Music Fan Charges iPod With an Onion

Music fan Owen Louis was so concerned about the amount of energy used up by his iPod, that he figured out a way of charging it up … with nothing more than an onion.

Louis, 21, from Portsmouth in the UK, makes two holes in an onion, before soaking it in an everyday energy drink and connecting it to his MP3 via a standard USB cable. Incredibly, the technique (video) enables him to charge his iPod for a full hour. According to Louis, “A friend showed me the experiment as a laugh but I thought it was the greatest thing I have ever seen, and do it religiously every day.”

Speaking about the technique, Phil Stubbles, a physics lecturer from Hampshire said that almost all vegetables could power iPods because they contain ions which react with energy drinks to create a charge. “The only problem is you have no control over how long it may work for … and it can be smelly,” he added.

Author’s Note – Since it first hit the newswires, this story has been causing something of a stir in the blogosphere.  First came itwire, claiming that the story is a hoax. Then, a number of other blogs, including macworlduk, shiny shiny and digitalspy ran with the story claiming it was true (or at least open to debate). However, according to the Guardian (25 November), it appears that the basic science behind the idea is correct, but that this particular technique is a hoax. The article quotes Jon Edwards of the UK Royal Society of Chemistry (no less), who says “The science behind the idea isn’t bad – you can generate an electric current from vegetables – but the video is a hoax.”  He explains that it can’t work because you need two electrodes to provide a reaction and a reason for an electric current to flow.

Out of interest, do any readers have any more technical information on this? Or perhaps you’ve tried the experiment yourself? If so, feel free to get involved and make a comment.

    I’m not sure why this is news or why this would be posted. This wouldn’t become anything widespread, and if it was, it would actually be a bad thing. It takes a lot of energy to produce food so it would be more efficient to power an iPod the traditional way — through an outlet or USB while on a computer — than through an onion and energy drink.

    to bad this gut has never seen mythbusters.

  3. tom Says:

    it’s a hoax.. >_>

  4. Scott_T Says:

    Umm, I’m pretty sure this is a hoax.

  5. Nick Says:

    …the only other problem is that it uses far more energy to create the energy drink and grow the onion than you get out of it to charge your iPod. Interesting experiment, though, that I have seen many times.

  6. Erik Says:

    This is a hoax … I hope it was meant as such by you guys! The same people that gave you this video show you how to power a TV with an AAA Battery …

    Even if it did create enough power to charge the ipod, sticking the USB plug in to the onion would short out any benefits provided.

  7. Lake Says:

    Even if you could do that the amount of co2 used in creating the energy drink and for shipping the energy drink and onion would far out way the little amount of energy an ipod uses.

  8. Jack Says:

    An energy drink and an onion costs more than just buying batteries. The batteries last longer too.

  9. Steve Says:

    I would propose removing this article.

  10. zero-kill Says:

    Not worth it.

  11. Uncle B Says:

    Potatoes with zinc and copper strips can be fashioned into a “battery” powerful enough to run a LED light! Check the net for more examples! Good news for off-griders, emergency power for your cell phone is only a potato away! I prefer solar cells myself, but small crank up emergency radios and lights will work too! Don’t automatically think plug in and entitlement, think outside the box now and then!

  12. Dwindle Says:

    What an incredible waste of an otherwise useful onion.

  13. EyesWideOpen Says:

    This is quite obviously a hoax, but it’s a riot that they got so many people sucked in on it. heh-heh

    You might want to research this a bit more…or not…either way, you’ve been had!

  14. matt Says:

    so he goes out and wastes like 2 or 3 dollars every day to charge his ipod? that shit adds up

  15. vacation packages all inclusive Says:

    Quite amazing this way we are going to save a lot of electricty.

  16. Reid Says:

    I’ve tried it before but it did not work for me…

  17. Homer Sipsoy Says:

    Nice reporting… an article based on a that is a proven hoax video that is more than a year old…

  18. Dan Says:

    Mythbusters takes this one on: http://dsc.discovery.com/videos/mythbusters-ionion.html

    Seriously, though, we’ve all seen a potato-powered clock, but for a technology website not to put a little thought into this before posting it as factual speaks poorly of the author and the site’s editorial staff.

  19. Ariel Schwartz Says:

    @Dan – Thanks for your comment. As you can see, we posted a note at the bottom of the post discussing the factual nature of the onion-powered iPod. As far as “putting thought into this”, reputable news sources from Macworld to the UK Guardian have reported the story.

  20. Michael Says:

    I believe it’s true. I watched something one youtube about this over a year ago (I’m surprised it just now got on digg). It makes sense because to me because iPods have lithium ion batteries. I think it’d be neat to try once but the onions and Gatorade is gonna add up if you charge your iPod everyday(And make you cry!)I invested my money in an iPod charger ; )

  21. Kenny Says:

    This is a hoax for sure. If you arent convinced, check out some of the other videos that the same authors have put out.

    On the other hand, theoretically, an onion in gatoraide could be turned into a battery if a zinc lead and copper lead were put in. This is called a galvanic cell (look it up). Similarly, people make batteries out of lemons or potatoes with no need for gatoraide using this technique.

    Despite the theoretical possibilities, nothing would happen if you followed the video instructions perfectly, except perhaps draining your ipod battery with a short circuit and getting your cord sticky.

  22. marshoutlaw Says:

    does he know how much energy it takes to grow an onion and produce an energy drink? what a waste of resources.

  23. lll Says:

    Same idea as potato alarm clock experiment done in grade school. Can’t vouch for it on my own, but seems plausible enough. My concern would be whether it produces enough voltage/current.

  24. Brian Says:

    This will not work because ions only travel from an area of greater charge to an area of lesser charge; when plugging in the USB cable to the top of the onion, the correct pins in the USB cable cannot attach to the correct areas of greater or lesser charge in the onion.

    And, just because there are electrolytes inside the onion does not mean that they carry the necessary voltage/amperage for the device to begin charging anyway.

  25. Earl Co Says:

    You guys should get with the times. I saw this on Instructables last year. Nothing new. Amazing anyways.

  26. Steve Says:

    Or we could just start burning trees to produce electricity! Trees would be considered alternative energy. We could just cut down all the forests and burn them, then, grow onions on the newly formed farmland to charge our ipods. We’ll save the world by deforestation!

  27. Mike Ratliff Says:

    http://abcnews.go.com/Technology/Science/story?id=6339986&page=1

    This myth has been busted. Think about it, how could this actually work? There are no electrodes as with a battery. Maybe they should have tried a watermelon, it is bigger right? That means more power right? (Sarcasm)

  28. website design Says:

    “So I tied an onion to my belt. Which was the style at the time.”

  29. lucas Says:

    No this is not true because You can’t charge an ipod with an onion for two reasons: no anode and cathode to form a voltage pair, but more importantly ipods talk to the charging. But you will get a electric charge from it because an onion is very acidic so that brings me to say total hoax and me a 13 year old can figure this out its prity sad that over half the people on the internet tryed it or believe it .
