Forever Flashlight

Forever Flashlight

We've all been there — the power goes out during a storm and you reach for the flashlight, but it's completely dead and there's no batteries in sight. Wouldn't it be nice if there was a flashlight that never needed batteries? There is. The Forever Flashlight ($25) uses electromagnetic energy created by you to produce light on demand. Just shake the flashlight back and forth for 15-30 seconds, and enough
electricity is generated to light its bright
blue LED bulb for up to five minutes of
continuous use.
