back to article US hackette ponders jub-powered iPod

It's hats off this sunny Friday to US hackette Adrienne So of Washington Post tentacle Slate, who earlier this week pondered the delicious possibility of the jub-powered iPod. As Adrienne points out, there's an awful lot of mammergy going to waste as sporty girls' chesticles resist the restraining force of sports bras and so, …

    Surely you don't need motion to generate electricity, only force?

    A proper sports bra with piezo integrated into the loadbearing members would fulfill both support and power requirements.

    Not that I've spend much time thinking about this. Cough.

    "studied breast motion since 1985"

    Pfft. I've been doing that assiduously since about 1983! Look at all the affadavits I have! Yes, I know they look like restraining orders, but that's just proof of my dilligence.

    I also make available other services:

    Laundry cleaning (please wait 28 days for return of panties)

    Cancer tests (breast only)

    PI (I will follow acceptable clients wherever they go)

    Others on arrangement.

    Dearest Lester

    Did you not challenge Prof Lawson re. the assertion that "a D-cup in a low-support bra can travel as much as 35 inches up and down during exercise"? If this were so such jubs could potentially become deadly weapons and ought to be banned from our streets along with other jihadi-paedo-terror activities like taking photos and walking the streets with your eyes open in the presence of minors.

    Energy Harvesting


    "Perhaps the most well-known of the

    ACI PFC solutions have been those for

    active sports equipment for Head NV’s

    family of Intelligence™ “smart” tennis

    rackets and skis. In these unique products,

    the PFC acts as a sensor of vibration,

    an energy harvester (converting

    that energy to electrical power for the

    dampening circuit) and an actuator to

    dampen the vibration. The positive

    You could modify the garment to reduce bounce by harvesting energy to run a damper. This would remove some of the fun as well as making the bra around ten times its size with all the mechanical and electrical add-ons. Still a worthwhile project.

    Um, the point of sports bras

    Is to inhibit motion. If jigglage still occurs, then the sports bra isn't doing its job properly, surely?

    One which actually allows jiggle, even if it is dampening the motion by using to drive some sort of generator, isn't going to be as comfortable as one that does not.

    3.5 not 35

    sorry to disappoint lads, but a D-cup will only move 3.5 inches up & down not 35inches.

    Whilst fun to look at, this amount of movement hurts.

    The piezo idea is much more likely to be practical.

    Anyone remember the TV documentary

    .. that was all about breast motion measurement/analysis? I saw it in my teens and have had a keen interest in the topic ever since!

    I remember one of my sisters friends was asked to take part in similar research, she was told she'd be filed topless running on a tredmill.. No headshots and it would be anonymous etc. As a student she thought what the hey, but when she informed them she as a B cup the recruiter looked at her sheets and said, oh, sorry we've already got all the B's we need!

    But the overall question is: how come my CS degree didn't have any practical research like this???

    Bounce factor?

    It's like regenerative braking -- it's not the movement that generates the power, it's stopping it. The more effective your conversion, the less motion you'll get.

    As for cup size vs. travel, it depends on several factors. My wife has had two kids and then lost considerable weight, and is taking martial arts and is in better shape than ever. But when breasts shrink, they sag, and they tend to bounce more. So she's always on the lookout for restrictive bras that are reasonably comfortable. ...And not too expensive.

    This has caused her to make such remarks as "You know the pencil test? Well, I pass the typewriter test."

    (Sarah, no need to worry about my marriage. Trust me. :)

    One interesting thing I noticed on the shockabsorber website was that if you picked either of the middle two activity levels, you get more motion than the "extreme" level. Seemed odd to me.

    (And watching those animations made my wince. Ouch. Large bouncing breasts may look sexy but I bet they hurt like hell.)

    And with that I'll leave you with a bit of Ogden Nash. Forgive me if I get it wrong, I'm quoting from memory:

    Dr. Valentine For Once Dreams of Wealth

    Dr. Valentine soon hopes to announce

    He's collecting fabulous amounts.

    He's invented a new bra

    Called Peps-oo-la-la

    Which gives more bounce

    To the ounce.

  45. andreas koch

    So watt?

    What a waste of time this bra thing is... ;-)

    I'm probably spoiling the fun research, but why would you try a bra generator if automatic watches have been around for about 200 years. Surely the movement of a jogger could power a modified mainspring winding mechanism enough to charge batteries, whereever you attach it.

    There's LED torches that are charged with a motion not unlike the one that might be provoked by deep research into this breast motion thing, so why not IPods?

    Stick them things on schoolkids at break time and the schools lighting during lessons would come for free.

    PDAs, mobiles, handheld games and so on, stick it detachable to outerwear and the wash thing won't be a problem either; possibilities galore!
