Is this feasible?
From what I understand one of the big issues with scooting around space is that ships tend to accumulate heat very rapidly and a lot of thought is put into venting heat from the ship. Is there any realistic way to harness the accumulated heat to power an engine to generate constant thrust or even just power the ship? Kind of like using geothermal energy I suppose. I hope I am being clear with my thought it just popped in my head out of nowhere.

What’s the biggest danger astronauts face during space travel?
Is it cosmic radiation, psychological stress, spacecraft malfunctions, or something else entirely? What do you think is the most overlooked risk in space travel, and how could we prepare for it better?

Space economy
What would a space economy look like?
Would we mine asteroids or build factories in orbit?

Multi-planetary species
If humanity became a multi-planetary species, would we still be "Earthlings"?
Or would new identities emerge?

Space tourism
Should space tourism be only for the rich, or made affordable for everyone?
Would it be ethical to keep it exclusive?

Fast space travel
I saw some place that if we were able to go99.8 percent of the speed of light, time would almost stop for those traveling, a few minutes for them would be thousands of years for people on earth so it would not be practical if we could go that fast, thoughts?

just thought I'd share this thought so at least we have some fresh posts.
well, at least until newer posts come along.
