| Mar 9, 2021 at 2:49 | comment | added | Dan Bryant | @PcMan, That's not strictly true by definition, since our metabolism doesn't combust pure hydrogen with the oxygen, but, rather, carbohydrates. The energy is coming primarily from the bonds in those carbohydrates. That said, in practice, it turns out that the enthalpy of formation of water is high enough that electrolysis is a losing proposition, at least when using the oxygen to drive our current metabolism. To make it work, you'd need an altered metabolism with more exotic high energy fuels. Maybe something spicy involving lots of nitrogen. | |

Then you can biologically make use of the the energy in that fusion power pack which you otherwise could not make use of biologically. But you would not use any oxygen-fueled biological process for electrolysis, because that is a losing proposition. | |
