Cheers To Finger Power!

Cheers To Finger Power!

Mind you, this is not a “Green” concept and neither does it claim to be “Eco Friendly”. It’s just a helpful solution for a tricky situation. The situation being: you running out of juice on your mobile phone. So what do you do? Remove the battery from the back of the phone; give it a few good turns around your index finger and its gathered enough power to last you a conversation or a safe trip to your charger and electric point.

    WOW, almost a whole webpage of people with no imagination, ability to see a very plain picture presented to them AND the inability to have figured out by now that almost all things of this sort improve in time.

    Examples: Is anyone on this page who is knocking this device actually typing their complaints on a Commodore 64? I thought not. You know why? Technology starts off as an idea, moves to an inefficient product then over time gets better. It is extremely possible that in 1-5 years that 130 turns decreases to under 100 and the time gained increases from 2 minutes to 10, or more.
    And does NOONE see the grooves built into the hole where the finger is placed. that is there so it gets a firm grip on your finger so it DOESN’T go flying off.

    Oh and I mentioned earlier about the human charged flashets thsat you shake to charge a very small battery. Smartphones have plenty of room inside if you make the battery just a bit smaller to make room for this type charger. I very much believe that an improvement in magnet types and a few tweaks could and would make this type of charger much more efficient and very practical for devices that are as big as a smartphone and it easily solves the non removable battery problem.. I can envision 2 minutes of gentle shaking for 5-15 minutes of talk time as these charges are improved AND the power consumption of these devices decreases. Just look at the decrease in power needed to run the processors in phones today compared to less than a decade ago.

    You people act(or actually believe? God I hope not) that once something is invented it can never be improved.

    nice concept but you have to switch off your mobile every time the battery is low. This mexhanism must be directly fitted into the mobile so theres no need to restart the mobile….. anyways.. good work.. keeep it up..

  • Awesome!!

    Forget smart phones and just put one of these in my kids toys. They are killing my budget with their need for batteries!

    I used to rewind my cassette tapes this way to save batteries on my Walkman. Nice idea for a battery!

    How many times have you been in a cab or a plane and couldn’t use your cell because your battery was dead? This concept is absolutely necessary!

    Didja know lawnmowers usually have gasoline in them too?
    I don’t usually comment on things I stumble onto, but I feel that this silliness warrants a reply, regardless of whether or not it will be read.

    SpencerC :
    Okay. Good idea. But what about FINGER size? Are there going to be different sized batteries? What about people who don’t have average finger size (i.e. large or small)? Are they left out of the mix now?

    OK, I know this is from way back, but are you really trying to claim discrimination against people with fat fingers?!

    It’s about emergency situations, not to replace traditional charging methods. @Cheech

    I, too’ stumbled here. And I read it. I couldn’t help but to reply to some of the bonehead comments.

    Pretty cool, a little weird to see the comments so spaced out.
    I was wondering though, what about other phones with non-removable batteries?
    Like if per say it was an iPhone or a high end Android phone?
    Also, would it fit every battery size/type?
