It is an interesting possibility, but I agree on the question of recharging. The heat generated could also pose a problem, but I wonder how long one of those could keep a G5 PB running?
 
so wait, to charge it you put methanol in it?! This would be great for travel but your accually using a substance to power it, Kind of like a car with gasoline.
 
It'll be inconvenient in a Powerbook. Imagine carrying a PB and a squirt bottle around with you. All I carry now is my PB.

And this cell would have to be much much larger to power a PB for any period of time, so carrying a large bottle may not be so convenient.

Toshiba plans to produce a notebook version of the fuel cells before this tiny one. This is just the early-adopter stuff. What I mean is that there's really no "methanol infrastructure" at this point. I'm sure the idea is to eventually have little methanol outlets (or something like that) everywhere so you can just plug in and juice up. I'll have to remember to invest in fire extinguisher companies.
 
It says it would give an MP3 player a 20 hour charge.. Which means it would give a powerbook, what? a 15 minute charge?

The 300 mW output of the bigger cell would be enough to keep a typical notebook's HD on standby. I think this technology has a way to go yet :)
 
If this technology does become good enough to power laptops, I think cartridges would be better than a squirt bottle.
 
When you inject 3.5ml of methanol into an mp3 player, say an iPod, and you use up its electricity generating abilities, what happens to the waste? Is it just water? Do you empty out the 3.5 ml of waste out? Is the waste toxic if someone were to drink it? Does this make the product unsafe for people under the age of 13 who might decide to drink it?
 
The waste will be nontoxic (CO2 and water) but the methanol is a problem (and it can't be denatured in a fuel cell).
 
This may be a stupid question...
...but why would anybody want to put a fuel cell in an iPod or Powerbook when a battery seems so much easier?

PS - aren't car companies trying to make cars with fule cells? We could just hook a diesel engine up to an iPod, that'd make it play nice and loud :D

Exactly what are fuel cells, from what I thought they were I would never imagine them in anything but cars, boats, etc.
 
i think the idea behind fuel cells (which are getting very tiny- definitely intended for consumer electronics, perhaps cell phones) is that although they require a substance, if that were easy enough to get recharges, the tens or hundreds of hours of power you'd get would be far more than a battery. There is a fear that batteries will reach a size limit, beyond which they can't hold any more power per cubic inch. Since electronics require more and more power, that's a real problem.

Advanced fuel cells are being designed to run on biomatter or biowaste, including a recent fuel cell that runs on a drop of human blood (it could power electronics that test the same drop of blood, making batteries unnecessary for blood sugar testers, for instance).

But for the most part, fuel cells won't catch on until batteries start reaching real-world limits.

Yeah I agree, what is the point of carrying around a little tube with methanol??? It only gives 20 hours charge..whereas a normal battery gives what 15 hours, but you can just plug it into a electrical socket and voila it gets charged. What happens if you dont have anymore methanol..then u screwed.
Plus with the increasing prices of oil..i am sure that one of those little bottles will cost mucho monies :D :D :D :D

And besides, who wants to cary around a little tube of methanol, couldn't it turn into a mini bomb? Guess no more iPods on airplanes :D

Methanol+Fire= Bomb
Any other battery+Fire= Bomb

Batteries are highly toxic, lots of lead, mercury, cadmium, etc. They're also not very efficient or long lasting. And, as has been pointed out, batteries seem to have reached the end of the line when it comes to size/power ration.

I think it'll be a few years before we see widespread adoption but I'm convinced it is the future.
