From the International Herald Tribute:
Moixa Energy’s latest innovation is one of those slap- your-forehead, why-didn’t- I-think-of-that ideas that simultaneously makes sense and makes us feel good to use: a traditional AA battery that recharges itself while plugged into a personal computer’s USB port.
Moixa, a British company, began offering its USBCell in September and, while executives won’t disclose how many they have sold, it is clear that the product is a winner, igniting a low-energy hum among the technorati.
