I figured out what this comunity has been missing, unsubstasiated speculation of thing we cannot begin to understand, so to try to bring some sainity lets talk about what runns FS ships, heavy hydrogen cold fusion reactors. do you think it works do you think the terrans could have come up with something better, what do the shivans use.

Cold fusion is a myth. they use thermonuclear fusion reactors for power and so do the shivans.

I destinctly remember them saying that the ships use Deuterium (aka heavy hydrogen) for cold fusion.
and I would think that the shivans would use something better, like subspace tap drives.

Subspace tap? Like the Vorlon-style hyperspace tap?
Who knows, antimatter? Controlled singularity?
But I do believe the Terrans use cold fusion. It's very efficient, and fits in well with their overall tech level.

I'd say that antimatter is a good candidate for a power supply, lots of bang for your buck. Magnetic field mechanics should be advanced enough by then to handle antimatter. I read somewhere that they recond that a thimblefull of antimatter would have the same "whack" as a 20K ton nuclear warhead. You have to ask yourself though, what idiot do they get to hold the thimble (http://dynamic.gamespy.com/~freespace/ubb/noncgi/smile.gif)
On a similar theme I think there are other possibilities for mega nasty powerful weapons. I once read an Arthur C. Clarke book that had an interesting idea for a weapon, it was a massive rail cannon that fired superheated molten heavymetals at the target making quite a mess of the hull.
That's gonna give you quite a nasty burn (http://dynamic.gamespy.com/~freespace/ubb/noncgi/biggrin.gif)
-
Yeah, but gas miners are for the fusion drives of the fleet, remember? It would follow that the powerplants are most likely fusion as well.
-
On a similar note, in the .tbl files, what is the significance of Max. Power output?
It's most likely Thermonuclear reactors, since no mention is ever made of cold Fusion, and a "reactor core breach" would most likely result from heavy damage(Love the treason.....)

True. Fusion reactors don't explode. If a fusion reactor gets unstable the fusion reaction simply stops.
-
Its the fission dealie stuffs that explode right?
Shivans seem to have the same sort of power systems as Terran/Vasudan counterparts, except for a huge increase in efficiency and power output.
-
Actually, it depends what happens.......fission reactors shouldn't explode (see chernobyl) but fusion reactors, depending of the technology, could very well go up. Because if you breach the magnetic containment fields, all of a sudden this ultrahot plasma at god knows what pressure suddenly can get out....
boom
-
Yea, but with cold Fusion, there's no superhot plasma, hence no explosions.

Subspace Tap? Sounds like what I was thinking earlier...like using a mini-subspace gate to let high-energy subspacial particles flow into the normal universe, and either blow them up as fuel or shoot them straight out the back. (http://dynamic.gamespy.com/~freespace/ubb/noncgi/biggrin.gif)

Shivan vessels that use shield systems require fusion based technologies to power their vessels since sub-space taps interfere with shield matrices.
We know for a fact that the Lucfier was powered by five fusion reactors that have a power output equivalent to dozens of Meson warheads.
The Lucifer, and Shivan fightercraft have fusion based drive systems thousand-fold more in efficientcy than allied systems.
However, they still require deuterium to field these craft.
Most Shivan capital ships are powered by sub-space tap systems, thus their high amount of firepower and manuverability capacity for their size class.
Some recent Terran modifications on the Faustus use a similar sub-space tap.
The alliance makes little use of anti-matter or relativistic technologies.
Namely rail weapons proved ineffective against later designs of the great war when centrifuge technologies were rendered obsolete.
Anti-matter weapons and reactors require a great deal of power to maintain containment, and are also rarely used save for weaponry or powering weaponry. (The Colossus may have used secondary anti-matter reactors for it's main cannons)

