>>19443855>start the process and have flame to control, guide, and grow.It doesn't matter if you have a spark, and can control the movement of gasses somehow. Splitting the hydrogen and oxygen from each other in water will take X Kilojoules. When you combine (burn) them, you will get Exactly X Kilojoules back.
As long as this movement of gasses follows the laws of physics (which it does not, btw; at the very least this control of gasses will violate the 2nd law), which was stated in the first post about this, you will not get more energy out of a system than what there is in it. If you did have this weird control over gasses, you couldn't explode a room full of water, unless you are fusing the deutrium nuclei. Which I doubt, as that would take much, much more energy than you would have in your entire body. A better way to use this power would be, say, boil the nitrogen from their blood or carry a vial of some corrosive gas around to manipulate to your enemies. THAT would be possible within normal physics and this power.
