    If nuclear fusion were like getting laid... we'd have just reached first base.

    I really hope I live long enough to see fusion become a viable source of energy.

    'you can't destroy it. It's self sustaining."
    'I'll do it'
    From SpiderMan 2.

    Seriously, this is actually really cool. Can't wait to see how much energy they actually manage out of it.

    I don't know whether I should say it sounds like a cool idea or to say that this is not going to end well...

    To all those who actually take the near-catastrophe from Spiderman 2 to be at all scientifically credible let me assure you that it is not. The amount of matter actually used in a man-made nuclear fusion experiment or generator is no where near large enough anything like collapse into a black hole, start sucking in everything around it, or anything like that. In order to collapse into a black hole there's a threshold limit of mass that needs to be present. All the matter on Earth and the entire solar system isn't enough to collapse into a black hole.

    So yeah, don't worry about things that are scientifically so infinitesimally unlikely to happen.

    Yeah, but still... I wonder how many people had to kablam-y until dynamite was as stable as it is today.

    There's always gonna be "hiccups" along the way to a goal. This just seems like the kind of thing that's big enough that a "hiccup" would... Ya know... Destroy existence.



    But hey, who knows? Maybe everything will go a-ok.

    There really isn't anything that could go wrong, so much as there are only things that could be difficult to make work correctly. Conceptually fusion is incredibly elegant, just super duper complicated, technically speaking.

    This is my favorite part of it:

    Ah, yeah... That too. There's always gonna be someone that sees everything's potential to destroy and harm.


    ...some men just want to watch the world burn...

    Not to mention that, in real life, a Black Hole isn't this super-powerful vacuum cleaner of doom that it's always presented as in fiction.. It's just a large amount of mass in a (infinitely) smaller amount of space than its supposed to be. It just leads to disproportionate gravity, not amplified gravity.

    If our Sun were to some how spontaneously swap itself out for a Black Hole of equal mass (ie, without the devastating Solar Nova outright destroying planets), our solar system would maintain its orbits as usual, it wouldn't get sucked towards the center.

    I really hope this works out.

    It takes a lot of energy to make it work, but the output is potentially even greater, correct?

    This. This right here is the most important thing they did.

    And for everyone with all the "oh noes" stuff, fusion reactions have a totally different problem than fission reactions. Sustaining fusion is the hard part. Without the massive gravity of a star acting on the atoms, we need to "fake it" with pressure and heat.

    A fusion reactor, if damaged, would shut down, the reaction "fizzling out" without the sustained heat and pressure. There's literally no way it can be self-sustaining at the sizes we'd be using (less than oh...the size of a star), which is exactly the problem. Right now, every experimental fusion reactor takes more power to sustain the reaction than it puts out.

    Proper containment and "pinching" of the plasma would allow the reaction to keep going so long as we keep adding fuel to it. Ideally, the energy liberated from the fuel as it undergoes fusion can then be harnessed to run the containment itself, since the energy isn't coming from nowhere, but rather being liberated from the fuel.

    The stats mentioned by the article about deuterium are why this is such a big thing. This is literally it for us. Effectively infinite fuel from doping deuterium out of seawater.

    Makes you wonder why they don't run Cybtertron on this and just convert all the Transformers to run on water, huh? ;) 

    Oh, and MetalRyde, we already have fusion bombs.

    In fact, most nukes are fission/fusion bombs.

    Well, it's not like Transformers have harnessed fusion and like use it in cannons tha... ah.... nevermind... :eek:

    @Coeloptera: I was thinking something other then bombs.
