Panasonic shows two prototype batteries that use fuel
At a size that is not bigger than a battery that now might call “big”, Panasonic has introduced two prototypes of batteries that run on fuel. With a capacity of 200cc these batteries, which obviously are still in development, are capable of reaching a maximum of 20W or whatever it is, could provide 20 hours of battery to a laptop.
Surely it is not as fun as the life you can give your laptop is its size, which is like 2.5 boards of large batteries.
