You've gotta either interest someone with the knowledge to pursue it or actually go to the college and gain the knowledge yourself. Because the truth is, unless you can motivate someone to do your thing, your thing isn't going to be as interesting to others as it is to you, even if it would be revolutionary. There's a good chance the idea relies on phenomena that only exist because of a lack of understanding (if you aren't able to go from idea to proof of concept), or maybe require a solution to a very hard problem just hiding below the surface.

Plus, even with the motivation, if you don't know enough to do the thing and aren't in a financial position to control the operation's finances, there's a good chance you'll be discarded once you are no longer needed, which in this case is once they understand your idea. That "sorry, not interested" might actually be a "go away, this is interesting but I don't think you'll add anything more to this, so I'll do it alone".

So instead of thinking "this is cool but I have no idea how", think, "what do I need to learn to better understand my idea and its execution?" Hell, even being able to break it up into discrete and complete steps would be a great start because then you can start hiring out those different steps if you can't do them, without having to give away the whole thing.
