Luxury space hotel?

This sounds fun. It would be nice to have a doughnut-shaped space station that rotates to produce artificial gravity, as has been envisioned for so many years. See:

And a FAST build, only Six years...

Hi AntennaGuy. Wow, this looks like even more fun than the Space Needle in Seattle.

Thanks for this interesting link and article AntennaGuy, and the best of regards.

Very interesting. I've also heard of an inflatable hotel concept, but I haven't seen much about it in the news in recent years. I think the guy behind that concept is Robert Bigelow, a Las Vegas hotelier.

So far, the Space Needle is higher up.

But a man can (and should) dream...

This consept seems to me rather interesting. But there are some scientific problems that are needed to be solved before this project starts building. Also, as for me I don`t see any nessecity of this space hotel. Just imagine how much it would cost to build it. I assume we have more important stuff in space exploration. ( not taking into consideration issues we have on Earth )

In addition to my answer above, I wanna say that I am not the specialist in the area of building such things but still I assume that it`s rather expencive thing to build and as for me it`s completely needless and useless. On the Earth`s orbit we already have a lot of space junk which became the issue for space companies.

Someone will make a lot of money out of it as there is a lot of very rich people around seems this covid thing has made the rich richer and the poor poorer

The question is how they are going to solve artificial gravity issue. The artificial gravity being an essential component of the end-design marketed here, there won't be any significant source of profits prior to its full achievement. This does not work in the Space industry where contingency is inherent to this market.

Hi !
If you compute the acceleration obtained with a rotating wheel, with a radius of 45 meters, and one revolution per minute, a 70 kg people would seems to be a 3,5 kg one …
The hotel must be rock-solid !

They plan for it to be slower than that, and larger than that. They say/plan r = 100m and plan/expect an effective gravity similar to that on the moon. Lunar accel due to gravity is roughly 1.6 m/s^2. Set omega^2 * r = 1.6 m/s^2 and solve for omega = 0.016 /s. The period is 2*pi/omega = about 393 seconds (i.e., about 6.5 minutes for a single full turn).

For a short hotel stay, that should be more than sufficient to allow the guests to get a decent nights' sleep and keep their food down. The more adventurous can experience as much zero-g as they want.

It seems you have omega^2 * r = 1.6 m/s^2 and solve for omega^2 = 0.016 /s, so omega=√(0.016)≈0.13 and 2*pi/omega≈50 s, so less than 1min for a single turn.
Have a good day !

I am still convinced that this is less important stuff to do concerning space exploration department. This department has a lot of stuff that needs to be solved in further possibility discover something new in space. Yes, this is an interesting project to do but lets not forget some more important issues which we still need to solve.

Well, that's embarrassing. I somehow failed to take the square root. You did it correctly. Thank you for pointing out the error and for correcting it.
