If you are anything like us, and you may well be, you forget to do things like change the batteries in your smoke alarm. Or, worse yet, you remember to take the batteries out when the thing starts beeping, but you forget to replace them. One potential answer to this problem is the self-charging smoke alarm. Simply screw the detector into a ceiling mounted light socket (providing you have one) and never need to change a battery again. This is an especially good idea for places where fires start, but people do not always go, or would not be annoyed by a beeping reminder. Garages, laundry rooms, etc. They’re a bit more expensive than your typical cheap-ass smoke alarm, but may be worth it for the forgetful among us.—MEGHANN MARCO
