NEC Unveils Methanol-Fueled Laptop 363

genericplacebo writes "Japanese computer giant NEC Corp. Monday revealed a prototype of a laptop computer that runs on a methanol fuel cell instead of a rechargeable battery, and said it will start selling it next year. NEC initially plans to introduce a computer with a fuel-cell system able to run for five consecutive hours on a single cartridge of methanol fuel, but also plans to make a PC within two years that can run continuously for as long as 40 hours."

        Seems to me that the proper approach would be to make a laptop that can run on either a battery or a fuel cell. If you're running near AC, run on battery and recharge occasionally. If you're on a 10hr flight or something and they havn't been thoughful enough to have accessory plugs on the plane for laptops and such, or if you're on safari in the middle of Africa, switch to the fuel cell.

        The issue I'm worried about is that the laptop/fuel cell industry will to do what printer manufacturers did for the printer. In other words, make the fuel cell hardware cheap and affordable and price-fix the actual fuel refill components as high as possible to maximize profits. The old razor blade pricing scheme.

        From what I understand of fuel cells, besides requiring the fuel itself which is rather cheap, it requires a rather expensive (and no-doubt proprietary) catalyst component (platinum?) which sort of throws the "refill at home" idea out.

        Maybe you could get 5x methanol refills before replacing the catalyst or something, but I'm waiting to see what the pricing of the fuel technology will be before jumping onboard.

          By definition a catalyst is not consumed in the reaction, and so theoretically, it should not be necessary to replace it for a very long time.

          As far as I understood, the whole advantage of fuel cell based laptops was you could simply open a spout and pour more fuel into it, like a camp stove. If, instead, you must buy proprietary cartridges like printers, I don't see why people would opt for a fuel cell based computer rather than a conventional rechargeable battery. In fact, the proprietary scheme you described above would be rather more like a laptop which runs on non-rechargeable batteries! I can't imagine anyone buying such a thing.

      • The fuel cell outputs current, ergo "transforming it" takes a switching power supply - just like the laptop already has. And even a switcher for a home PC doesn't weigh more than a few pounds; take it out of the box and it's not likely to weigh more than a pound or two. And that's for a home unit.

      The point with this is that currently you cannot buy one. This is (one of?) the first methanol fuel cells laptops. Give it a year (frankly, year an a half given typical engineering development time estimates), then, and only then, will you have a choice.

      Now, all that aside, I'd rather have the fuel cell system. Let's assume that they weigh the same, and run for a similar time on one charge, like you suggest. With a methanol fuel cell, a replacement charge will weight, what, 100g, cost around a dollar or two, and be field recharageable. This means that I can carry enough fuel to last a day of use without falling over. To do that same trick with batteries, you'd have to carry 5 spare batteries, each costing, what, 50-75 dollars [0], and weigh the thick end of a kilogram each. Not only that, but spare batteries have an interenal discharge rate, meaning that they cannot be stored indefinitly (It's about a month for NiCd, less for NiMh, dunno about Li technologies).

      Granted, if you break a methanol cartridge, then it's not pleasant stuff. Mind you, nethers the contents of your typical battery.

      The trade off is then you can carry much more fuel, but you'll need to find a specialist to get more, vs the limited fuel and easy refilling for battery technologies.

      Once the runtime of a single cartridge of methanol gets up, to me that's a no brainer. YMMV

        Methanol is like isoproponol. It'll evaporate fairly quickly, shouldn't damage your laptop's plastic much, etc. Unlike IPA, it can be absorbed through the skin and causes nerve damage, but it requires a fair amount for any significant effect. Basically, if you break a refill cartridge, wipe your hands then pick up the spill, and that's pretty much it. Only people like me who work with it all the time really need to be worried about exposure.

Then when your off the plane you can put your battery back in and go back to using your standard convenient energy source; ie the wall.

