If what I've read is accurate, protons are composed of 3 quarks, two up and one down. They are held together by the strong nuclear force, the same force that holds protons together in a nucleus, correct?
Well, atoms can decay, in that the force holding together the protons can be overcome, thus causing protons to be emitted.
But according to my last question, protons have never been witnessed to decay, so therefore, the energy holding them together as an entity must be greater than that between protons in a nucleus, right?
Basically, what I'm REALLY asking, is:
1) Would it be possible to harness the energy that holds together a single proton?
2) How strong is the strong nuclear force that holds them together, relative to the strong nuclear force that holds multiple protons together?
3) Would it ever be possible to build an engine that utilizes this energy?
Thanks...

Thank you for the replies!
@Sam D,
I'm a bit confused. Uranium 235, which is used in nuclear fission reactors, has a half life of 700 million years. So clearly, we need not wait for the decay to occur naturally, when we can make it decay almost instantly. Right?
Also, I've thatched together some information, which I believe answers some aspects of my question.
1)
http://en.wikipedia.org/wiki/Quark-gluon_plasma
Quark Gluon Plasma - it's the stuff that existed before the formation of baryons (protons and neutrons), so basically, it is the product you'd get if you "melted" a proton. According to wiki, the temperature required to create this plasma would be approx. 1x10^12 Kelvin.
Also, I talked to my friend about this, who recommended the following:
http://einstein.unh.edu/nuclear/overview.html
A research project which hopes to "determine whether the quark-gluon plasma occurs, and characterize its properties.".
He also said fusion would most likely have a higher output of energy.
