When lithium batteries burn, a chemical reaction actually creates its own oxygen.
A year or two ago, some of Elon Musk's giant lithium storage batteries caught on fire in Australia.
The FD did not even try to put the fire out.
It burned itself out after several days.
Imagine a world where millions of those batteries will be located in under ground parking lots, below fully occupied apartment buildings.
Multi-level parking structurers.
A terrorist or saboteurs dream come true.
A better analogy would be jet engine vs. rocket. A jet carries its fuel, but needs the atmosphere to provide oxygen. A rocket has an inherently unstable fuel that only needs to be initialized to start a reaction. Li-ion batteries burn like rocket fuel, not jet fuel.