Now, I think it's time for me to put in my knowledge. I have done quite a bit of research into Fusion, as it interests me quite a lot.
First off, the difference between cold and hot fusion. Hot Fusion attempts to emulate the chemical process occuring in the sun by heating hydrogen (i'm pretty sure) up to super-hot temperatures, where they shed their electrons and become plasma. These reactors need Deutarium as far as I can remember, and if one of these reactors are breached, the results could be superhot plasma spraying around in the power compartment.
Cold fusion is no myth, it is real and it has already succeeded in passing the break even point in energy creation (produces more energy than it takes to maintain)- something that the Hot Fusion project has not yet managed, despite millions of pounds being spent on it.
Cold fusion takes place at room temperature, and uses metals specially "loaded" with certain elements, and in a electro-chemical reaction produces energy. In fact, it has been suggested that in some variants of cold fusion, the process can be used to dispose of radioactive waste (although what type escapes me).
The greater portion of the scientific community denies cold fusion exists, even though it has been proven to do so. People have different reasons for this, but one of the greatest is probably that they are unhappy that two scientists working on a low budget managed to do something that scientists on a multi-million pound budget had dismissed as impossible.
I personally think the ships in FS2 use Hot Fusion reactors, due to their use of Deuterium.
Interesting facts about fusion:
According to einsteins formulae, E=MC2, a 1 gram raison has more power inherent in it that 20,000 tons of TNT.
Using fusion, a glass full of water can produce the same amount of power as 100 tons of coal, without half the pollution.#
Fusion is the process of two seperate atoms joining to produce energy, fission is basically them splitting apart. Fission is a chain reaction (thus nukes) while Fusion isn't (as far as I know).
And for anyone who disputes these facts, please do research before you argue, do not let your own opinion taint your viewpoint.
IMO, fusion is Humanities best hope for clean energy (but not to say the only one).
-
The Claw: Spaceborne Chicken maniac and nuclear specialist. I'm impressed (http://dynamic.gamespy.com/~freespace/ubb/noncgi/smile.gif)
-
Except that cold fusion has yet to be proved to any reputable source, and repeated attempts to recreate the conditions that supposedly gave rise to it have failed.
As for hot fusion, the best bet is probably deuterium-helium3 fusion, which is fairly efficient and emits only charged particles.
Oh, and a slight correction. Fusion is not a chemical process. It is atomic.
-
Yeah. IIRC, fusion, if you want a He3 atom, needs a deuterium and a hydrogen atom. If you join two deuterium atoms, it makes He4.
Cold fusion I don't really know anything about.
Deuterium = hydrogen with 1 neutron (H2)
-
You will always need deuterium for fusion reactions because helium atoms have neutrons and hydrogen atoms don't.
And Shrike is right, for some strange reason cold fusion only worked when no one was there to see it, but didn't when anyone else tried to do what they did.
-
Quite right, shrike, fusion isn't a chemical reaction, cause it's a atomic one (nuclear reaction... fission and fusion (http://dynamic.gamespy.com/~freespace/ubb/noncgi/smile.gif))
Like I said, before you actually say stuff about Cold Fusion, please do a bit of research...
Like I said, the majority of the scientific community denies cold fusion exists, because it doesn't comply with the current laws of physics (and don't mistake current with "correct"- the laws of physics have been rewritten many times before, and they will continue to be rewritten).
This means you get an overwhelming number of people saying it's impossible compared to a few who say it is... The thing is I am not 100% sure it is true, as it is impossible to find an unbiased site on the net. I did, however, find this: http://www.mv.com/ipusers/zeropoint/IEHTML/FEATURE/cover/32/fset.html ("http://www.mv.com/ipusers/zeropoint/IEHTML/FEATURE/cover/32/fset.html")

i read somewhere that Cold Fusion is totally possible, but that there currently is no power source that generates enough juice to start the reaction...
------------------
Temporal Mechanics ("http://www.fs2temp-mech.co.uk")
-
No, only needs a very small charge. I was just readin a bit more about it, and apparently one reaction managed, with just a fraction of a watt running through the system, to produce 400-500 watts power output.
I was just womdering how they'd harness this energy tho... I know cold fusion gives off it's energy as heat, so I suppose It could well just be the classical nuclear power generator without the fission reactor.
Apparently Hot Fusion gives of it's energy in the form of ionising radiation waves... how the hell are you meant to turn that to electricity?

