Reply to comment by IParkForFree in Are exothermic chemical reactions a possible avenue for energy? Or is this done regularly today already? by xombie25

I think OP is imagining a perpetual energy generating reaction with no downside (such as reactants getting consumed). As /u/chemchris says, and I extend a bit... mass-energy does not get created or destroyed (noting Einstein's E=mc^2 converts mass to energy, as we see in nuclear fission).

I guess what i’m saying is, you need fuel for an exothermic reaction. There are a million possibilities here. Which fuel is OP referring to?

Yeah - that's the point I think. Maybe OP thinks an ecothetmuc reaction is creating free energy!!
