Horizon unveiled their $100 portable fuel cell able to power devices which use 2.5 watts or less (5V, 400mA). It comes with several connectors for common portable devices as well as two refillable cartridges that are each supposed to provide the same total output as 1000 disposable AA alkaline batteries. The machine and cartridges are said to be completely recyclable with no heavy metals or toxic chemicals. The website doesn’t explain how cartridges are refilled or how much additional ones cost, although they do say a home refilling kit is coming soon. This is the first portable fuel cell for consumer use other than the more expensive Toshiba Dynario which is only available in Japan.
The MiniPak uses a combination of Horizon’s mass-produced PEM fuel cells and a new low-cost metal hydride storage solution, which is able to store hydrogen safely as a dry, non-toxic and non-pressurized material. […] The PEM fuel cell combines oxygen from the air with the stored hydrogen [to output] electricity via its USB port and trace amounts of water vapor. [GizMag]
I found it funny that the video below and some other sites I’ve seen this on seem to be making a big deal about how it can be used as a flashlight. Yes, the $100 portable hydrogen fuel cell can power a flashlight. That’s like getting a free BJ machine and saying, “You can flatten leaves with it for scrapbooking, too!”
