if decentrilized battery and solar power become economcially feasible they will be very popular.

but i heard some firemen say it would be a nightmare in case of a fire if every house has a battery charged with the power to last a house days (not to mention a big building) in it.

would it be possible to implement some sort of safety for this? a way to disipate the energy without it being dangerous? like some sort of controlled short circuit? im guessing it woudl have to be the most energy inneficient way to dispose of energy
