Self-Charging Smoke Alarm

here are some things you're allowed to slack off on, like ordering take-out once in a while instead of cooking a healthy meal. But you would never slack off, of course, when it comes to the safety of your family. As you know, a smoke alarm on each floor of your house is a must-have. But it's difficult to keep track of which ones have fresh batteries. Luckily, DuPont has invented a self-charging smoke alarm that connects directly into ceiling mounted light sockets. Every time you hit the switch for your light, the smoke alarm automatically recharges -- no batteries needed! Another huge bonus is, the next time you set your alarm off frying chicken, no need to frantically wave a newspaper at the detector; simply flip the light switch three times to silence the false alarm.
