  • The only reason things like this get done is because they <i>can</i>. Why do you think the Unites States and USSR were in the space race? Becuase they new it was possible to leave earth and they thought it was damn cool to beat the other to it. But good thing they didnt nuke the moon, that would just suck.
  • I know. I was pointing out that CmdrTaco didn't follow the advice he gives posters on the page where I type this message and on the story submission page (well, there he actually says (Are you sure you included a URL? Didja test them for typos?))

    But I imagine he may have done it on purpose to lessen the intensity of the slashdot effect on the potato-powered webserver.

  • Stanford University have developed a webserver the size of a matchbox here at the Wearables Lab [stanford.edu]
  • No... I think it was meant as a joke... That "I'd like to clarify that although we are rather (in)famous for potatoes, let me assure you that all our web servers run on 100% electricity." is "informative".

    At least I hope it was a joke...

  • First potatoes, what's next? I'm thinking that a crank-powered web server would be nifty...or maybe windmill powered with a battery charger. I'm seeing a competition for alternative powered web servers.
  • They could have made this project a little simpler (although it wouldn't have been self-contained) if they had used a standard issue netboot ROM and booted the thing across the network. Coulda mounted the filesystem via NFS and had a hell of a lot more space to play with, too...

    Bicycle pedal, thats right, right under the desk. Geeks can surf and burn calories at the same time.

    Reloving door, attach a generator to a busy building and watch the electrons dance. Maybe even a webcam so we can watch our unwitting hamster wheelers.

    Solar, but with no batteries so you know the weather is crappy if the server went down.

    Mice balls, a tiny generator inside every mouse. Sure it'll be much harder to roll on the desk but you'll be providing a valuable service.

    Mandatory "donations," want to get in or out of the bathroom? Turn a crank for a while to make x amount of power before the door will unlock. Raise productivity by removing air fresheners and serving slightly spoiled food in the cafeteria.

  • Now this is trully green powerd computing.

    Hate to tell you this, but over here in Europe potatoes are *not* green. They're brown with maybe some green bits growing out of them, but that's all. Overal, they are definitely not green.
  • Please take a look at the photos in the gallery. I am not sure, but shouldn't the power cables on the motherboard be connected the other way round?
  • By virtue of being /.'ed, the low powered potato server will now be overloaded. They did warn against too many accessing at once on the page, but my guess is that everyone at slashdot will go ahead and connect to the potato server anyway, overloading its small potato power capacity. Oh well...I thought it was pretty cool.


    --------------------------------------------
  • If I got bored, I would see if I could improve the performance of the potato-powered battery by inventing my own.

    Here's what I would like to try:

    5 Copper rod electrodes
    5 Zinc rod electrodes
    5 polystyrene cups
    6 wires with alligator clips each end ("alligator wires")
    1 kilogram of washed potatoes

    Tools:

    Kitchen blender
    Steel wool

    Instructions:

    * Cut the unpeeled raw potatoes into large chunks and place in blender.
    * Blend until smooth.
    * Place potato mixture into the polystyrene cups, distributing evenly.
    * Clean electrodes with steel wool. This removes the oxides.
    * Place one copper and one zinc electrode into each cup.
    * Connect the cups together in series by connecting copper electrodes from one cup to a zinc electrode from the next with four of the alligator wires.
    * Connect the remaining two alligator wires to the free ends.

    I would draw a diagram here, but the <PRE> tag is not allowed HTML.

    This should give a battery with an output of 7.5 volts. I have no idea of the current, though - the only way of knowing would be to try it.

  • Should we be even in the teensiest bit surprised that it got slashdotted?
  • Barring that it is a very strange motherboard, or a 'unique' power supply, wires should be black to black in general.

    Could also be a non-operational mockup before it got going -- ? -- hope it is, would be awfully spiffy to have a potato powered server.

  • I just read the f ollowing article [bloomberg.com] that says that McDonald's is cutting its French fry cooking time from 210 to 65 seconds, but wouldn't provide any details about their new system.

    This web server explains alot...

  • Now if they powered it with a single spud that would be something. Each Zn/Cu cell is 1.5V if I remember my high school chemistry. So 5 sets of electrodes in 5 spuds gives them 7.5 volts to play around with. Now if they had taken a Rio 500, converted it, and powered it with a single spud and then taken the output through the USB port to a hub THAT would habe been an accomplishment.

    However, as it is, my hat is indeed off to them anyway. May their web server spudder along for a long time to come...

  • Beowulf [alcyone.com] is set in 6th-Century Scandinavia [slashdot.org]. Potatoes [cipotato.org] originated in the Andes [ic.gc.ca] and were brought to the new world from Peru by the Spanish conquistatdores in the 1500s/1600s. So Beowulf would have been dead about a thousand years before he could get a potato, and probably a while longer before he could get any French Fries...


