I suspect the proper time units are closer to months rather than minutes. > How much power would a bit of circuitry waiting for a "turn on! there's a new > message coming in!" need? You also need a much larger bit of circuitry for frequency decoders, speakers and all the rest of it, and *most* of it has to be on all the time in order to detect that there's a new message coming in. It's going to cost a lot more energy-wise to monitor a frequency continuously than what's monitored inside a smoke alarm. Can you point at NOAA weather alert radio that has a 10 year battery in it? Because you're going to need pretty much the same circuitry if you're trying to cram all this into a smoke alarm.
