Fuel Cells for Laptops Due Next Week 186

prostoalex writes "AVC and Antig Technology will demo a production-ready fuel cell for laptops next week on CeBIT trade show. According to PC Magazine, 'the CD-ROM size fuel cell will fit within the media bay of a notebook PC, replacing the drive with additional battery power.' The fuel cell battery will last 8 hours."

      I don't get it. Practically every manufacturer uses a different form factor for CD bays, and many more than one. How hard is it going to be to find one of these for your favorite notebook? What about notebooks that don't have swapable bays?

      A better option would be to make a power "brick" with a DC output and a number of tips for popular notebooks, much as currently done for universal power supplies. You could then make a single device that works with a lot more notebooks, and have more power available as it's not constrained to fit into a particular form factor.

        What decade are you living in? Most all laptops these days use the standard slimline cd-rom. They just have a different front bezel attached.
        • "They just have a different front bezel attached."

          Precisely. Often permanently attached. And not "all" support an extra battery at that location. And, of course, there are notebooks and sub-notebooks without CD-ROM bays at all. And Macs with slot-loading, non-removeable drives. Or Panasonic Toughbooks with their top-loading drives. Or...

          Never mind. It's apparent that "most all" of the notebooks with which you're personally familiar adequately represent the entire notebook universe.

Laptops with such drive bays are so popular that you can buy slimline notebook drives all over the place, sold by manufacturer name ("LG"), not notebook brand. Many laptops work fine with a the drive's built in bezel, though.

          And while we're on the subject, "most all" notebooks these days use a power brick to supply DC power. A move which also allows them to easily use 12v DC car chargers and plug into airline power outlets. In fact, I dare say that more notebooks do that than they use a specific CD/DVD drive form factor... which is why I made the suggestion in the first place.

      I am amazed that they let you fly with lithium-ion batteries. A lithium-ion (or lithium polymer) battery is basically a bomb with a bit of electronics trying to persuade it that it's really a battery.

      On a lighter note, have you ever been asked at an airport if you are carrying anything that can be used as a weapon? What do they imagine you might be carrying that can't be used as a weapon?

    • Well, for one, this lasts you most of your workday. 2nd, once your laptop uses smaller conventional batteries and frees up more space for fuel cell technology, you should see it approach 18 hours or so, which is literally a day worth, if you sleep the other 6 hours. Not to mention that if one pack is done, you can go exchange it for a full one at the local kiosk, vending machine, or post office.

    Something tells me that the initial price of these fuel cells is going to exceed the price of the laptop itself. In fact, I'll bet it'll be cheaper for me to buy a car batter, an inverter, and a sherpa to carry them while he follows me everywhere. :)
    • dude, you don't need an inverter, you just need a DC to DC convertor and the appropriate plug on the end of the lead. Why convert to AC just to plug the laptop AC adaptor into it... get hold of a Cigar lighter socket (and some leads to hook up to the battery with) and the appropriate Car DC adaptor to run your laptop from.
      • Most computer PSU's actually are just DC-DC converters. They take the incoming AC, rectify it and use it to charge a capacitor (typically to around 170VDC, but they will usually run happily at lower voltage, check the specs for the PSU for the rating).

        This isn't much help if you don't have a source of fairly high voltage DC available, but if you feel like putting some 12v cells in series you can directly power a computer PSU with it.

    If true, I'd buy it.

    My last laptop (a Dell Inspiron 8000) I kept two batteries in (it was a three spindle notebook). This increased the weight, but gave me over three hours of battery life with normal use (it was a desktop replacement that just loved to eat batteries). I would gladly replace one in that notebook with one of these for the extra battery life (if I still had it).

    My currently laptop is a Apple PowerBook (15", Feb 2005 model). I'm not sure it would have the room necessary for one of these to replace the standard battery, but I would gladly do it (I currently get 3 hours of use, or about 45 min if I run a full-on 3D game with the laptop in "high performance" mode).

    I would be much more interested if it was a closed system that could recharge it's self (like a fuel-cell could be set up). That said, it's 45w of power and almost 4 pounds. My current battery is 46 watts and less than 1.8 pounds. And I know the newer PowerBooks and MacBook Pros have better batteries than mine.

    3 more watts, double the weight. How will that give me 8 hours of battery life? I'm skeptical. Maybe in an ultra-light notebook with a slow processor doing word processing.

    Still, at least someone is about to market something other than a "normal" battery.

    • 3 more watts, double the weight. How will that give me 8 hours of battery life?

      Er, I'm not sure what you're trying to say here. You do realize that watts are a measure of energy output per second rather than total energy?

    I think it would still be more convenient to simply plug the laptop into the wall, a car outlet, or even a solar array for a recharge. If you're in the absolute middle of nowhere, you could carry an extra battery or two and it probably wouldn't be much more volume/weight than a pack of methanol containers. On top of that, hotel rooms, conference rooms, coffee shops and other places I use my laptop don't have methanol dispensers, but almost all of them have plenty of free electricity.

    Besides, 8 hours is not that huge of an improvement over batteries. Fuel cells seem to have promise, but I won't be switching until I can run a laptop for days at a time.

    If history is any guide, it'll take at least _two_ weeks.

    especially since by the time this crap comes out, intel will have it's ultra low power core chips out (45 nm) for laptops that are supposed to get 8 hours or more battery life (late 06)
    • And, presumably, the fuel cell would still allow machines with those chips to run much longer between recharging, since the merit of the technology is greater power to volume ratios.
