Screw-In Self-Charging Smoke Alarm

dupont-fire-alarm

Dupon offers probably the easiest way to get home smoke alarm (only Snapalarm may be simplier). Just screw its Screw-In Self-Charging Smoke Alarm into any available light socket and turn on the light for two hours each week to charge it. The backup power is good for 30 days in the event of a power cut.

This cool gadget retails for just $29.99 and comes with a 10 year guarantee.
