Kinetic Leaf

Leaf Wireless Mouse scores big time on looks and has a decent enough direction as far as tech aspects go. The one thing that we do with our mouse the most is to move it around. Based on this, the designers have created a concept that uses its motion to self-power the mouse. It sounds like a whiff of air for now, but imagine if we could have a wireless mouse that did not tank up on so many batteries every month? Because I use it so much, I tend to replace my Magic Mouse battery every 7-8 days. I say go for Leaf right now!

Designers: Lu Hairong and Zhang Xuehui

    This “Self-powered SYSTEM” reminds me of the Iron Man 2 Power Core…
    Nice renders and graphics though.

  • Roya Gharavi says:

    This is rather awesome. May need to invest!

    Nice idea, but it seems to be a step back to the past. one of the drawbacks of having a non-optical mouse is that the ball guiding always gets jammed up with dirt and dust. if there is one thing that is annoying, it’s a mouse that doesn’t want to slide.

    you could also put a coil in a conventional optical mouse and a permanent magnet in the mouse pad. while you moved it around you would also generate electricity.

    Yes, but Mr. Stark’s heart was self-generating even when he wasn’t moving.

  • Hunter says:

    Electric generators depend on circular motion in a decidedly (counter-)clockwise direction to rotate a turbine. A generator contained in a mouse (or mouse pad) would require the user to maintain such motion to be effective.

    If the mouse moves circularly in the other direction, the generator will needlessly consume energy at the same rate at which it generates energy otherwise. This would create an exorbitant amount of heat (unused exothermic energy), burning the user’s hand or, in a rare case when the user is neurologically insensitive to heat, starting an electrical fire.

    Moving the mouse in a straight line could drive the generator’s turbine either direction. Similar complications might ensue, but are less likely.

    Needless to say, this product will require significant technological advancements in the area of kinetic energy conversion, as well as a a copious amount of volunteer-operated testing.