Nein. Deuterium is used in modern experiments because the energy threshold to get a deuterium-based reaction going is significantly lower than the proton-proton chain that powers main sequence stars. (4H1 -> 1He4 + E) Dammit I need subscripts.
You can pretty much any two+ atoms to fuse, given the right combinations of heat and presure.

See my post above. You can fuse anything you damn well please, it's the ease as which D2 fusion occurs relative to the more efficient P-P reaction. Also, there are other factors that make pure Deuterium fusion less than totally ideal, such as neutron emissions.
-
I know man, I meant you don't need it for Cold Fusion (http://dynamic.gamespy.com/~freespace/ubb/noncgi/smile.gif) (and if you don't believe me, check out the link above and go to the Cold Fusion FAQ (http://dynamic.gamespy.com/~freespace/ubb/noncgi/tongue.gif))

Nah, cold fusion is obsolete...
The real stuff is on zecton accumulators. These things can practically generate any kind of energy radiation out of nothing, and incredible rates. Too bad it's just a concept I've created for an old game idea of mine, PFDS Prometheus.
-
Zero-Point energy, anyone? (http://dynamic.gamespy.com/~freespace/ubb/noncgi/tongue.gif)
-
DOE laboratories should be compelled to work under the direction of those who have
achieved significant positive results, such that there can be no doubt in anyone's mind about these phenomena.
This is NOT science. Ideally, there should be groups who have previously achieved it and those who haven't, but forcing such artificial rules upon ALL scientific research is conterproductive. Science cannot prove something, it can can only disprove something. Forcing all experiments to be done by those who have a vested interest in having it suceed is grossly unfair to the scientific community as a whole.

I agree, and it was only because of "selected" experiments with deliberate mistakes that caused the existance of cold fusion to be denied.

Last I checked, cold fusion was impossible- the only experiment I know about was proved to be wrong immediately. The only reason it got as far as it did was because the people who made the "discovery" (through lab error) reported it to the mainstream press WITHOUT submitting it for review by other scientists.
Nobody else has been able to duplicate their results, so it stands to reason that unless there is some major conspiracy, cold fusion doesn't exist.
And what is really more likely- that cold fusion, unlikely to begin with, is being denied solely out of scientific spite or that it never happened to begin with?

Read above, in one of the links. Many places have SUCCESSFULLY created a Cold Fusion experiment, including Los Alamos.
I just wish people would open their eyes and ears, and take in all the facts... hell, just read the whole page, before they post like that.
If I am wrong, I am wrong. But that many places, reputable places, where the experiment has been successfully carried out, there must be something in the argument.
-
Can't remember what new stuff has been done in the field of zero point energy. I saw an excellent documentary on it but as always the sceptisisim drowned out any possible hype that may have allowed a more indepth analysis. Two macines where shown that supposedly tapped zero point energy but "experts" claimed the results were either nonconclusive or totally wrong (they didn't bother to make their own measurements).
I get the basic theory though and it looks interesting to say the least. By the way, if there are any sites on this put up a link.

