Laptop Fuel Cells Coming Soon 181

tomsastroblog writes "Soon laptop batteries could last all day and be recharged from a cartridge. BBC News has a piece on fuel cells as laptop batteries, and what their adoption could mean for laptop usage." From the article: "At the Cebit technology fair in Hanover, Taiwanese hi-tech firm Antig said its fuel cells should be on the shelves of computer shops by early 2007. The first versions of the methanol-using units should keep a laptop going for up to nine hours. Fuel cell technology got a boost recently when international air flight regulators changed rules that banned passengers from carrying flammable methanol onto aircraft."

    I especially like the ability for them to fit into existing laptops (in the media bay), rather than only working with new, specially-designed laptops. Overall it sounds great, however expensive. It'd probably be years before they can get the price down to a reasonable level. Either way, it might not be a bad idea to go invest in fuel cell stocks now. :)

      • I think that most laptop media bays are the same size, while most battery bays are different size. I read somewhere on a support forum that basically all laptop optical drives are the same size, with a different bezel on the end of the tray. If that's so, then this will be a lot cheaper to produce.

        That said, I would definitely prefer it in the battery bay.

      As for the "giant can of Zippo," yes, we would all like to have a fuel cell battery that lasts for a week and fits right into the old battery slot, but cut them a little slack. It's a new thing and it's bound to improve and the fact that there may be a laptop fuel cell at all in the near future is pretty interesting.

      The reason I'm selling my old laptop on eBay right now is that the battery life is horrid. Now of course 1.5 hours is on the low end of bad nowadays, but I'm really looking for something that should last for a full day of school. While I may not be in some field of flowers, longer battery life is a must for me. I'd say it's just as important as, if not more important than the price of the thing. I don't need a powerhouse (I've got my desktop for that) but being able to get some work done on the go is extremely important for me. I know there are some units available rated for six hours, but that's probably time spent just sitting at the desktop.... I need to at least be able to have a word processor or spreadsheet open. I'd imagine every other soon-to-be college student in the world is looking for that at the very least, not to mention most people that are looking for a laptop that's not to act as a DTR.

      Most people wouldn't care whether it's a micro-fusion reactor in their laptop or a flock of nano-gerbils on micro-running-wheels as long as they get good life out of the thing. Well I suppose PETA would take some offense to the latter, but they don't need to know. Point being, for most people, having a laptop is all about mobility, and for the most part battery life is the main issue that comes into play, probably with network access coming in next.

      A lot of people keep saying this, but it just doesn't hold true!

      First of all, methanol doesn't pose nearly the health risk most people believe. As someone with a solid non-practitioner background in both chemistry and pharmacology, I would play with methanol over toner or ink any day... Additionally, the breakdown products the the electrolyte in Li-ion batteries makes methanol exposure look like a cool drink of mountain water by comparison (for an idea, the most common counts as a chemical WMD in a different context).

      Second, methanol doesn't pose nearly the fire/explosion risk most people believe. The Li-ion batteries we use now pose a FAR greater risk of explosion, and as for fire, if you take the same precautions you would when refueling your car (with yet another far more flamable/explosive liquid), you have nothing to worry about.

      Third, refilling... Aside from the previously-mentioned toxicity of ink and toner, methanol evaporates cleanly. So if you spill a few drops, you can just let them evaporate rather than permanantly staining yourself, your table, your laptop, your carpet, your dog, and seemingly anything else even in sight of the ink refill kit.


      The biggest complaint about the idea of using fuel cells over a rechargeable battery in laptops comes from the UPS-factor. Even an all-but-dead laptop battery will let it stay up (assuming you have it on AC) through a short power outage, or to move to another outlet, or to quickly reinsert the plug your cat pulled out, etc. Running on a fuel cell, all those advantages disappear unless you use the fuel cell as your primary power source, which could get expensive over time (despite methanol's low cost, AC power costs a hell of a lot less).
      • I'm not saying that fuel cels are dangerous. I'm one of those guys who wouldn't mind nuclear powered cars. I'm saying that I don't like dealing with ink refil kits, and I don't think fuel cell refil kits would be any more fun.

