okay, I will be the first to admit, there is a lot of thermal energy around but, I don't understand why almost all of the weapons used by umanity as a whole are exothermic (I've been thinking a lot about white phosphorous lately)
Probably because the point of an explosion (a lot of weapons are explosions) is to release energy, and some or a lot of that energy is gonna be released as heat. Chemical > thermal goes on all the time.. thermal > chemical not so often.
I am aware, I a more thinking precision weapons though right now we argue that we have missiles that can fly into an air duct problem is they blow up the whole building, so that precision is meaningless an endothermic weapon would have a more easily targeted area of destruction, which, yes would require more effort to target but I thought we were trying to reduce collateral damage? so isn't it worth it? (I know the physics involved, I am asking this as a moral, and strategic question, not as a "it costs more, so of course it's silly" question)
