The Science of Iron Man
holy_calamity writes "New Scientist takes a look at the evidence-base behind the science and technology in the new blockbuster Iron Man, and finds it is pretty solid. From exoskeletons to real-time translation there are at the very least proof-of-concept demonstrations of pretty much all the glitzy tech the hero Tony Stark uses."

All that's left now is to find somebody who looks like Robert Downey Jr. in real life.
For once, it looks to be at least within the realm of possible science (i.e. real science-fiction as the term implies, not the usual hollywood acid trip scripts).
Oh, and none of the "I got bitten by a mutant spider/got exposed to gamma ray/etc" crap that is usually associated with american super-heroes.

That is not really the Science Fiction part of the story. It is just a plot forwarding device to explain how the person got the powers. Even Iron Man really isn't Sci-Fi they are more under "Modern Fanticy"
Good Sci-Fi uses unheard of technology or really advance technology to forward the plot. Bad Sci-Fi uses unheard of technology or really advance technology to resolve the plot (I talking to you Star Trek Fans (Espectially Voyager))
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
It's nice that Stuart Ross thinks he can develop rocketbelts to enable people to fly. However, until someone comes up with a way to store the, apparently, unlimited fuel necessary to power a suit such as Iron Mans, and have it weigh, again, apparently, next to nothing, we will never see flying suits of armor.
Forget for a moment that a large percentage of people can't safely drive a vehicle on the ground at 65 mph. We now want to develop suits of metal capable of flying hundreds of miles per hour (Iron Man can out run jets and other craft)?
Then there is all his armament that he carries within the suit. How many rounds of ammunition, not to mention various missiles and such, is he carrying? Yeah, I thought so.
Yeah, yeah, I realize this is all fantasy and it makes for good enjoyment. But let's not get ahead of ourselves and try to claim that everything developed in a fantasy environment is directly translatable to real life.
Super-duper computers capable of interacting with humans? Sure. It will take some time but it is feasible and most likely probable. New uber-compounds which can retain their shape or make repairs to themselves? Already happening. Suits of armor capable of flying hundreds of miles per hour? Not gonna happen.
On a side note, is it just me or do Downey's whoops and hollers sound flat? I realize he wasn't actually flying but his yelling just doesn't seem, to me, to be indicative of someone who's flying in a suit of armor.

And we'll never be able to make a computer small enough to fit in a shirt pocket.
Science-fiction is fiction based on science. It doesn't require actual, current technology, only theoretically possible technology.
Just because you think it's not possible with today's technology doesn't mean it'll never exist.
In any case, a rocket-jet-inside-a-shoe is still at least more believable than some guy being bitten by a spider who can then hold a tramway full of people with his bare hands.
after watching spiderman, i was so psyched.
I went right home, caught a spider, microwaved it for a few seconds to mutate its DNA a little bit, then I took it out and let it bite me.
and guess what?
No superpowers
spiderman is bullshit.
this ironman fellow, this is real superhero stuff for sure...

The article contains some spoilers. If you want to see how the movie unfolds for yourself, save reading the article until after you've seen it.
Hey, no spoilers! The movie isn't even out yet. Next you'll be telling us some other important plot point, something like him rising from his grave to kill the people he once saved. Have some respect.
I got a kick out of them using the old Black Sabbath song. Since, far from being a savior, Iron Man ends up destroy all humans. I'm not sure if that is what the movie makers intended.