      Guess what? Nobody ever talks about it, but Lithium Ion batteries have a VERY finite lifetime; a FEW(very few) hundred discharge-recharge cycles; every time you discharge the battery, and the more you discharge it- the more of the battery you permanently destroy.

      Companies that make these Lithium Ion cells(no foolin', that square battery contains a whole bunch of cells that are almost exactly AA size) won't sell them to you, of course- why? Because if you overload them, they catch on fire pretty handily, so you have to be a "certified" "solution provider" lest you blow yourself up. Mind you, the battery companies could install thermal/current fuses in the batteries, but they don't want to, because it conveniently lets them control the market, and gives them an avenue of escape if a pack for some camcorder or digicam has serious problems- they can point the finger at that company.

      So, even though Panasonic still makes the cell used by my Powerbook Lombard, and even though you cannot buy new Lombard/Pismo batteries(they're no longer made, period), I can't fix my lombard's battery.

    Methanol (CH303) is the simplest alcohol, containing one carbon atom. It is a colorless, tasteless liquid with a very faint odor and is commonly known as "wood alcohol."

    Methanol is one of a number of fuels that could substitute for gasoline or diesel fuel in passenger cars, light trucks, and heavy-duty trucks and buses.

    It's physical and chemical characteristics result in several inherent advantages as an automotive (or laptop) :) fuel:

    Emissions from methanol engines/laptops are low in reactive hydrocarbons (which form smog) and in toxic compounds. Methanol-fueled trucks and buses emit almost no particulate matter (which cause smoke and odor, and can also be carcinogenic), and much less nitrogen oxides than their diesel-fueled counterparts.

    It can be manufactured from a variety of carbon-based feedstocks such as natural gas, coal, and biomass (e.g., wood). Use of methanol would diversify the country's fuel supply and reduce its dependence on imported petroleum.

    Methanol is much less flammable than gasoline and results in less severe fires when it does ignite.

    It also is a high-octane fuel that offers excellent acceleration and vehicle power.

    With economies of scale, methanol could be produced, distributed, and sold to consumers at prices competitive with gasoline.

    Because of its outstanding performance and fire safety characteristics, methanol is the only fuel used in Indianapolis-type race cars. Following a series of methanol vehicle development and demonstration programs throughout the 1980's, a limited number of methanol passenger cars and buses are now commercially available. There are approximately 14,000 methanol passenger cars in use, mostly in Federal and private fleets, and about 400 methanol buses in daily operation, mostly in California.

    Methanol is used in a number of consumer products, including paint strippers, duplicator fluid, model airplane fuel, and dry gas. Most windshield washer fluids are 50 percent methanol.

    Already 3 posters that prefer batteries over fuel cell powered laptops. Well, I can't say I disagree that batteries are better, but there are exceptions. There are places where charging a laptop is not possible.

    I'm always going to a little coffee shop where the only power outlet is all the way in the back, so I can't recharge my battery. Now I have a laptop that lasts for about 4 hours between charges, but I can't always show up there with a fully charged battery. Why do I keep going there? Somebody upstai

    I see most people scoff at the idea of buying fuel cell cartridges for their laptop. Well, then this laptop isn't for you -- you have easy access to electricity. This is revolutionary because now you have a portable computer ANYWHERE, and you can recharge it with a little cartridge instead of lugging a huge generator with you.

    Hello military and 3rd world applications. I can see a brand new market -- deploy some these bad boys, set up a wireless access point, and you have an instant internet community with no other power infrastructure.

    This is another step in getting computing power to the third world and closing the digital divide.
    • it's a step toward freeing us all from the grid. There are plenty of people in the US who have to generate their own power because they live halfway up a mountain or ten miles from the nearest grid connection. Once this evolves into a technology capable of supplying higher currents then we can be rid of internal combustion generators in off-grid applications.

      Of course, if the catalyst isn't capable of being "cleaned" or efficiently replaced then it's all just so much more useless crap...

