Toshiba To Show Laptop Fuel Cells at CeBit
war3rd writes "According to The Register, Toshiba has finally been able to build a fuel cell for laptops that they will unveil at CeBit next week. The fuel cells are expected to last approximately 5 hours and are compatible with existing lithium-ion batteries. Form factor remains the only issue. The trick is that they use the water by-product from the cell to dilute the methanol source as it enters the reformer, and are therefore able to store higher concentrations of methanol in the cell. My only concern is how quickly can they get this to market?"
Finally we'll have a PC that can last as long as an iBook without needing mains power :-)
Follow me
hehehehe that makes me smile
Ignore the "p2p is theft" trolls, they're just uninformed
FROM HELL
etc.
If you want a fuel cell to be practically usable, you should make it run on 40% Ethanol, 60% water. That way, there is a commonly available fuel (Vodka) which can be easily purchased most everywhere in the US (outside Mormonstan at least).
If you can make the fuel cell deal with more impurities, you could also use Whiskey or Tequila or similar distilled spirits.

does it plays DVD?
It'd be nice if the component makers would establish an "open laptop" form factor. We've alreadt got mini-ITX. We just need a chassis/monitor and DC power specification.

We should take care not to make the intellect our god; it has, of course, powerful muscles, but no personality.
So I need to REFILL my laptop EVERY 5 HOURS on battery? I'll stick with my 6 hour transmeta.
People who think they know everything really piss off those of us that actually do.
My question is, how long will the battery hold up? I don't mean a single charge, I mean how long will the battery be usuable. Also, it states at the end of the article it will take 2-3 years to get to market. It's amazing that the poster of this story can't even read the article

Why stop at just laptops? Why not go straight to powering houses and cars?
but will it run Linux?
I'm not sure airlines or the TSA will be thrilled about people using fuel-cell-powered devices on those long-haul flights.
I RTFA, but still have a basic question - how does one recharge the battery? Will you purchase methanol packs, or just pitch the battery and get a new one? Either way, that cuts into the "environmentally friendly" bit...

"Runs for 5 hours" under what circumstances and configuration? I'll be downright impressed if they can get five hours out of a desktop PIV running full-blast, and running those drives full-time and the 802.11 won't help. I'd be impressed if the 'smart' battery/fuel cell realy was. My "10% low battery alarm" means anywhere from 5 to 30 minutes on a 2:30 or so charge life.
It's just like a fascist dictatorship, without the punctual rail service!
Making it run on 40% ethanol, 60% water, denatured with methanol (nondrinkable) also is good, for the "lower cost (no booze taxes), lower availablity" fuel.

Let's see. Now I can have a batter with a moderately longer runtime, but refilling it is much more difficult than simply plugging it in. Who's going to go for that? OK, it's cool. OK, it's environmentally friendly, but is that enough to overcome the convenience factor?
Even with a good catalyst like a fuel cell has, the reaction that takes place has a temperature of several hundred degrees Centigrade.
Sounds good for a little hot action on your laptop!
How do these things work? Do you really have to fill 'em up or are they sealed, disposable units?
A technology that lasts about the same time as a battery and will label you a terrorist when you board an airplane. Can't wait until these are out either.

