@Aranor, I seriously doubt time was ever an issue for the second Arc Reactor. Tony had plenty of time after he came back (remember the first Arc Reactor still had enough power to power the Mark III armor for about 15 minutes and that was its rated max so he had near full power when he took it out) and even made the replacement bigger than the first one (look at the depth and compare when Penny swapped them). Penny also took the old magnet out so he had even more space after the procedure, so he could always double his capacity for the second movie. Though the fact he already had a conveinant hole in his chest probably factored, but since the Arc Reactor appears self contained that so long as that design remains the same that it needs room for both the reactor and fuel supply.

The obvious possible reason why he went bigger is likely that he put more reactor cores so it converted its fuel more efficiently (it did glow a lot more than the original) and the extra capacity would have allowed it to hold more fuel and thus power the armor longer. The first Arc Reactor only had the bare essentials to make it work and only enough fuel to last about 15 minutes at full power. So smaller reactors mean both less power and shorter sustainable reactor time before exhausting its fuel, adding more than one in different areas of the armor can offset that only so much.

The Omni-Beam is also like a thermal/heat vent, it's not just decoration and is not like the repulsors. So he would need to put additional such ports wherever he puts an Arc Reactor.

Which leaves only a few possibilities like either a radical Arc redesign or Rhode's getting some plumbing modifications to his chest done.

@Juggernought, the Omni-Beam is actually a staple of Iron Man design since the very beginning in the comics. The movie just made it the vent port for the Arc Reactor. Iron Man never had an Arc Reactor before the movie introduced it, but of course the director strived to make it appear more realistic (fictional power source not withstanding of course). A theme picked up by the comics as they have added elements from the movie, like how the armor now looks like realistic armor instead of armor like spandex cause it looked cool.

Originally the entire chest plate was the magnet and the Omni-Beam was an advance head light that later got weaponized. Modern version is linked to repulsor technology in the form of magnetic fields and linked to Repulsor technology. They even had Stane's son use the Iron Man tech to make Repulsor based suicide bombers.

For the movie though the Arc Reactor is just a pocket fusion reactor, the chest cavity plate is the magnet and just needs power to work. Even without the need for the magnetic field space is still needed for the Arc Reactor.

Stane only got away with not needing an operation because the Iron Monger was so big that it had more than enough space.

So this means one of the following. . .

1) War Machine will be a bit of a hulk, like the Iron Monger, to accomodate the Arc Reactor and not need an operation to embed it in his chest.

2) Multiple mini-arc Reactors placed over the body of the War Machine armor, each with its own omni-beam port. (Would differ from the traditional Iron Man design and add more vulnerable points enemy could target)

3) War Machine will only have a basic Arc Reactor with external fuel supply, so limited power and will rely on external weapons like chain gun and missiles for heavy fire power and limit repulsor power to primarily propulsion. Could also go back to comic idea of having extra power in hip mounted pods to compensate.

4) Rhode's gets turned into a Cyborg and becomes even more powerful than Tony. (Incidently all they have to do is have him seriously injured and not become War Machine until near the end of the movie to avoid distracting from Tony too much, it'll take time for Tony to have the armor built anyway)

5) Tony Creates a Hyper Arc Reactor that is small enough to fit into the chest plate and still provide full power, but would probably have some down side to explain why Tony doesn't give himself an even more superior model.

6) Tony sets up a power satellite network that beams power to Rhode's rig and he only has battery backup or basic Arc Reactor if cut-off.

7) Tony invents an alternative power supply, like perhaps War Machine will be a super capacitor and just absorbs energy as he needs it or Tony gets a fragment of Mjolnir (like he did in the comic) and uses it to power the armor.

Well, while we wait for the 2nd Film here's a fun little short animation. . .

Iron Man vs Bruce Lee: FIGHT!

With the movie out in less than three weeks...

Seeing the two trailers, it appears that the arc reactor is integrated into the armor itself. The War Machine armor is also bigger than Iron Man's suit.

We also have comicbook Stark's trademark suitcase sized Iron Man suit for this movie too. It's red and silver and definitely slimmer than previous ones. Whiplash also helps design the US Government(?) their own version of Iron Man suits. But my guess they're not suits but robots.

It's nice that Marvel is making their own movies because the suit case armor is a nice reference to the comics.

I can't wait to see this movie. My wife and I will definitely see it!

Me too.

Though I wonder if it will be any good. Trailers tend to make even a horrible movie look bad. With the exception of Sherlock Holmes where the trailer made the movie look bad but the movie itself is much better.

I am sure this will surpass the original.

Well I just finished reading the book version of the movie. In regards to Mcavoy questions do you really want to know? As it may ruin the movie.XP

Just read the book myself, and if the movie is anything like it, it'll be awesome!

Nope. I don't want to know. Iron Man was my childhood favorite superhero. It was Iron Man that turned me onto Guyver.

That's just what they showing the public now, imagine what other prototypes they got cooking up 'backstage'

Yeah, I'm still convinced that the Japanese have hidden underground warehouses full of Gundams and Armslaves and Landmates and Tachikomas and all manner of mecha's they're gonna use to kill us all >>

I don't know if anyone looked at the special features of the Iron Man 2 DVD/Blu-Ray yet.

But anyway Whiplash's first arc reactor only produces .8 GJ of energy which I guess is enough for what he needed to do.

Stark's arc reactor which I guess is a Mk. 3 is different from the first movie with how the core can be easily taken out and swapped out.

List of new armors: Mk. 4 is a slight upgrade over the Mk. 3. Mk. 5 is the suitcase one which is a carry over from the comics. Mk. 6 is the newest one with the triangle look.

I am curious about the Mk. 4 Arc Reactor though. How it interacts with the armor etc. I mean the movie gives you the impression that the armor is more powerful than the previous one. I guess it allows for certain new weapons that maybe the previous one couldn't do like the Laser-of-Death.

Another thing too is how Rhodey was able to link up with the Mk. 2 and also the fact that the Mk. 2 wasn't weaponized. I guess between the movies, Stark upgraded it so Rhodey can play too.

It also seemed odd that you would think a prototype from the first movie wouldn't be able to stand up to a newer model like the Mk. 4 but I guess Stark may have used the Mk. 2 still as a prototype for new technology. Or at least that's my theory.

So no one other then me has checked out the new iron man anime?

The Kid show one?

I stay away from kid shows, except for the occasional Bugs Bunny.

Uhh no an actual anime for older folks takes place between movies

Didn't know they made one. Last one I saw was the 90's one with the Modular armor.

Then again, I don't watch TV unless football is on... I mean American football.

Nope just came out done by MADHOUSE not bad I'd look it up.

I wasn't aware that the anime had started in Japan. All I have seen of it is the opening and closing scenes.

Yep its on episode 6 right now and its pretty cool.

I'll have to try and watch it sometime...