Yes, but there also many places, doing the exact same experiments that haven't got positive results.
-

Thats exactly right. Until the people have claimed to make cold fusion work can show other people how to make it work in exactly the same way it just isn't real for any practical purpose. Experiments that can't be duplicated are of no use to anybody.
On a different note, it isn't quite true that you can fuse anything you want to. Fusion only works as an energy source in stars until the core gets to the point where it's trying to fuse Iron. Once it gets the this point it takes more energy to fuse the iron atoms than you get back when they fuse, and this is what causes most stars to die out. Atoms of higher atomic weight than iron aren't capable of being made by the normal fusion reactions that occur in a star. Instead they are formed by lighter atoms being violently smashed together during stellar collapses, especially supernovae (Capella anyone). So although it is true that you can make anything fuse, given high enough pressure and temperature, past a certain point you're losing most of the energy it takes to do it.
-
I never said you'd want to fuse most elements....after about boron or so you start to get vastly decreasing amounts of energy per nucleon. Really, straight hydrogen fusion is the best one, you get the most energy/mass of reactant.
-
i reckon the shivans would use a zero-point field or antimatter.
-
encase that needs an explanation.
a standard nuclear reaction results in a 7-8& conversion of mass to energy i think.
antimatter is 100% conversion, since they annihalate each other.
a zero point field doesnt even need any fuel to start with. In a total vacuum, quantum uncertainty predicts that particle/antiparticle pairs wil flash into and out of existance, and that in either an intense gravity field (around a SMALL black hole..that has a steeper gravity well) or between two smooth peices of mass set exactly one wavelength apart, some of these pairs may become split up and one will "die" (collide with the mass or fall down into the gravity well) and the other may escape.
this also causes the black hole to evaporate, in the case of the gravity well model, or in the case of a generator it will cause an energy flash in the mass.
and the kayser supposedly uses a ZP field so i dont see why the shivans wouldnt use such an obviously superior energy source as their main power supply
-
I've already posted a link, Maeglamor, but if u can't be bothered to go back, have another one (http://dynamic.gamespy.com/~freespace/ubb/noncgi/smile.gif)
http://www.mv.com/ipusers/zeropoint/ ("http://www.mv.com/ipusers/zeropoint/")
Now, just because some experiments DON'T get it to succede doesn't mean it's a viable source of energy. I could easilly make a experiment involving a lightbulb not work, but that doesn't mean that lightbulbs dont.
The explanation on the site above about why others havn't been able to reproduce it is that the "loading" process of the metals needed is extremely delicate, and can sometimes leave cracks in the metal leaving it unviable. I am sure that if they repeated the experiment, and gave it a fair test it would work...
And I'll also be willing to bet these experiments were run by people who are somehow connected to the Hot Fusion project, and don't want to see there "hard earned" funding go down the drain just because someone else has come up with a more viable and economical power source.

fission reactions can start with 1 atom releases an extra neutron and starts a cascading chain reaction and bang - however in reality 1 atom isn't enough - infact there is something called spontaneous fission which at first it hought should have stockpiles of uranium and plutonium blowing up left right and center becasue of the cahin reaction is should create but as i understand it that would only be the case if the nuclear fuels were 100% totally pure other tiny amounts of other elements sever to obsord the neutrons and hence stop an imediate chain reaction and the energy conversion rate isn't anything like 7% its tiny i'm sure - however antimatter is indeed 100%
cold fusion - well the claw i believe it explaind it earlier and he said chemical - and thats the key word in cold fusion - its misslabled - it isn't fusion at all its a chemical reaction - and those that have reproduced the effect probally did but the claim that it was fusion was destroyed when done under proper condistions
fusion the last best hope of mankind at least for cheap energy anyway - the reaction once started will tend to finish the job but the starting point is a far highter energy state - but once afew of the atoms have gone through fusions that alone should produce enough heat to set the others off but its basically done to pressure and temperature whether it will or not - most thermonuclear weapons use a fission bomb to set of the fusions reactions which can then be used to set off another fission layer which sets off another fusions layer etc etcet c - i dont believe there is alimit to how many times you can do this so really you can make a bomb as big as you want with this systme - i believe its called layer cakes or something like that
zero point energy well we knwo there is S**T loads of energy available there but have no idea how to access it
now as to reactors blowing up fusion reactors can indeed blow up - however they will probally only vaporise the reactor and if its a big one the building its in - cause the palsma will cool down fast and its not kept huge pressures thats why the temperature has to be higher in the core of a reacotr than it does in the core of a star - but if it did go off - it would realloy be a huge disater - so the little plasma in the reactor (there is never very much of the stuff) would melt the reactor perhaps abit more - now a fission reactor has the potentil to spew radioacticv dust around aka chernobymle how ever its spelt - however the reactor if seriorsly goes wrong it does have th potential to create a stonking great big bang like a nuke bomb cause if the cahin reaction goes out of control and the reactor shut off the the carbon rods inserted then everything clsoe by will disapear pretty quick
but to my main point or what was supposet to be my main point when i started again - cold fusion is fake - it breaks the laws of physics and not ones were are even unsure about ones pretty much clad in iron hell lets make it titainium