Already, a big problem with laptops is heat. How much waste heat does this fuel cell produce. Looks like 40% is typical for large fuel cells, I wouldn't want to deal with that much more heat in a laptop.
cause it only takes a minute to throw some more fuel in (which you can carry with you) while recharging requires being tied to a wall power outlet for a few hours.
besides, why not just use a Transmeta chip with fuel cell power? Then maybe you'll get 10 hours before refuelling.
"My only concern is how quickly can they get this to market?"
Yes, dear slashdot editors, we're all aware of your growing concerns that you show in the last line at the end of each article.
5 hours of juice is about what my tibook gets now. After getting the mac I have never wanted for more battery time anymore. Now I want for CounterStrike though !!
I would like my laptop fuel cell to run on jet fuel. That way I could just pick it up at the airport on the tarmak.
Fuel cells would be great replacements for non-rechargable batterys, but not rechargables. Think about it. You hate to recharge your laptop, but you'll hate it more if you have to pay for fuel. You pay for electricity, but you don't usually think about it. You also don't pay for it if you charge your laptop at work. Yes, one way or the other we all pay for it - I'm talking about noticing it.
I wonder if arab people are allowed to purchase fuel for this laptop. Wouldn't it be considered "explosives", and the laptop owners "terrorists"?
OK, how good is this as a fuel cell? Can you hook up a fuel tank and run it as long as the tank is kept full? That would be great for emergency power applications.
Here is the methanol safety card. I don't see these on airplanes anytime soon. Anyway, remember those old photocopies from the 70's/early 80's that made pages with blue text? They always smelled a bit and came out a little wet. Yup, methonal was the fluid used in them....
-Sean
You "recharge" by popping in a new cartridge of methanol, which should be cheap ($3-5 initial starting price, probably down to $0.30 eventually. You don't actually have to plug the laptop in for a few hours to recharge it either, so on that long airline flight you can run the laptop indefinitely with enough little cartridges. I saw a pic of a prototype cartridge once somewhere, it looked about the size of a AA battery.
Isn't Hydrogen the desired fuel for a fuel cell? I may be wrong, but I thought that anything besides pure hydrogen would have additional exhausts besides just warm or hot water.
If that is the case, I am not sure why I would opt for this, being that it 'only' gives me five/six hours run time between refills.
That's another point - buying refills for every six hours use is a little bit more cumbersome than just plugging your laptop into the wall and charging the battery, even though the battery will not last as long.
If you are flying, at least you would be able to recharge your laptop. Might even be healtier, tomato juice for you, vodka for your computer.

Wow. Just when I thought I'd seen every type of pathetic loser, here comes the Subject Line Troll.
As others have pointed out, 5 hours on a laptop is *nothing* The batteries on my iBook do that just fine. Sure it takes me a couple of hours to fully recharge, but that's what a second battery is for, should I need one. Also, I don't have to refill, nor throw away spent fuel cells. It sounds like manually refueling would be a pain in the arse [for a laptop]. Vehicles using fuel cells sound much more interesting
What would be interesting would be a fuel cell laptop that got maybe 24 hours on a "charge".
This just seems like gadgetry for its own sake

Blocklevel: Practical Information Architecture
http://www.maxwell.com/ultracapacitors/ According to the above page, ultracapacitors "deliver up to 10 times the power, last up to 10 times as long, operate more reliably in high- and low-temperature conditions, require far less maintenance and reduce environmental issues associated with battery disposal" compared to batteries. I recently read about a hybrid automobile that will be using ultracaps (don't remember who). It seems like these could be implemented in laptops and cell phones.
Not to mention that the FAA requires the pilot be notified of all hazardous materials shipped on airplanes. (I'm in charge of hazmat auditing at a UPS hub). Having these methanol cartidges would require the passenger to have to register it or something of that nature, have it inspected, and a report given to the pilot of all of the laptops of this type on the plane. If this wasn't followed by the wonderful employees in baggage...hefty, and i mean HEFTY fines could result. For example, Emery Airlines was nailed for $500,000 for not notifying pilots of hazmats onboard. So...I don't see these on planes anytime soon either.
Give yourself a hitler?
No I didnt spell check this post...
Computer manufactures should focus on lower power solutions instead of building better batteries (or combine the two). My 17" Powerbook I ordered is rated at 4.5 hrs already with a standard battery. In general the pc world seems that the solution is always to throw more power at the problem instead of trying to come up with a more elegant method of dealing with it. (This isn't a rip on PC's I use both Macs and Pcs daily, just that there's more than 1 solution to most problems)
Hopefully they'll be able to squeeze them down to AA size. I have some lithium AA batteries for my PDA, and the battery life is a little longer, but the big plus is that the amperage keeps up even when the batteries are low. With NiMH (or NiCD I suppose) if the battery is low and you turn on the backlight, the PDA shuts off and drops to backup battery power. Maybe with a fuel-cell battery you could actually use the PC-Card slot on the road for more than 30 minutes without draining the batteries dry.
Democracy. Whiskey. Sexy. Pick any two.
Unfortunately, since the cells contain methanol, they would probably be banned from airplanes for security reasons. So much for flying with your laptop.

There will be an increase in risk for those people who use their laptop around large open flames. Hopefully these people will know to stick to regular batteries.
I really don't want a contained fire on my lap. I know Lithium-ion reactions are probably just as bad, but there's just a big mental difference. Do you really want something that can run your lawnmover on an airplane? Does the airline want it on your lap, either?

