I agree. One would hope that when this research-level technology reaches the market, they can effectively isolate and contain the NaOH, and have some solid safeguards against malfunctions. On the optimistic side, we've mostly succeeded in doing that for other volatile things like gas tanks in cars and lithium batteries in electronics. On the pessimistic side, the failure modes can be very catastrophic! I'd definitely want to know what failsafe mechanisms are in place to prevent my house from blowing up before I'd consider using it.
