Potentially huge news...scientist burns water.

[Angrist]

Yes, they electrolyze water to get H2, but only to store it for other use, not to produce energy. Again: law of conservation of energy.

Stupid comparison: the 2 main ingredients of apple pie are apples and flour. You can separate those 2, which will cost energy. When you smash the apples and flour together again, you get some energy, but it can NEVER be more than what it cost to separate...
Unless there's really something huge going on. Something atomic.
