Pullight Dynamo

The Pullight Dynamo looks to be nothing more than a flashlight powered by stored kinetic energy built up from pulling a string. Inside the dynamo is a 3 phase motor to deliver more power from very little kinetic energy. What’s more, the dynamo can charge other devices like a mobile phone or iPod. It’s splash proof and perfect for emergency situations.

    Love the design and neat presentation, Great Product! Where can I buy it?

  • igreenspot says:

    Well, Sebastien should give more than just that picture, I still don’t see how this works. And for jc and nilsson, i’m pretty sure this is just a concept, you won’t be able to buy it anywhere

    Nice Renderings…… Ideas wise, i dont see anything unique or new here since emergency charging concept of using kinetic energy has been long tough before.

    And i agree with igreenspot, the illustration does not show how the product connect woith other device for charging.

    Hmm… doeas any have any clue how many time should i pull the string to charge my iPod ?
    Hahaha….

    overly designed with out a intutive UI…heck the lights are out and you need to sus out how to work your generator….hardly a smart move.

    • A.C. says:

      Dude, you pull the string… seriously, just how simple do you want it to be? God damn…

      • zippyflounder says:

        in the dark, find handle, release handle….sorry just bad design for the application.

          Zippyfounder: MY GOD… your comment is as clever as saying:” go find the switch of a light in the dark ” I dont know Why pulling a string in a dark is a problem?? the device have a built in battery, so in the dark you just suppose to switch it on, BUT if you need to charge it, and you are in the dark, then you just need to take the ring with your fingers and then pull it… IT IS SO SIMPLE!!! your comment is kinda: “What if you are in the dark and ur flashlight that doesn’t have anymore battery?…”

            chill. i agree that the pull string is relatively intuitive and that this is a cool flashlight with some potential, but seriously, if your going to make a critique comment you may want to use proper spelling and grammar…

  • righty says:

    it might be similar to the spin tops where you pull the stirring and spins the base (like a gyroscope) and that could be what is running the KE and everything. Hoped that helped you picture it.

  • sadly this is not even a prototype, but i guess it would work quite well, thinking of the gyro-twister-ball-thingies with the led-lights.

    i would buy one, when they get on amazon.

    I wonder if it scales? A larger model could be useful in third world countries.