the harbinger descripition is the only thing that wasn't made up for fs1. a modern day fusion bomb uses multiple smaller fission bombs to to set of the fusion bomb, since we dont have anything bomb sized to create the pressure and temp needed to acheieve fusion. the real power comes from the uncontrolled fusion reaction.
the salted part is the real nice part. salted mean the bomb has cobalt added to it to make the fallout worse than it already is. concievably, 1 salted nuke could wipe out all life on earth just from the fallout.

doomsday weapons are indeed poweful but i dont think the are that bad - but certainly one or two could render an entire continent lifeless except cockroaches for 100,000 or so years - and very little is needed to stopa reactor from becoming a rapidly expanding ball of gas - ina fission core - not enough control rods - carbon/garphite rods that are inseted with the nuclear fuel to assumb some of the neutrons and preventing a a runaway reaction - ina fusion reactor - failure of the magnetic containment fields would destroy something like a fighters but the explosions wouldn't be as big since only th fuel in the reactor is going to fuse - once the field is breaches the gas would rapid;ly cool down and would set off the fuel but would not acually fuse it just set it alight- in space it would jsut boil off

Hmmm... it's a debabtable point. The scientists don't seem to think Cold Fusion is chemical, but it doesn't fit in with the modern day physics, so...
It is always worth bearing in mind, though, that some of those laws of physics may be wrong, it's mostly theoretical...
Hmmmm. Fallout. Good game (http://dynamic.gamespy.com/~freespace/ubb/noncgi/wink.gif)
-
I for one don't really understand how cold fusion could work.
I mean, fusion occurs when two atomic cores are given enough energy to overcome the atomic rejective force (or something, my translations aren't always too good) so they fuse into a larger atom. Energy = momentum = heat. So how can you fuse atoms at room temperature?
Hmm.. strong nuclear force is what binds the core together. The electric repulsion is what keeps the cores apart.
Hmm... this can't be right. My book says light cores need at least 1.6e-13 J energy. Well, suppose it's right, and the 10e8 K temperature needed to fuse hydrogen is also right. The bloody hot plasma is hard to keep away from the reactor walls. The Tokamak system works with a magnetic field in a donut.
Now I'm just rambling again. I get that way when physics are mentioned (http://dynamic.gamespy.com/~freespace/ubb/noncgi/biggrin.gif)
-
Energy is given off when two molecules form a bond, thus forming a larger molecule.
Cold Fusion gives off large amounts of heat, depending on the experiment. However most seem to indicate it is past the break even point.
I'm afraid I cannot elaborate further, I must sleep.
-
But the fusion won't happen at low temperatures. It gives off a LOT of energy (heat) to power the turbines, but the reaction itself won't happen until at about 100 000 000 Kelvin.
When atoms heat up, they move faster. If the heat is large enough, the momentum can break the repulsion, thus fusing the two atoms. The problem is that it currently takes more energy to start the reaction than the short, unsustained, reactions give off. When some decent fusion reactors are built, I'm sure the reaction's energy flow will be positive (http://dynamic.gamespy.com/~freespace/ubb/noncgi/smile.gif)
But cold fusion? Umm... no.