Ultracapacitors are not an alternative portable energy source-- check out specs before speaking. Wh/kg is 1/10 that of batteries-- they hold much less energy.
Ok, here's the ultimate use for Fuel Cell units like this. Install a espresso maker in the laptop. The fuel cell provides both water and heat. And Presto it fuels the laptop and the user.
Today is what tomorrow will be built from.
Just remember that these battery packs are for fueling your computer, not for drinking them like alcohol and then getting drunk with them...
guess that's why they say "never drink your laptop battery!" ba dum bum!
speaking of drinking laptop batteries as a substitute for alcohol, could I get another? ooh.. where do I come up with this stuff, I'm funnier than ALF

And, you can use any power outlet anywhere for free (except at home of course) whereas the fuel always costs extra - if you can find it.

Use the laptop on your lap and you will get wet pants.
Events like this would be more dangerous!
It would be more suitable for most of the executives I work with. They could top it off from the mini-bar.
The "safety card" for lithium.
It's doesn't seem to me that methanol in a sealed cell is any more dangerous than the lithium you have in your current laptop battery, or for that matter than the ethanol in the spirits sold as "Duty Free" on international flights.

So, what makes carrying a small AA battery-sized container of methanol any different than carrying a butane lighter onto an airplane? I don't see one. Not to mention all the other flammable products carried in small quantities on airplanes in cosmetics and toiletries.
As for the waste/disposal issue, the reason fuel cells are considered advantageous is that both production and disposal is cleaner, not containing toxic chemical compounds. The cartridges could easily be recycled into new cartridges...maybe even someday like inkjet printer cartridges.
As for the runtime on a single charge, that is certain to improve over time. The point is that they get new technology in the marketplace.

Do not confuse duty with what other people expect of you; they are utterly different.Duty is a debt you owe to yourself.
I believe the article was saying that the Intel funded fuel cell (Not the Toshiba product) would take 2-3 years to get to market.
"If it gets product out by then, Toshiba will probably be first to market. An Intel-funded start up, PolyFuel is working on direct methanol fuel cells for laptops. This delivers 150 watt hours hour battery capacity, three times greater than the best mobile PC batteries a day, but commercial product will take two-to-three years to get to market."
the US DOT has already approved one company's fuel cell for use on airplanes. It was mentioned on Slashdot here
I don't think fires or security will be a major concern. According to the article:
The technology uses water produced by the fuel cell to dilute the methanol to the 3-6 per cent concentration required for the electricity generating reaction. The upshot: the methanol can be stored at a much higher concentration, requiring a much smaller (ten per cent) fuel tank.
The wording is a bit confusing, so I'm not sure if the fuel tanks are 10% smaller, or that the concentration of methanol in the fuel tanks is 10%.
Either way, it's pretty clear that the fuel cell reaction only takes place with very low concentrations of methanol, and my guess is the fuel is going to be a comparitvely dilute mixture of methanol and water.
Let the slaves build them !!!!!

Very safe.
People aren't yelling about how scary and flammable vodka, or any other strong ethanol containing liquid is, but for some reason when they hear the word "methanol" associated with fuel cells it only takes nanoseconds before someone is screaming about safety...
If you live somewhere with cold weather you've probably used diluted methanol in your windshield washer for godssake! Did it explode then?

Does anyone know the practicallities of replacing normal lead acid batteries charged by a generator (on a boat) with methanol fuel cells. The batteries are used for domestic power and charged by generator/engine/wind/solar (in that order) on a sail boat. If I could use silent efficient fuel calls instead (prolly keap one lead acid for engine starting curent and store the solar/wind that I have anyway) and save the wieght space of the genny I would be a happy hamster. Thanks for help :)

However, this particular fuel cell system is probably designed for safety and ease of refilling, and would have a battery or ultracapacitor backup, so the cartridges are probably not refillable on the fly - you have to stop the system, swap the fuel cartridge, and start it up again.
In the future, though, it's not hard to see people taking fuel-cell "generators" on camping trips.
Any sufficiently advanced technology is indistinguishable from a rigged demo
--Andy Finkel (J. Klass?)
The problem with hydrogen is storage. Liquid, gas tight pressure canisters? Methanol is a simple and effective solution to that problem.
You can manufacture methanol from a number of sources, fossil fuels, biological sources, you can even manufacture it from the CO2 in the atmosphere if you have plenty of free energy.

