Small self-contained energy source Answered

Hello,
           I am interested in making a energy source similar to iron man's arc reactor in the fact that it is small, self contained, and and powerful. I would like it to be hand-held, but I can deal with slightly larger or even desk size. It needs to be long lasting. I am well aware that an arc reactor is fictional, but I just need something that may be similar. It can be a large project (I have time) but needs to be not super expencive. Around $500 is the max I can go for! 
I hope someone can help,

Search on YouTube 'how to make a magnetic power generator' I'm making an improved version of this with about 2-3 layers of those discs on top of one another only just smaller.....

How much plutonium can you get for $500..?
2-stroke engines are pretty good for high power-to-weight. "I can deal with slightly larger or even desk size. It needs to be long lasting" - fits with a 2-stroke generator, you could get a few kw for $500.

Just to clarify, I want to MAKE the thing. Not BUY it!
Thanks for your answer,

You will have to buy things, so how much making do you actually want to do?
Would buying an engine and a generator separately, then coupling them together be OK?

Thanks for your opinion, but i want to do more thatn just hook to things together and be done.
thanks,

Making electrical generators is hard work if you're winding wire building armatures etc. Do you have some practical ideas about this, i.e. something you think you could make?

Not at the moment, but I think the one in the comment beneath this one is a possibility. If you can think of another that is not a "stick this cord into this socket and this socket and your done!" project, than I might do that instead!
Thanks for your input,

If you are willing to consider larger objects, you might consider researching fuel cell generators.

very interesting idea! I would have never thought of them! But that will be my second option, because I want to make it myself.
Thanks,

Good luck! Supposedly some are fairly straightforward to construct.

The key to designing something like this is to understand the term "energy storage density." You are asking for a device which stores energy (presumably electrical, if you want to operate existing electronic devices), and can release it in a controlled way, on demand. Batteries are the most efficient and highest energy-density small devices for this purpose.

Thank you for your answer, but I really mean a generator of sorts. A built in battery is a component, but I'm looking for the source of power.
Thanks again,