    Today most laptops are just dragged between electric outlets since they wont go for more than a couple of hours without recharging. Having nine hours worth of computer time changes the way you can use a laptop in a pretty significant way. From being used as a portable desktop you can use it as a really portable computer, taking it whereever you go without running amok for a piglets nose.

      I was thinking before that I'd really love to be able to have a laptop with 9 hours of battery life - something I could use in the departure lounge waiting for my transatlantic flight (someone else always gets the seats near the power sockets before me) and then use on a 7hr flight without worrying about battery life.

      That's why I got the IBM X41 - I have a 7 cell extra-life battery plugged into the back, and a second slim battery that plugs onto the base of the laptop. The two together give me between 7 and 10 hours of battery life, depending on what I'm doing (usually programming, so I'm not a 'power' user).

      Buying the IBM was one of the best decisions I've ever made (no connection to the company, or to Levono who now own their PC business). After my recent flight from London Heathrow to Toronto I had 1.5hrs of battery life left on the machine when I shut it down as we were preparing to land.
       
      So... this wasn't that expensive - the laptop and all batteries were less than 1000GBP including tax... is there really a genuine need for fuel cells?

      The reason fuel cells are much hyped, and preferred over batteries is that they use liquids to produce the electricity. This means that the size of the reaction interface is decoupled from the energy storage medium (whereas in a battery, they are intimately linked [normally]).

      So, the size of the reaction interface determines the power that you can get out of the fuel cell, and the size of the energy reservoir determines how long it will last.

      A laptop draws, what, 100 watts peak? A car with an 80 hp engine is at 60 kW - 600 times more. A fuel cell big enough to power that would be prohibitive in cost. Not to mention, the fuel cell will degrade with time - impurities in the fuel, and (if it's a polymer cell), degradation in the polymer itself.

      Next point is the fuel medium. The energy density of methanol is less than gasoline, at about 22MJ/kg vs 45MJ/kg for gasoline. So, assuming comparable fuel efficency with the internal combustion + mechanical drive vs fuel cell + motors, you'd need twice as much fuel.

      There are no good fuel cells that operate on gasoline - the more complex the hydrocarbon, the harder it is to build a fuel cell. Couple that with the way the sulpher tends to kill fuel cells, and it's not feasable (low sulpher gasoline is available - have you ever seen guarenteed no sulpher gasoline?)

      So, it would cost more, and you'd only get half the distance on a single tank of methanol. Assuming that you can get the methanol. The whole fuel distribution problem is a seperate case.

      All the numbers here are conservative - I'm sure my powerbook draws significantly less than 100W, 80 hp is at the low end for a car - I believe 100hp is more typical. The laptop fuel cells don't use pure methanol, it's methanol and water, further reducing the energy density.
    • So if they can make fuel cells for ficken *laptops* why can't they do the same thing for cars?

    Just about every year since the mid-90s Internet boom we hear that fuel cells will be available Real Soon Now. They're a really cool idea, you obviously want them, and I hear that they're packaging them with a free copy of Duke Nukem Forever....

    How much energy can we pack into a small package before we need to start treating it like thermite? If we're putting many watt-hours into a cartridge and it malfunctions, could it, for example, end up melting its way through the cabin floor and skin (and the fuel lines) of an aircraft?
  • Is why isn't this being announced by an American company?
  • Anyway - I'm just tired of hearing this tired, recycled bull about "laptop fuel cells" - I was on board with it until the 2nd story came out around the time cells hyped in the first article were supposed to see market...

    It seems like the "this will be on the shelves by" date has getting incremented by 12 to 18 months each time the story sees daylight since the I first started seeing it in - what, 2003? 2004?

    The point about it that disrupts the "willfull suspension of disbelief" that I typically rely

  • I've actually been involved in the preliminary designs of a small very powerful wearable computer, and we looked really hard at a fuel-cell solution - from Antig, no less. The real turn-off was not risk of fire or anything (this can be handled), but the fact that for every 10W of electrical power they generate 12-15W of heat. It's already difficult to get rid of ~25W from the electronics in a lunchbox sized device to be worn on the body. Now imagine adding ~35W of heat to generate the 25W - no thanks. I hop

No spitting on the Bus! Thank you, The Mgt.
