Mobile Fuel Cells Soon?
Mark Leaman writes "Motorola has made a strategic investment in Vancouver based, micro fuel cell developer Tekion with a view to the inevitable rise of the fuel cell as a power source for mobile products. Tekion is creating a new "personal power source", known as the Formira Power Pack, that will fit inside mobile products and enable consumers to stay connected for as long as needed. "
will . . . enable consumers to stay connected for as long as needed.
The problem is this: battery life is never long enough. This is true for three reasons. First, as battery life improves, consumers come to expect more. Second, electronics manufacturers will see the marketing opportunity in "we have the smallest $gadget on the market", and will put in the smallest acceptable battery. Third, as we have seen with computers, manufacturers will continue to pack (some useful, many not) features, sapping that additional power.
Granted, fuel cells have considerable energy-density advantages over current chemical cells, but it will never be enough until we have devices that will *never* need a recharge, battery replacement, or refill.

Honestly, if 1.5hrs talk time on a cellphone is too little for you, then you made a poor choice when deciding which phone to get (ie the features vs battery life dilemna). I keep my old feature-free Nokia 6310i for when I just need a phone, and my nice shiny new 6680 for when I want to pose with a fun gadget.
We've already had batteries exploding in Nokia phones, can you imagine it with fuel cells - "Oh, the Humanity!".

I'd like to think that one benefit of a fuel cell is that it can be recharged more rapidly. Given the choice between an 8-hour traditional battery that needs me to be tethered while it's charged, and a fuel cell with a 2-hour life that can be recharged in 2 minutes from a bottle, I'll go for the fuel cell. For most people, it's not battery life that's the problem, it's recharge time.
Boy, that's a light press release. The main question is unanswered: what does it use for fuel? Gin? Composted elderberries? It says "non-flmmable." Does that mean that the fuel cell itself won't catch fire while you're using it? Does it require a handy liquid-hydrogen refill tank?
And what the HELL is the deal with the light-blue on white typeface?
Never attribute to malice that which can be explained by mere idiocy.
Imagine a cell phone that doesn't need recharging. I'm sure that rescuers at a hurricane scene would have killed for an emergency transmitter like that. Even if something like this isn't as portable as modern flip phones, it could still mean the difference between communicating, and not being able to when electricity from the wall isn't available.
A golden age of energy accessibility may be at hand, and could open up parts of the third world to modern technology too, if it has a readiliy available power source in those places.
Saskboy's blog is good. 9 out of 10 dentists agree.
true mobility. Connected and powered 24/7, anywhere.
Would be nice wouldn't it? Unfortunatly, there are exactly three devices that can make this happen:
1) A portable solar generator and battery. This only works as long as the generator is able to produce more than ample power to cover periods where sunlight is unavailable and the panels are always facing the sun. e.g. The roof of a car. Plus you still have to charge devices in it.
2) Beaming power to devices. This is actually related to solar power as it reqires that a laser or maser hold a targetting lock on your device's power converter. Besides how tricky this is to implement, it's also dangerous to be broadcasting a number of lased transmissions in the multi-watt range.
3) Harnessing the radiation from radioisotopes. This is the most promising option as there are several types of radioisotope that are easy to contain, and no more dangerous than today's battery chemicals. This option could easily provide power in the 1-50 watt range, 24x7 for 10-30 years. The drawbacks to this method are a) radioisotopes are too expensive, b) the public has an irrational fear of anything "nukular", and c) the radioisotopes must be treated as hazardous waste (just like batteries) and disposed of properly.
I fully expect that option 3 will be embraced by future space explorers. It just wouldn't do to have equipment that can't survive long spans of time away from a charging station.

That depends... "Well I was smoking my sigarette while refilling my cellphone and then I woke up in the ambulance. "
The formic acid battery, when ruptured, is marginally less toxic than the matter-anitmatter battery.

Granted, this means you won't be refilling from a gallon jug -- you'll be locked in to some form of replaceable, well-sealed cartridges.
And I think this is my point. We're talking about a supposedly convenient new thing... but it only works if you have access to carefully sealed, probably proprietary injectors of nastiness. A pocketful of Li-ion batteries would probably be just as easy to maintain, and still get you that long usage. Just develop some nice little solar handkerchief to unfold and charge them, or something. But I don't find much liberty in having to depend on a source of formic acid - however stabilized - for my phone to work. It's just like printer ink.
Don't disappoint your bird dog. Go to the range.
I am concerned about the standardization of the "refueling" functionality. If every fuel cell maker out there uses different valves, nozzles, ports, connectors, whatever for putting fuel in and removing the wastewater, we will jump directly into a confusing nightmare of incompatible plumbing. "Oh, yeah, my cell phone takes a 0.7mm bayonet fuelling nozzle, but my PDA takes a 0.05 inch tapered friction connector." So you still carry four little fuel tanks with you to power your cell phone, PDA, iPod and laptop.
A different question is what airline is going to let people take devices powered by flammable liquids on board, when they're already disallowing butane lighters?

You could have longer talk time, but "the public" insists on smaller phones/laptops whatever every year. If consumers would be content with the size phones were 5 years ago, not giant bagphones like in the olden daze, just what size was common back 5 years ago, with smaller and better electronics but bigger batteries, they would last much longer, even with todays battery technology and more powerful features. When you shrink *both* the battery and the electronics, it's like, what do you (anyone you I mean, joe consumer) expect? Lithium ion tech is pretty spiffy now, make it big enough, it'll last all day long easy. And it doesn't have to be ridiculous large, but then again, phones are getting ultra ridiculous small. I know I can't use the teeny phones, can't see the screen easily nor use the buttons. My "choice" is extremely expensive larger PDA like phones with reasonably sized screens and buttons and bateries, or teensy tiny phones that are barely useable. Older phones with good enough screens you can't get batts for hardly anymore, plus the providers won't activate them if they don't have that location feature in them for e911 stuff. Just went through that at the cell store. My older phone they refuse to activate now, even though it works perfectly fine and they used to provide service for it. Had to buy a cheaper smaller one. Nuts...grumble... this is verizon by the way, they have the best coverage and cheapest rates around here, but it could be any of them really.

What I would like to see is standaridzation WITH the batteries themselves. Propietary sizes and configs are a pure ripoff, you go to replace the battery it costs 2/3rds what the entire device costs new. I just happen to get a new phone two months ago, it cost IIRC around 65$. I asked what a replacement batt was-50$.
Ripoff. We have standard sized batts, AAA, AA, C, D etc but they just won't use them, has to be different, force you more or less to keep upgrading the entire phone. I have HAM portable transcievers that run multiple watts output, they run fine on regular config batteries. What are cell phones, half a watt or something? I just got some GMRS/FRS talkies, they just use normal rechargeable AAs, no need for some weird "package" battery pack that costs ten times would it should.
