    this is my first post here, and i more or less made this account to ask around about this.

    now to get to the topic.

    i am a power armor/mech-armor/exoskeleton fanatic. ever since i first played the game halo combat evolved that im sure many of you know about, i have had a love for powered armor. this has not been helped by the taunting of 2008's release of "IronMan" in theaters, nor by Bethesda's "Fallout 3"(i get a lot of my knowlage from videogames ) over all they all had some sort of mechanized battle armor.

    i ahve recently tried to follow some Real information on powered armor, and have used the movie "ironman" as my best source of current information. this has lead me to one major delema. The power it part....

    sure you could use batteries of some sort, but unless you put a lot more armor in that particualr spot it's a waiting hazzard to end up with a stranded soldier.

    so i looked back at what i knew,(re-watched Ironman ) and noted it's power source. the "Arc Reactor." i dont believe that a free limitless power sourse can be found just out of the blue, but it did lead me to think about energy as a whole.

    but the arc reactor somehow goes from being an electrical source rignt into an explosive energy to make him fly, and then into an emp source as shown in the end of the movie.

    basicly i wanted to ask, does any one know anything about different energy sourses?
    not like nuclear, gas, enthenol,... ect...

    i mean like energy conversion. the method the energy is applied.
    all engines, power plants, ect, all take one form of energy(nuclear, coal, ethenal, gas) and convert it to electricity using a generator!

    i wanted to know if there are any exsistance of raw energy, that can be applied with out a conversion into electricity.

    (sorry for the long ass post to read, but i've been thinking on this for a while, and thought i should explain my idea.)

    There's always some loss converting one energy to another, and generally a lot of machinery around that too. For example all the bulk of a car really accomplishes, is transfer the pressure of a gas explosion to wheel torque. Conceptually that could be a simple small mechanism but we've improved it over time to remarkable weight and complexity. The losses of transferring energy generate heat, and that heat must go somewhere. I think if Ironman has the power of a freight train it'll need a radiator of the same capacity.

    There are some (real life) cooling suits that scream incredibly fast air under the fabric. They employ a fuel burner to create the suction. So for Ironman I think better than a huge liquid-circulating radiator he should have what looks like a flamethrower blazing off his back, and numerous air intakes. Then his powered suit thermostats could regulate the flame and airflow as required.

    i guess, but your still talking about converting one energy into electricity,

    i was asking if there were any energy sources that dont require energy conversion. that can be used in raw form for multiple power sources.

    like is there some way that a nuclear reactor that doesnt need to heat up water to turn turbines.

    or like some sci-fi ionic/plasmic energy that uses the energy of moving particles

    I think I understand what your saying, which is, can't I have a supply of energy in a battery on my back thats flying me through the air, whilst running a computer in my helmet, whilst charging my shield suit.

    The thing with energy is that you've got to remember it doesn't exist in some "pure" form, the word energy is like a verb-its a doing word. Its a doing thing. For example, petrol is a form of chemical energy, thats to say when you combine it with something like oxygen, heat and expansion occurs. A battery contains electrical energy, with electrons pushing their way down a wire from one side of the battery to the other.

    What I think your really asking is, can I have the suit from Ironman or Halo. And god knows I want to be master chief sometimes. The truth is unless we find really, really efficent ways of flying, like some sort of anti-grav struts, we need a hell of a lot of energy. You aint gonna do 200 mph with a duracell battery. I think in the halo universe the spartans have two cold fusion reactors. This is using the immense amount of energy that is released when you start playing with the bonds inside nuclei(or atoms). In Ironman, the "arc reactor" uses polonium isotope something or other, and doesn't really explain how the energy is created, but its probably along the same lines as the fusion reactors.


    In essence, these sort of mech suits are possibly possibly possible, but unless you have a trillion dollars or some major breakthroughs happen, we won't see them in our lifetimes. More likely, we are going to see less powerful enhancements for soldiers that make them run faster, carry heavier loads, and have microcomputers to help enhance their aim, communications, etc. Hope that helps.

    A better and more realistic movie to watch is the Alien series, in which Sigourney Weaver at one point ends up doing battle with the alien monster while wearing a power lifter. The whole thing was about the size of a small fork-lift. That is much more likely than a power suit such as Heinlein wrote about in Starship Troopers.

    To get sufficient power, you will need something like a motor mounted on the back. Imagine a lawnmower engine mounted on your back, roaring away, and driving the power suit. Even a futuristic suit will need something like that, though presumably a lot more efficient than modern engines.

    Perhaps you could mount a jet pack on the unit, and fly.

    With regard to the Iron Man suit... presuming the arc reactor provides essentially unlimited electrical energy and power, the leg jets we might assume simply use electrically heated air to provide thrust.

    I was thinking about how the tiny wires could supply all that power and I considered the possibility of allowing that these are control wires (plus the supply for the electromagnet keeping the shrapnel out of his heart) and that the main power is supplied inductively by a coil around the arc reactor.

    In your question you should be more careful with the term "source" I assume you mean instead "process". To address your more general question:

    One of the direct conversion mechanisms suggested in the Bussard Polywell fusion reactor would be to directly tap the ions emitted by the fusion reaction.

    This is done with "atomic batteries". The fast moving ions emitted either by a nuclear reaction or by radioactive isotopes can be tapped to create a current. Though the current will by tiny the voltage can be quite large (typically a million volts for say beta particles)

    Another way say nuclear fusion energy might be converted to electricity is by first converting some of the heat in the plasma to mechanical energy by letting it expand and then passing it through a MHD (magneto-hydro-dynamic) generator.
    http://en.wikipedia.org/wiki/MHD_generator
    Imagine say focusing a stream of hydrogen plasma with magnetic fields enough to cause fusion, then the hotter plasma emitted form the other side will expand and speed up. This output stream could then pass through a MHD generator and thence be recycled back to the input. (with possibly an intermediate stage where fusion products are separated out and more hydrogen added.)


    There are also thermonic generators (Peltier junctions) which can act both as a heat engine generating electricity or a heat pump using electricity to create a temperature difference.

    Is this the sort of processes you were asking about?

    dude i have been thinkin abt the same from some years but i finally agree tat its almost just a fantasy..wat powered the iron man armor was something that produced unlimited source of energy which is almost immpossible to be achived in our practical world ...any thing like tat can revolutionize the whole world..imagine goin outer space without any fuel and a greener earth.