    Dan Quayle probably couldn't spell Beowulf either...

  • I've seen on the Discovery Channel that a guy made little hand crank generators to power small devices. These things were great for running laptops and such. Crank for a min or two, power yer laptop for 5 min. Not great, but if you are in dire straits, it'll getcha by. It was designed for emergency situations for flashlights, and for guys out in the jungle :) I wish that I knew who it was, and I was waiting for consumer devices based on it, but it's been a year or more sinceI saw it, so I've kinda given up :)
  • now im gonna be getting emails like this: o"ur web server will be down tomorrow to replace the potato's. we will be installing potato's from idaho which should last us another week"
  • Actually, it probably isn't. Right now there's still a broken link in the story.

  • ...I'd bet my left nut that it isn't. Forgive me if I'm being obtuse and the people here who are apparently taking it seriously really aren't.

    Potato, lemon and other vegetable-electrolyte electrochemical cells are, even with big electrodes, only good for a few milliamps per cell. With the nail-sized electrodes shown here, one Cu/Zn electrode pair per spud, and six or seven spuds, they could manage 0.8V (barely) per cell, and 1mA on a very very good day indeed. Probably much less - "high-current" spud cells do it, I think, with many pairs of electrodes in close proximity.

    Charitably, this setup could do 5.6V at 1mA, or 0.8V at 7mA, or intermediate values with series/parallel combinations. Any way you slice it, it's less than six milliwatts. Let's give 'em the benefit of the doubt and say 6mW is it.

    You can light an LED with that much power. That's about all you can do. Running any sort of PC hardware - desktop or mobile - from 6mW is ridiculous. Wristwatch, yes. More than enough juice. 80386, no way in hell.

    If the displayed device actually is the server you're connecting to (or not, depending on slashdotting...), then the "Power Converter/Regulator" is, one way or another, a regular power supply, and the spuds connect to nothing.

  • Actually, the critical resource here is probably
    not the potato itself, but the zinc on the nail
    getting oxidized. You should be able to reuse the potato as long as you keep changing nails.

  • But I'd really like to know: do potatos taste as good when they've had all their electricity taken out?

    Probably not. After use, you'll have oxides and salts of zinc and copper in your potato, which probably won't taste very good.

    The potato is actually just acting as an electrolyte and semipermeable membrane - the power comes from the zinc and copper.

    There's also the possiblity of sponsorship here. If it were powered by burgers instead of fries, they could put up one of those 'one billion served' banners.

    A neat idea, but it probably wouldn't work. Burger grease wouldn't make a very good electrolyte.
  • to link that webserver on a chip with this potato power concept. A whole computer isnt going to last too long just of tatties, whereas one of those process controllers takes basically ziltch power. Relatively.

    The citric acid is a much better electrolyte. Although I really prefer to power my servers with a large bank of "6-cent batteries". Just take a nickel and a penny, soak some paper in vinegar, and put the paper between the two coins. Instant electricity.

  • Last year I saw a windmill in the Flathead valley about 15 miles North of Missoula. I always thought it would be interesting to put a few servers in there, set up a wireless optical internet link, and have the worlds largest wind-powered ISP.

  • This is very normal.. it's as good as anywhere else, and is a convenient place to put a boot rom.
    It doesn't have anything directly to do with the network card per-se, only that the card provides memory addressing and a socket for a rom.

    If the motherboard had a boot rom socket, they could use that...
  • by mindstrm (20013) on Sunday May 21 2000, @12:00PM (#1057930)
    Recall, it's not the potato that does the powering.. the potato only acts as an electrolyte.
    It's the copper/zinc electrodes that are really used up, and their size (as well as how good the electrolyte is) determines how much current can be drawn.

    So.. a piece of paper soaked in vinegar could work as well as a potato... if not much better.
  • This gives "server farm" a whole new meaning...

  • I'd like to clarify that although we are rather (in)famous for potatoes, let me assure you that all our web servers run on 100% electricity.

  • We've slashdotted major websites
    We've slashdotted a Commodore 64-based Webserver
    We've slashdotted a VEGETABLE

    What's next? How do you top a vegetable? Slashdotting a webserver running on an actual living brain is all I can think of...
  • by Anonymous Coward
    Powering a computer from a couple of potatoes is not possible. The current you can get from a potato is just a few microamps which is just enough to power a digital watch. From my experience, a 386 motherboard without any expansion cards installed takes 500 milliamps at 5V, which is 2.5 Watts. A digital watch takes 1 microamp at 1.5V. I think that the 'power converter/regulator' box is either empty or contains a battery to power the motherboard.
  • ...while we're being slashdotted. We're in the process of moving to a better co-lo facility, on the produce isle.
