  • The batteries in the modern electronic devices are unable to cope up with the power demands and often die out in few hours. Unfortunately, power points may not be available 100% of the times when you are running out of battery and want to perform that important task or make a call to your boss. The hand powered mobile charger will solve that problem for ever.

    The project would involve developing a mechanism of the size of a regular phone that would let the user press a clutch repeatedly and then convert this mechanical energy into electric energy. A kickstarter project, called Mipwr has developed this as seen in the video -



    I'm sure this can very well be a third or final year engineering project.

    That is right. I remember that in the early post war days, there used to be a hand operated torch light. You held it in the palm with the lever under the base of the thumb and repeatedly squeezed the lever. It used to make a whirring noise as the speed increase gears worked and the tungsten bulb used to glow. Depending on the input the light would be dim to bright. If the squeezing was slow the bulb would wax and wane.
    If I remember right it was an AC generator.

    30 seconds of talk-time with about a minute of hand-exercise to charge the mobile. Not a bad deal, I must say.

    yes its a great idea and solves the problem of low power source in smart phones.
