I was listening to Matt Bracken on Rumble, and Matt brought up point I had not considered.
Israel just demonstrated a capability that should make all of us pay attention: the state use of wireless devices to execute a mass time on target attack.
What if, in the future, someone does this to cell phones of MAGA voters? Or, to get at Elon Musk, they do this to Tesla cars?
Not destructive enough.
These devices were rigged with small amounts of explosives. Lithium will burn like crazy but it doesn't react fast enough to cause overpressure. A lithium battery failing in your hand might fail fast enough to burn your hand, but it won't happen fast enough to blow your fingers off. It's not about the energy, it's about the chemistry. You need the right KIND of reaction. RDX and HMX get most of their energy from the extremely weak N-N bond, which REAAAALLLLY wants to become N≡N. Lithium batteries will get hot, they'll burn, they'll burst and vent hot gas... but they won't detonate.
