Actually, I would like that. As soon as I learned about common home fire alarms using radioisotopes to create a gap in an electric circuit that can be closed by ionized smoke particles, I was fascinated. I know there are some fancy ones that use optics instead so the can detect particles of any kind. The heat sensitive ones seem cool for cooking areas so there are fewer false alarms. I imagine by now there are ones thats use FLIR/thermal cameras.

All that is just detection. Even the communication is really cool. The loud beeping sound is simple but effective. I like the ones that release a spicy mist to wake deaf people. Flashing lights go without saying. Then there's networked alarms. Do they go straight to the Fire Department or are they like security systems that get filtered by a third party first?

The auto-response features (if that's what they're called) like fire sprinklers are interesting also. I read that they typically release dirty water because it's been sitting in the pipes for so long. Sure, dirty water is hardly an issue during a fire. It could be raw sewage and still be better than nothing. Still, I wonder why they're not on a loop integrated with the rest of the fresh water system. The advanced response systems like halon are kinda scary. Probably not something I'll see in my lifetime. I'm sure it's better than the alternative, though. The foam for airplane hangers is pretty neat. Wouldn't want to be in there, though.

I wonder what the cutting edge stuff is now.
