing about water is it's utility, I can drink it, break it down into H2 and O for fuel and O to breathe. Why we are so keen to find it. I fully expect you know that
Thank you for exploring the idea with me, a pleasant distraction from the work I should be doing.