Iron Man's Suit Defies Physics -- Mostly
By James Kakalios
Tony Stark's amazing suit is a long way from realization, mostly due to practical energy constraints.
As a comic book fan and physics professor, I am looking forward to the big screen debut of Iron Man. This is due, in part, to the fact that instead of getting belted with gamma rays or being born a demon from hell, industrialist and scientist Tony Stark got his super powers by means of his engineering genius.
But just how realistic is Stark's amazing suit?
Sadly, nearly all of the features of the Iron Man suit, with one important exception, are not likely to be realized anytime soon. Let's look at each of the suit's major elements in turn.
Jet boots
The reason that we don't fly to work using boot-mounted jets as Iron Man does has nothing to do with technology and everything to do with energy. We know how to achieve thrust and propulsion using personal jet packs, and a person can indeed fly from home to their place of employment like Buck Rogers or Adam Strange -- provided they live 30 seconds from work.
The problem is that lifting a full-grown person 100 feet into the air considerably increases their potential energy, and that gain in energy must come from the stored chemical energy in the jet pack. Ditto for the energy required to zip around once airborne. You just can't store enough energy to make long flights without making the suit too big to wear. So jet boots alone don't make Iron Man an escapist fantasy, but the idea that Stark could store enough energy in his suit to fly for more than half a minute does.
Repulsor rays
Similarly, the directed energy weapons Iron Man uses, such as the "repulsor rays" built into the palms of his gloves, should require that Stark drag along a large power generator whenever he faces off against the Mandarin or Titanium Man. I'm not exactly sure what a "repulsor ray" is, but if it's anything like a high-power laser, then the energy demands are considerable.
Even assuming that Iron Man can convert any stored energy in his suit into laser light with 100 percent efficiency, then to generate a beam powerful enough to melt a fist-size hole through a half-inch thick steel plate (which any comic book fan can tell you is well within Shellhead's capabilities) would require an energy pulse of more than 2 gigawatts of power, greater than the output of a nuclear power plant.
Cybernetic helmet
There is one aspect of Iron Man's armor that is not only scientifically sound, but may be available for our use someday soon: the "cybernetic helmet" Tony Stark uses to control the devices within his armor. When Iron Man wants to discharge his palm-mounted repulsor rays, he does not have to manually release a safety switch, enter a firing sequence code or even pull a trigger -- he just tells the supervillain to "talk to the hand" and fires!
In fact, Bin He of the Department of Biomedical Engineering at the University of Minnesota has already created a helmet much like Iron Man's. It works on the principle that neurons' electrical currents create electric and magnetic fields, which can be detected with devices such as the electroencephalograph, or EEG. While the EEG has been around since the 1920s, recent advances in signal processing have enabled scientists to isolate and identify the firing signatures of neurons associated with particular motor-imagery tasks.
Professor He identified the specific firing pattern that arises when a person, watching images on a computer monitor, tries to mentally move a cursor to the left or right. These detected frequencies can then be amplified and, when suitably modified, can instruct the computer to move the cursor in the same direction.
Of course, He is not int
I always found the lesson Spiderman teaches a little weird; if you get bitten by a spider and start stumbling around and seeing everything blurred don't tell a soul, pretend like nothing happened, and go up to your room to sleep.

No.
"So, I think both spider-man and iron-man are equally possible."
neither are possible.
Both can be fun.

You didn't use the right kind of spider! You need a spider that already has some serious mojo that can be enhanced by the radiation.
I used a Brown Recluse. After a couple seconds of microwave enhancement, I let it bit me. And damned if I didn't develop a bad-ass super power:
Necrotic Lesions.
Sure, sure, doesn't sound like much. But you just have to be creative. Normally I keep them covered up, but when I'm say getting the jump on some bank robbers, I just expose my hideous gaping wounds and dead flesh, and they toss their cookies giving me ample time to shoot them or whatever. It's awesome. Everyone should get super powers like mine.

If you go back a couple dozen years it was outright impossible to build an engine capable of mach 2. We didn't have the science or technology to make it happen. It was maybe a glimmer in some technician's imagination, but that's it.
And before that we didn't even have the ability to fly at all.
Today we have cell phones with more processing power than an entire building full of computers a few years back.
We've got tiny motors in toys and gizmos that were also flat-out impossible a few years back.
Sure, by today's standards Iron Man is completely impossible, but that really doesn't mean much. I'm not claiming that such a thing will ever actually be possible... But claiming that our current understanding of science and technology is as good as it is ever going to get is awfully arrogant.