Surround the Tokamek containment unit in a sphere evacuated of all gasses (except for the contained nuclear plasma. Surround that sphere with another one and evacuate the space between them (it is important that the two spheres are electrically insulated from each other). The inner sphere should pick up a positive ion charge as the radiation knocks electrons from thier orbits (turning it into an ANODE(+)). The outer sphere will 'pick up' the lose electrons and pick up a negative electrical charge (turning it into a CATHODE(-)). By connecting the two spheres with a conductor, electric current will flow between them. This electric current may then be passed through any load device to generate work.
...TA-DAAA! Efficiency and current generated will depend on radiation intensity (a function of amount of plasma, energy state of plasma, and distance between plasma and anode) and the surface area of the anode and cathodes.

Or you can use magnetohydrodynamic couplings (whatever the hell they call them) to get energy right out of the plasma, although I think this only works if you have some sort of toroidal setup.

the first nuclear bombs particularly the hiroshima bomb used a "gun" to start the reaction, basically hit two bits of uranium together hard enough and "BOOM"

? I'm not sure if it's the same thing, but what I know about MHD is that it's used to move in a dense element (air, water) thanks to magnetics fields (and that it works damn well, so I'm still waiting someone to explain me why submarines and planes won't use that...)

Actually, we heat the gasses into plasma not so much for the kinetic energy it develops (we could use particle accelerators for that) but the fact that when we get them hot enough, the atoms shed their electrons, thus making it easier for the atoms to fuse.
And my gods, I can't believe I didn't realise that... thanks jonskowitz... that really does make me want to kick myself, but I already headbutted my knee yesterday so I'll give it a miss (http://dynamic.gamespy.com/~freespace/ubb/noncgi/wink.gif)
And Jabu, that's why cold fusion doesn't really fit into the Physics thing, cause the atoms are joining at a low temperature...
Of course, it might not actually be fusion, but in that case it's debatable what's actually happening.

The way (I think) it works, is that the plasma, as it's going around the torus, generates a strong magnetic field, which is used to directly power an electrical transformer.

the plamsa does create a meganetic feild of its own but its not to produce energy it just serves to help contain the plasma cause to do it all with the reactors fields would require alot more powerful electronmagnets
and the cold fusion thinga bout giving off heat somesaid that the create largers molecules - thats it exactly molecules not elements- in fusion hydrogen turns into helium basically - what your talkina bout is like pouring acid into a alkaline you ameracans call them bases or something produces heat etc but its not an atomic reaction its a molecular or chemical reaction - only true fusiion is the kinda that involved alot of heat
and that idea for extracting power from a fusion reactor is that fact or did you jsut think of it and if you did think of it do you happen to have a degree in nuclear physics? cause if thats true and it sounded plausible then that is very cool indeed
and finally - the first nuke acaully used explosives very carefully shaped to create an imposive shockwave in a sphere or plutonium or was it uranium i can never remmeber which is which - as i understand it they shaped the plastic explosives to lense the shockwave directly evenly around teh sphere so it compressed the plutonium and resulted in it achieving critical mass and bang
hell if you have the right ingrients any fool could make a nhuke although it would be small one and might not go off correctly but still create a far bigger bang than a normal bomb - just need to stick your sphere in a ball of plastic explosives

The idea for it was based off of current designs for NASA'a plutonium batteries used to power deep space probes. But the theory that makes it works is as old as vaccuum tubes!

No, I didn't make it up. At the moment though I couldn't give you a link or anything, it was something I heard a while back.

It was stated that not all elements can be fused, if they can't then how do you get anything bigger than iron, it has to be put together somehow.

Yeah,I invented Pants
You can thank me later
-
elements heavier than iron are formed only in supernova's or the very largest of stars

Transiron elements cannot be made in a normal fusion reaction, however, in a supernova the neutron flux is so high that all the heavier elements are made by the process of neutron capture.
