Amazingly light and efficient fuel cells
Samsung’s been toying around with fuel cell batteries for about three years, but now it means business. Rolling out first to the military, this ethanol-powered fuel cell is set to power military paraphernalia next year. But it’s not going to run laptops for a month as originally promised. (Pics)
This DMFC (Direct Methanol Fuel Cell) design uses methanol to create hydrogen for the fuel cell reaction, powering a laptop for 72 hours. Now all they need to do is get the weight down, because these hotshots top the scales at a hefty 7.7 lb — but still maybe light enough to be considered wearable.