I sure hope that improves. Thats barely better than my current celeron 633 laptop. If better at all. Certainly not at idle.

I dont relish paying a lot of money for a battery that doesnt last any longer than my current one.
Well, then again filling it is a lot quicker than charging a battery.
Ignore me i guess, i must be in a bitching mood.
It's easier to fight for one's principles than to live up to them.
to the Oil Industry.
Laptops and cell phones have already driven batteries to the point where they are useful in cars...
Just think about what the oil industry would do if you could run your electric car on locally made methanol (or ethanol)....
If they're smart, they'll keep this out of the market for as long as possible (watch for exploding fuel-cell laptop horror stories)
But some laptop components are either bog-standard now or come in one of a few formats. Here are the ones that are standard:
The components still specialized are:
> I would rather have smaller laptops than standardised ones.
That's you - but its different strokes for different folks really. Many (most?) people would prefer an open-er laptop specification that could be customized by the system integrator or the end-user. (This is already happening with some system integrators by the way - they purchase laptop barebones kits and build laptops to order)
This would also drive prices down. Of course, the apple's of the laptop world would still have a market share
Also, it states at the end of the article it will take 2-3 years to get to market. It's amazing that the poster of this story can't even read the article
"Toshiba will unveil a prototype DMFC at CeBit next week, but commercialisation of the technology is unlikely to take place until next year"
It says the Intel funded version won't be out 2-3 years.
Sigh. Who can't read the article?

Many users of IBM Thinkpads will know how their Li-Ion batteries get fried after about a month of use.
:-)
They contain monitoring hardware not designed to allow for a laptops unique power needs. This results in the monitors not discharging the Li-ion cells properly, reducing the lifetime of the cells and confusing the thinkpad into thinking the batt is dead when there may be a good 45 mins left!
Buy a new batt for a horrendous price (£45 upwards) and after about a month, it happens again.
All this has created a market for a third party batt, that is actually designed to work with laptops, is cheaper than IBM's "bricks", and can last a reasonable time!
If toshiba start shipping these fuel cells with the form factor(s) of IBM's glorified 1 month bricks then they can be garenteed almost all IBM thinkpad users will buy them!
This also raises the question as to wether IBM have patents on the bricks or if they will use the DMCA to stop toshiba making replacements. Many users probably buy new IBM batts frequently (i don't bother) and because of the 1 month life, this generates quite a revenue for IBM which toshiba could take away.
These issues with batts are not just limited to IBM. Many laptop batt manufactures make the same mistake of using general purpose materials inside laptop batts causing similar problems. IBM however have not admitted to the problem, put it down to overcharging and tell you to order a new one!
Besides, the fuel cells last longer.
Sure it takes me a couple of hours to fully recharge, but that's what a second battery is for, should I need one.
And how heavy is this 2nd battery? And if your battery dies then I suppose you can buy a second one easily enough at the newagents at the airport?
Also, I don't have to refill, nor throw away spent fuel cells. It sounds like manually refueling would be a pain in the arse [for a laptop].
Eh? It will be just like changing batteries in a walkman. Doesn't sound any great hardship to me.
Vehicles using fuel cells sound much more interesting
Do you know how many toxic batteries are disposed of each year? Even rechargable ones have a limited lifespan. I don't think this is any less important than car fuel cells, even if it's less glamerous.
What would be interesting would be a fuel cell laptop that got maybe 24 hours on a "charge".
Fuel cells are ultra-efficient but you can only get out the amount of energy stored in the fuel source. If you want it to last longer, either use a larger refill pack, or cut down the energy usage of the device.
This just seems like gadgetry for its own sake

Ummm- Arent regular batteries MUCH more dangerous exposed to naked flames than methanol. Methanol burns, and gives of relatively harmless substances. L/Ion, NI-Cad, and non-rechargable Batteries tend to explode, revealing some fairly nasty corrosive substances and toxic fumes.

Every program has at least one bug and can be shortened by at least one
instruction -- from which, by induction, one can deduce that every
program can be reduced to one instruction which doesn't work.
