It looks a C4 or some explosive stuff at the first glance. It is actually a Fuel Cell Battery from Samsung for Military use. This ethanol-powered fuel cell is going to power military equipment next year. The DMFC (Direct Methanol Fuel Cell) is capable of powering up a laptop for 72 hours. Each of the batteries weighs 7.7lb. Tee tee tee…… Boooooom!!!!!! Just kidding.
