With Sony already showing off hybrid fuel cell-powered chargers, it makes sense that we’re also seeing a hybrid battery for cell phones. Like Sony’s other prototype tech, this portable pack runs on a combination of methanol and lithium ion. It outputs a maximum of 3W and is good for watching 14 hours of digital TV. Sony labs plans to put these 2-inch by 1.2-inch batteries into production within the company’s operations division, but didn’t give a time line. One question, though: How do you recharge the fuel cells once they’re spent? Is the era of harnessing cow farts for good finally at hand? [Tech-On via CrunchGear]
