$\begingroup$ @MolbOrg for fuel to be useful as fuel, it needs to have a high energy density and a (presumably) very specific chemistry. In contrast, the stuff that you can find naturally in space and that gets bombarded in radiation all the time (asteroids, planets, etc.), tends to be very low energy as all the reactions that could've happened already did. Lunar regolith, for example, mostly consists of oxidized (burned) material. $\endgroup$

$\begingroup$ Hm, seems due the "dust" thing I automatically discarded the possibility of the thing to be a fuel. So I retract that comment. Still think you put too much focus on that decomposing, and not enough on conditions, as if it such a big deal immediately(and just one word about that it is not so), but yeah it being fuel it possible, even if it shielding for itself as well(outside layers). // @LiveInAmbeR this is rather what q-OP has in mind, MolbOrg just misread and misunderstood things, lol $\endgroup$
