Well, you said "commercial" ;-) Commerce needs, imo, an economical basis. I must object the money argument: since ~10 to 15 years money is not a limiting factor any more. The markets are flooded with too much of it, seeking valves like harbours without traffic, unfinished airports, useless borrows under major cities, half baked infrastructure for energy, Hotels without guests, you name it :-) Ability and will to realize and finish limits big projects, not lack of money. But that touches forbidden ground i fear. But ok, waving it all away and looking at the technological and organizational aspects. But aren't we then back to all those more or less reasonable design studies, proposals, artist's impressions of wheels, balls, tubes, lattices, panels, etc. pp. ? Everyone can choose her favourite design from one of many, we can speculate over health, provisioning, safety, collision risk, transport media to and from, which will sooner or later lead us to space elevators and dyson spheres. Isn't there a vacuum without a specific reason ? Wouldn't it be more interesting to have a "commercial" aspect on which to build ? Edit ninja'd :-)

It is already now, or at least very close, even in real time: http://www.realtimerendering.com/

Most interesting. Maybe the Spanish montadito is derivable from that ? Time for lunch !

He had NASA. And that's something different. There was need for a rocket, especially was there need for a capsule to transport humans to the ISS. He first tried to buy Russian hardware for the first steps, that didn't work because too expensive, then he invested some of his own multi billion money and offered his private stuff like plane and soon after the first tests were successful got a multi billion funding from NASA. His rockets do fly and i believe even earn money, if we take the funding for granted. I doubt they can ever pay that back. But i don't see any reason or need for a commercial space station, a tourist every 2 years isn't enough. Ok, i am exaggerating, but not much :-)

Good work, sir ! I see pretty hefty wheel flanges, or have the wheels a small diameter ? Will they run on code 83 (roco line for example) tracks ?

hmm ... do they have one customer who pays 25m$ to rent a yet non existent module ? It has become quiet around them ... after all the announcements. I doubt that there is actual business for them.

Earthly analogies don't work in a deadly environment where one has to bring in every single molecule necessary for upkeep. Earth has infrastructure, atmosphere, gravity, shielding, water and food. Space not. Models and depictions of space stations are available for a cent a dozen, none is realistic (yet ? ever ?). There are more than enough competing opportunities for all types of "commerce" here on earth, where there is air and food and no immanent danger of technical failure. The guys from that "commercial" model (IT, tax exemption, whatever) usually are not the ones who love to live risky ;-) The longer i think about it (30 seconds or so :-)), the more i think that a station for commerce makes no sense. Edit: searching "space station design" just results too much information :-)

San Andrés y Sauces "Holy Andrew and the Willows", non-fictional :-) Nice hikes in the laurel forest. Haven't found the willows yet.

Well, all imaginable designs for space stations and more are around somewhere, my question would be, what kind of "commerce" would the station be good for ? Who would travel to space for an exchange of ideas or to sell and buy things ? I mean: would you set out on the ocean or on an airliner just for "commerce" or rather to travel from a to b ? Sure, you can do commerce in a vessel of any type, but the reason you boarded it was for travelling (or leisure), or not ? But who (apart from the people who build giant yachts to do commerce on them) will go to space for commerce ? And, may i say, it needs more than a crew capsule to build a station of any type. And, if i am not mistaken, such a contraption must be in a high orbit to avoid collisions with the fast growing cloud of things up there.

Don't they use microfiche or so and copy every now and then (between 10 and 50 years, depending on media) ? Or wasn't the data considered as important as other historical data, like in national archives ? --------------- @DDE: I know of no real world iron age naval archaeology on larger ships than the triremes and smaller ones, and a plethora of antique merchant ships from the neolithic to the medieval, which makes for a nice picture through the times and spaces. At least one trireme has been experimentally reconstructed and sailed. While larger ships existed according to the narrations of contemporaries e.g. from the Punic wars, we do not exactly know how they were constructed and rowed, so the number of decks and oarsmen per oar is speculation. Experience shows furthermore that once real world findings emerge somewhere somehow, this frequently relativizes the contemporary writings. I want to say that the stories told and traded may not be correct and archaeologists are usually not the kind of people who live for the "bigger is better" credo :-). But again, i am not an expert in the antique, and modern day archaeology is more about every day life than about warfare. So, i'd have no problem with corrections if they are underlain with sources :-)

Just realized that a Netflix film team arrived on La Palma to film scenes for The Witcher series. Was not aware that a video game could trigger tv series. I just hope i don't run into one of the monsters at night ... https://eltime.es/isla-bonita/20723-dos-semanas-en-la-palma-con-henry-cavill-el-brujo-de-the-witcher-y-el-elenco-de-la-serie-de-netflix.html

Changes nothing, so i can just post it: Ruhr

Yaoundé ... from the mid range backwaters to a capitol city :-) No fox or hare there i'd assume ...

Singhofen An uninteresting place, btw, where fox and hare say good night to each other. Really.

And afaik archaeology has not found remains of such a contraption yet, but i may have missed something because i don't specifically follow this newfangled metal ages stuff. Written history alone is not always a reliable source. -------- It would surely be possible to make the tools and materials to build an Apollo style spaceship, and maybe in 400 years, if all goes well until then, a reenactment group will build such a mission and fly it, listening to silly rock'n roll music, just as some people practice medieval style weekends, listening to pentatonic music out of drone instruments :-)

Not that i knew of. There are limits to what the material can stand (wooden ships of these sizes need to have some calculated flexibility or they break in dynamic waters), the crew can do (difficult to stack more than 3 oarsmen in the available space) how they perform (the length of an oar is limited by the lever necessary to row it in perfect stroke with the others as well as keeping clear from neighbour ships) and to the number of oars per unit of space (immanent interference with the ones above, below and around). Manoeuvrability and stability (centre of gravity) is another thing and sets limits to size as well. That's why i tried to lure you away from speculating about the impractical :-) And an oarsman who touches another while rowing has to pay the evening in the harbour bar, y'know ;-) That's expensive for 170 oarsmen/-women ! :-)

The find situation is sufficient to build replicas of different types of ships from different times and folks, your triremes or warships in general as well as and more so merchant ships from different cultures and times, helping to document trade routes and goods as well as giving insight into technology. Speculating about the imaginable but not reasonable or even doable and above what is known from descriptions and find situations may be nice but doesn't help and blurs the view on reality :-) Which may be an aspect of the OT: technology has advanced. Any blueprints or a replica of a mighty F1 belongs into a museum next to a trireme, if i understand it right today's existing engines and those under development will be better(tm) in terms of efficiency (isp) and usability (throttling) ... but i may be wrong with this.

Enough to have a rough estimate of how, who and where. I spare you all the details in order not to derail :-)

There is only a general answer to this question, as the exact composition of these bodies and their structure is not well known. We have only looked at or scratched the surface. Potentially one could obtain the elements they contain, weighing cost against effort.
