This fire alarm has some interesting features. The smoke detector incorporates an aesthetically pleasing, daily-use, dimmable light that activates during an emergency. In case of fire, the unit communicates with other like units to illuminate an escape route through your home. The unit is powered by your home's electrical power, yet doesn't rely on it. Instead, the device employs a long life emergency back up battery that activates during an alarm. Now if it only had a wifi notification system...
Freeplay has come out with a nice backup energy solution called Weza. The unit works by having the operator step repeatedly on a pedal to produce up to 40-watts of power, which charges an internal 12-volt battery. The Weza outputs to two jumper cables or, alternatively, a convenient cigarette lighter jack. An optional add-on is required for powering essential 120 volt devices, like your PVR.
