Sony's new hybrid fuel cell 1.2 x 2-inch battery prototype has managed to keep the juice flowing to a cellular video broadcast for 14 consecutive hours off of 10mL of methanol. The micro fuel cell system uses methanol as fuel and is complemented with a Li-polymer secondary battery to help it deal with electronic peak loads. And according to the R&D team behind it, it may arrive to your gadgets "soon."
The battery prototype was made by the R&D team at Sony Material Laboratory, which told spectators at the Small Fuel Cells 2008 expo that it was in talks with Sony's operation division to push the tech out soon. Looks like the day when our gadgets can stay unplugged and awake longer than we can might finally have arrived. [Tech On]
