Designer Wonchul Hwang has come up with a novel design for a rechargeable AA battery. Unlike other batteries, this one pulls double duty as a 4GB USB drive.
The idea here is that it’s primarily a USB drive, one that you presumably keep hooked to your computer most of the time, but can serve as a AA battery in a pinch. What’s more, it’s a rechargeable battery that’s juiced every time you plug it into your PC’s USB port.
“Students or office workers mostly carry a memory stick,” Hwang explains. “If a memory stick could be used as an emergency battery, its use would be versatile, ranging from cameras to lanterns to speakers and other devices in outdoor activities.”
View the schematics here, and then hit the jump and tell us whether you think this is a novel idea or about as useful as a screen door on a submarine.
