What about the process of getting into space? Do you think we will ferry to the upper atmosphere and board another ship? Or will we go from ground to space?
Manouvering it would be a bitch when you get in close to other occupied planets (which would likely, given that they're a spacefaring people with otherworldly contacts, have a 'cloud' of occupied ships and satellites surrounding them). Anything that large going at relativistic speeds is going to have huge issues with space junk, rocks and such.
If I ever happen to be in control of a major scientific research company, i will GIVE you a job, and pay for the required education.

:iia: Patent, profit. In that order.
Eudoxia, you don't actually come up with most of this stuff do you? Don't you just post it from that one website? Maybe you should post a disclaimer so everybody doesn't start thinking you're the next fucking Einstein. I don't mean to sound condescending. I just don't think you'd want credit for something that isn't yours.
it seems to me like a mass diver would be a bit easier to make than a Lofstrom Loop, but that's just me [editline]11:05AM[/editline] [QUOTE=Zombii;21427149]Eudoxia, you don't actually come up with most of this stuff do you?

eudoxia is one smart cookie maybe you should get some university courses down, and work for SpaceX
Well, well, well. Robert Zubrin (1994): [QUOTE]The magsail was invented by Dana Andrews and I working in collaboration. What happened was this; Dana had an idea for a [B]magnetic ramscoop that would gather interplanetary hydrogen and then feed it to a nuclear electric ion drive, thus avoiding the necessity of the p-p fusion reaction in the classic Bussard scoop[/B]. the problem was, according to Dana's rough back of the envelope calculations, he was getting more drag than thrust. Dana asked me to help him on it, hoping that a more expect calculation would give a more favorable result. I wrote a code and modeled the system as a Monte-Carlo problem, and discovered that Dana was wrong: he was not getting more drag than thrust, he was getting MUCH MUCH more drag than thrust. At that point I made the suggestion to Dana that we abandon the ion thruster and just use the collection device as a sail. He agreed. [/QUOTE] :saddowns:
wasn't a ship like this mentioned in an episode of Carl Sagan's Cosmos? (one that gathers hydrogen)
[QUOTE=wonkadonk;21434942]wasn't a ship like this mentioned in an episode of Carl Sagan's Cosmos? (one that gathers hydrogen)[/QUOTE] Yes, it's called a Bussard Fusion Ramjet. Basically, it uses a UV beam to ionize Hydrogen atoms in the Interstellar Medium. Then, a magnetic field picks them up. The field compresses them in a reactor, causing them to undergo nuclear fusion reactions, generating thrust. There are quite a few problems however, but it's still a good concept that deserves close consideration. Here's a cool picture from the Space Traveller's Handbook (I'm waiting for my copy of this one, Amazon ftw :razz: ) [IMG]http://i42.tinypic.com/10shys6.jpg[/IMG]
Just a question, what do you mean by infinite acceleration? Do you mean that it keeps increasing?
[QUOTE=Swebonny;21435420]Just a question, what do you mean by infinite acceleration? Do you mean that it keeps increasing?[/QUOTE] No, the acceleration is constant, but it can accelerate as long as there's Hydrogen in front of the ship (And by default, as long as the reactor lasts lol)
you should compile a list of reading material you recommend for people who want to learn more about this stuff

[QUOTE=Eudoxia;21435468]No, the acceleration is constant, but it can accelerate as long as there's Hydrogen in front of the ship (And by default, as long as the reactor lasts lol)[/QUOTE] Ah ok. I have forgot how it works. If you give something a push in space, it just continues to move into that direction right? With a constant speed, but 0 acceleration?
[QUOTE=Swebonny;21435843]Ah ok. I have forgot how it works. If you give something a push in space, it just continues to move into that direction right? With a constant speed, but 0 acceleration?[/QUOTE] Exactly. With no air to produce friction, mass inertia will carry it forever.
The law of inertia, thanks! Heh, at first I thought that you could keep something constantly accelerating by just giving enough force at start. But obviously that would not work. Your idea is really interesting, although I think lies a few decades into the future. If only there could be more projects like ISS on this planet and more money put into space.
[QUOTE=Eudoxia]lol epic fail[/QUOTE] I'd never tought this same guy would make such informative threads.
Damn Eudoxia, You make the most technilogical threads ever. So full of information and what not.
