    Default Hypothetically Speaking

    Hi I am a writer, or so I claim, I want to know how one would go about to create a bioship you can use as much technical terms as possible want what I write to be as authentic as possible. So any help is welcomed, so you might also want to give me books or publications I can refer to?

    Do you mean a ship that is alive? Some sort of geneticly engeneered critter? Do you mean a ship built by animals like a giant termite mound? Do you mean a multi generation ship like in "Rendezvoux With Rama" with thousands of crew? Or my own multi generation ship design that is much smaller with only a couple of dozen crew that uses mind transfer and cloned astonauts to refresh the crew?

    You are the writer. Then you can dig deep into your imagination and paint a story line ship in your mind.

    A self sustaining bioship crossing the galaxy with hydroponics and lamps and humidifiers and..... imagination can work wonders.

    In the real world it has not worked so well.. The bio-sphere program. I think it failed... ?

    What is a bio ship?

    I am glad that you want to write something that is at least close to real science. A lot of recent science fiction like the recent »Startrek«, zombie-related stuff is just pure liberal ivy-league effluent. So congrats and cheers!

    You probably want to hang around some scientists. Go to university colloquia and just listen. Go to astronomy clubs and listen. Ask questions and listen to the answers. That should get you started.

    Also go check out university libraries and bookstores.

    Excellent question! I'm not sure who posited the idea of a bio ship first, but I know Heinlein incorporated a hydroponics farm into the training ship for his 1948 novel, "Space Cadet."

    One of the more recent biosphere-related enterprises these days is the field of "aquaponics." Put simply, these backyard mini-biospheres combine green-house hydroponics with fish farming. The plants and algae feed the fish, and the fish by-products, sun, and water provide nutrients for the plants. Obviously, both the plants and the fish feed the humans who tend these systems. If you're good with basic tools and gardening, you can design and build your own for less than $1,000. I knew one guy who spent less than $300 for a 10'x12' unit.

    The Wikipedia link I provided above has all the info you should need to incorporate the technology into your story. For zero-g environments, I suggest you spin that section, if not the entire habitat, as both plants and animals do better under 1 g than in zero-g. The plants could care less about the spin, but spins faster than 3 rpm prove problematic to both humans and fish. One RPM is the fastest spin rate where experiments in the 1970s showed no detrimental effects. Anything faster and the effects started appearing, so you'll need a large wheel and spoke setup for long-term travel. I'll leave it to you to figure out the physics so you'll know how large the habitat wheel needs to be for your novel. Also, if you need that much habitat room, try a pod and pendulum (counterweight), connected via a long line. Even a small counterweight can spin a large pod, given enough line between them.

    I think he means biosphere. The term was coined when a scientist talked about earth as a ship with limited resources.

    I love it (NOT) when people waltz onto a forum, contribute absolutely nothing, ask a question, get handed some great ideas that took a decent amount of time to produce, then waltz away without so much as a "thank you."

    Here's a book for you, Barry: Everyday Etiquette: How to Navigate 101 Common and Uncommon Social Situations. Link.

    I'd suggest you read Arthur C. Clark's "Rendezvous with Rama". Mr. Clark thought of a variety of things that may serve your needs. Rama is a cylindrical ship that has a sea in the middle of it. The author goes so far as to describe why the sea has slosh plates and the wall on one side being higher than the other to account for acceleration. I hope this helps you - it is certainly a good start

    Interestingly enough, any structure such as a long tube, where the moment of inertia about it's longitudinal axis is exceeded by that about any other axis will no longer be stable under rotation. For a rigid body such as a thick steel tube, it will take many rotations for the object to shift its axis of rotation. But for a less rigid object, such as a cardboard tube or a Rama-like tube with movable water and air that's both compressible and movable, it will take far fewer rotations. While slosh plates will help reduce this problem, they will not eliminate it.

    However, actively shifting water around via pumps is a viable means of restoring the proper axis of rotation. If the pumps are solar-powered, it would be far cheaper than expending reaction mass via externally-mounted rockets.
