Something\'s not adding up here. Perhaps I missed something but the article says the cartridge delivers 12Wh, then later it says the energy equivalent of 1,000 AA batteries. I don\'t have the exact numbers handy but 12Wh is equivalent to maybe 3 or 4 AA batteries, not 1,000.

Very good invention. It is heartening to note more Industries are turning to Fuel Cells which may lead to HYDROGEN ECONOMY.

Sweet, but this needs to be put into a laptop battery form factor and i think Hydrogen will really take off when people have their own production at home. A reasonably sized solar panel and a small tank could sort out all your transportation needs.

From an other (serious) point of view the hydrogen economy has no future: http://www.physorg.com/news85074285.html

Where can I find the hydrogen charging station? Do they have a product?

I agree with CaptNemo about the numbers not adding up. An AA alkaline battery is typically rated between 1000mAh and 3000mAh depending on load. At a voltage of 1.5V, this equates to between 1.5Wh and 4.5Wh. Also compare that to a standard laptop battery (which is a similar size to the MiniPak) with 4400mAh @ 11V = 48.4Wh. Perhaps the fuel cell capacity is 12kWh (12,000Wh)??

@CaptNemo I agree its misleading, it seems the 1000 factor is over the lifetime of the refillable cartridge. On one charge you just get 12 watt hours, which really doesn\'t live up to the hype of this article. The Horizon website mentions a \'highly innovative home refilling station\', which clearly isn\'t portable. For now this is no better than carrying a few extra batteries for your phone.
Still, a good first attempt.

Great ! and using this cartridge - you can run a hydrogen vehicle, motorcycle etc ?

I love your web site, but what is it that you don\'t understand in \"No thanks, don\'t ask me again\"? Most annoying.

They claim about 12Wh from each pack, with a maximum power output of 400mA @ 5v Their site claims a maximum of 2.5W output but 400mA*5v is closer to gizmag\'s 1.5-2W So if your device is pulling 400mA to charge/run you\'ll get between 5-6 hours of power out of a cartridge, which isn\'t terrible I guess. It would have been nice to see a higher possible output, maybe 600-1000 mA @ 5v though Toshiba\'s also had 400mA so maybe thats the best they can get out of it from that form factor currently. A max 5W draw on a 12Wh battery would be a bit much anyways, but its nice to have that option ;)