  • Fuel cells are certainly a promising technology, and it is no suprise that they will eventually make their way into consumer devices. NEC apparently will offer this model as early as next year, but a few details are missing from the article.

    How much space does the fuel cartridge take up compared with an average laptop battery? How much does the fuel cartridge weigh compared with an average laptop battery? How much is the initial fuel cell cost compared with an average laptop battery? How much is the i

    Methanol is a very potent neurotoxin, is relatively volatile, and has a much lower energy storage density than ethanol. Ethanol is relatively non-toxic by comparison (unless you imbibe very heavily), is less volatile, contains much more energy per mass or volume unit, and can be made and distilled to an acceptable grade by just about anyone, anywhere.

  • NEC claims 5 hr battery life. those who want this battery life can possibly buy transmeta based computer. you get lower speed and better battery life. how many of you would want Lithium battery and 1 GHz computer vs fuel cell and 2 GHz computer, if they both have same battery life and same cost? i would go with former.
  • Reckon I'll need a bigger screen for when I've emptied the fuel cell.

  • Does anyone know what the by-rpoducts of the reaction would be? I'm no chemist, but I'm guessing water, carbon dioxide, and probably heat.
    I don't really mind the CO2, but water and more heat with my laptop? I dunno....

    Of course I'm guessing about the reaction and leftovers. Can someone tell me if I'm right or wrong?

      Direct Methanol Fuel Cells (DMFC)

      The direct methanol fuel cell is a variant of the PEM fuel cellwhich uses methanol directly without prior reforming. The methanol is converted to carbon dioxide and hydrogen at the anode. The hydrogen then goes on to react with oxygen as in a standard PEM fuel cell.

      Anode Reaction: CH3OH+ H2OCO2 + 6H+ + 6e-

      Cathode Reaction: 3/2O2 + 6H+ + 6e- 3H2O

      Cell Reaction: CH3OH+ 3/2O2CO2 + 2H2O

      These cells are expected to operate at around 120C, which is slightly higher than the standard PEM fuel cell, and give efficiencies of around 40 per cent. One drawback is that the low temperature conversion of methanol to hydrogen and carbon dioxide needs a larger quantity of platinum catalyst than in conventional PEM cells. This increased cost is, however, expected to be more than outweighed by the convenience of using liquid fuel and the ability to function without a reforming unit. The technology behind direct methanol fuel cells is still in the early stages of development but it has been successfully demonstrated powering mobile phones and laptop computers, potential target end uses in future years.
  • Do fuel cells produce gases? Even if they don't under normal circumstances, is it possible for a defective one to produce gases?

    The reason I ask is - a small leak, and a spark, and you've got more to worry about than spilling the expresso on the keyboard.

    Until its proven (and I don't see people combusting at the local Starbucks), I will have a fallback plan:

    1. Get one of those heavy duty backup storage batteries used to jumpstart automobiles (these have 'cigarette lighter' style female plugs on them).

    Thank god it's not fueled by ethanol.

    If it were fueled by ethanol I'd always come back to the two choices ... Two more hours of laptop time, or get drunk.

    I'm surprised at how many slashdotters are suspicious about this technology.

    Methanol is *extremely* cheap to make. We are talking about buying a gallon or two for less than a dollar. Yes, it is flammable but not like gasoline. There isn't a risk of explosion. Do you ever worry about your lighter exploding in your pocket? Yes, its poisonous but only if you drink it. Ever drink glass cleaner or windshield wiper fluid? Didn't think so. Its sort of like that. Its much worse to drink gasoline (we use it all the time in cars and how many people are poisoned by that?) and opening a laptop Lithium-ion or Nicad battery and eating the contents is far worse.

    I'm surprised at how happy people are with laptop batter performance these days. You are lucky to get 4 hours, especially if the battery is old. YOu can get more, but the batteries get very heavy! Methanol, on the other hand, is quite light.
