If the fusion process of a fusion reactor fails, no blackhole will be created. For creating a black hole you need an object whose diameter is smaller than its own Schwarzschild radius. As an example, the sun must became 500 times more massive (with the same diameter it has now) to become a black hole, and the earth diameter should be arround 0.1 milimeter to become a micro black hole.

The first REAL problem with a fusion reactor is that we DON'T have a high temperature alloy to contain the reaction. The second REAL problem is with the activation energy for hydrogen fusion. In the present time, the only thing that can produce enough energy to start the reaction of enough Hydrogen to power a fusion engine is a Plutonium warhead (view info for the "H-Bomb").
Black Holes are not created from fusion explosions, they are created from the colapses of great stars (Super Novas), that creates a gravitacional anomally that "sucks" all the matter to it's vortex. So, it's nothin more than a great concentration of matter in a little point. The resulting eletro-mag field is so intense that bends the space (like Stephen Hawking said) around it. One more thing: don't belive in the casual speech of the light bein atracted by the Black Hole. The truth is that the light is bended when near a black hole, always following a strange route. So, sometimes, if u look to a black hole, u'll see a black spot (from where his name came) and sometimes u'll see right trought it, just like was nothin there.
This is only theory... No-one ever seen a black hole.

There is no alloy that can handle 200.000.000 degrees kelvin.
The only way to contain a fusion reaction is by using a strong magnetic field...
I ve heard of a successful experiment in some place of europe (dont remember where exactly). They achieved fusion during a few miliseconds...
For activating a fusion reaction you have to put hydrogen under great pressure and temperature. 200mill K i think, not sure...

I have actually been "playing" with one of those magnetic fusion containment experiments.....3 years ago
One of the very small ones.... actually the smallest one in the world operational now.
Parameters:
major radius R= 0.4 m
minor radius a= 0.085 or 0.060 m
toroidal magnetic field Bt < 1.5 T
plasma current I < 25 kA
pulse length t < 50 ms
plasma density ne= 0.2-3.0 e19 m-3 ........that's VERY low... compered to the air
electron temperature Te(0) < 200 eV ..... that's about 2.3 Million Kelvin :)
ion temperature Ti(0) < 100 eV
Once I was working on a computer that is one floor above and a bit to the side of the reactor (about 10 meters in a straight line), when someone "shot" the reactor (for <50 ms as it says in the parameters).
1.5 Tesla is not extremely strong magnetic field.. but still it was enough to make the image on the computer screen (old tube one) disappear.... and then slowly come back... almost line by line :)
To get more energy than you use out of a fusion experiment like this you need to achieve:
1. Temperature
2. Density ....... note lower than air!
3. Confinement time .... before all the electrons and ions run away
Currently the furthest this technology has come is at the JET reactor in UK...
they have achieved a Q factor of about 0.7 (meaning they got 70% of the energy they used to "ignite" the plasma back).
The ITER reactor which will be about 16m in diameter is under construction in southern France now... expected to start in 2030. It's expected it will achieve Q ~ 10.
EDIT: You actually posted a link to wikipedia there, so that's where most of the things are said.

ok i have no idea how much relevance this has to this topic but....
why dont we have actual Slug throwing weapons ingame (by slug throwing i mean good ol bullets). i mean seriously what happened.
id like to see more solid round based weps ingame,
who knows, it could be an effective weapon against the nomads?
but seriously (on topic now), how accurate is the game?
in my opinion it aint too accurate.
if you want a more accurate game - try out "frontier" ... the elite ( real classic ) sequel.
a few features ( theory )...
- planets have multiple cities, real atmospheric flight ( no cutscene from space to planetary landing ) - transports MUST dock in space or MUST hire shuttles to deliver to the surface.
- distances are measured in astronomic measures - i don t really know how much 1 is, but its a lot of miles...
- jumping happens based on the mass. you get funny effects - ( cruiser jumping from system 1 to system 2, 1 week later, a squad of bombers launches to take it out ! .... due to their lesser mass, they happen to jump 1 week later, but appear before the cruiser does. so they ambush it.
- spaceflight happens in 3 parts: appear from the jumphole at nadir / zenith ( above or below the star ) and head to the planet of the system ( they are moving based on distance / mass from the star )..... at first the ship accelerates untill you get a tunnel view flying at like several million miles / second .... at around half the way to planet, the ship performs a perfect turn and starts the breaking manouver untill it hits the orbit of the planet and starts the landing sequence.
- magnetic fields, nebulas, sun winds, etc. etc. affect the ships
- there are like dozens of different ships out there from one man shuttles over liners up to battleships.
--------------------------------------------
result:
one of the most accurate space games. free roam, open end, etc etc - a bit like freelancer might have been. BUT!!
guess what - its boooring. dogfight at 6.000.000.000.000 miles/ second? - forget about it.....
load your cargo hold full with perishable stuff? - yea, but make sure you re not flying a heavy transport, cause the jump will take months....
fight a battleship in your fighter? - have fun, mass drivers and slugs are neutralized from shields.... so are little fighters.
but for those that don t know that good old game......... its a free download - it is in a way awesome! - just not really funny as a game:laugh:
I did a big long presentation on nuclear technologies and their possibilities and limitations. Wonder if I can find that somewhere. Korrd the Fusion reacotor, I think, your thinking of is ITER (International Thermonuclear Experimental Reactor) which is currently in the planning stages and will attempt to obtain a sustained fusion burn. Another interesting fact, Cold "Fusion" isn't fusion at all, it is a chemical reaction on a new scale we don't understand yet, but could be a viable source of energy.
I also did a competitive speech on black holes and if you don't think Hawking is a crackpot then you might to interested to know that miniature black holes plague our atmosphere but to no ill effect because they don't exist more than a few picoseconds.
As far as FL goes. It's all wrong, warp engines, maybe but everyday we grow closer to antiquating Einstein's theories. Though valid in many cases his theories are ultimately flawed when taken to extremes. The thing in FL I think we are closest to achieving is nanobots. Robots are growing smaller and more autonomous.
