Another non-sequitur:
Somebody pointed out that even small “innocuous” LiON batteries (like those in loud and long lasting greeting cards) that wind up in landfills can degrade, combust, and start hard to extinguish fires when they ignite methane etc.
Another “unintended consequence” of Lithium batteries might be, how do we get rid of them?
Maybe we can drop them in used-up lithium mines.
At some point, we’re going to have to develop a reasonably safe method of extracting the lithium from lithium batteries.
