Cell Phones Could Soon Be Powered By Walking

Katia Moskvitch reports for BBC:

Taking a stroll may soon be enough to re-charge your mobile phone, after US researchers developed a way to generate electricity from human motion.

Placed in a shoe, the device captures the energy of moving micro droplets and converts it into electrical current.

Kinetic charging is already used in some low power devices such as watches and sensors.

The University of Wisconsin team published its study in the journal Nature Communications.

“Humans, generally speaking, are very powerful energy-producing machines,” said Professor Tom Krupenkin from the university’s mechanical engineering department.

“While sprinting, a person can produce as much as a kilowatt of power.”

That, according to the scientists, is more than enough to power a standard mobile phone.

    “That, according to the scientists, is more than enough to power a standard mobile phone.” Wow really, I think I may need clarification on that. 

    My 6 year old cousin knows how much a kilowatt is.

    Lets design this into a glove. So every night before bed I can recharge my Prius.

      If it was designed into a glove, I could recharge Google’s entire bank of server back-up batteries.

    This is actually old tech now. The self powered nano devices could become through mass a form of powering everything without it doing anything other than generate electricity by converting the energy of shaking atoms.

    Maybe this could be used to make a self power glove. Arrigato Ms. Roboto

    The technology in this article has been around for a long time and it’s poorly efficient at best. Paying for electricity has been a scam since the early days of Tesla anyways. With our current knowledge and ability’s we can create endless batteries than never run out. I am so sick of this energy embargo they put on people! Right this very moment I have a self-powered magnetic Wankel motor running the entire lighting system in my home. It never shuts off, just runs and runs until the bearings wear out someday. I put a lot of effort into building it, and it is indeed possible. 

    Trolling the internet everyday looking at articles like these and breakthroughs with this and that. It can drive you nuts when you realize how easy it is to circumvent all these energy problems we have. If “free energy” was realized in the majority, or released, and then put into use to meet the energy needs of mankind….. Well then, we solve A LOT of problems! Right? 

    For me, having that ‘realization’ through the actions of inanimate object, has been an ongoing battle. I KNOW FOR A FACT that this current energy crisis is a farce. I don’t, however, expect others to share the same understanding because they have not had the same experiences. I also don’t know any of the answers to most of the questions I have. I don’t know why the millions of scientist worldwide have ignored this, or why they unwittingly fight against it. I understand corruption, but don’t see how it could be used on such a massive scale. There are just too many unanswered questions… 

    So I end up keeping my motor secret from anyone with a closed mind or a big mouth. It saves me a lot of grief and a ton of money on my electric bill. The anonymity on the internet is the only thing that allows me to speak freely about it. The only downfall to that is proof, everyone wants proof. Unfortunately proof and anonymity are mutually exclusive. So I move on, in hopes that my little shared experience will hide out in the back of your minds. Until one day, when our understandings become one in the same, you will have something to corroborate with your thoughts.        

    Now I’m not asking anyone to believe me, it runs regardless of anyone’s thoughts or opinions. (Lol) I’ve heard it all too; entropy this, laws of physics that.. I don’t care, it keeps my lights on, that’s all I care about. 

    Keep fighting for all types of truth out there!           Oh, and the top comment is hilarious BTW ;-)

      You say you don’t know why other scientists won’t come forward about all the tech that can change the world but at the same time you won’t demonstrate or even stand behind your words with your identity.

      We’ve all heard a lot of claims but when there is always a flaw. Takahashi super magnets sound pretty cool but where are they? Tesla transmitted energy without wires, but where is that now? And I’m not talking about power mats or sonicare toothbrushes. Stan Myers water car on and on and on.

      Fighting for all types of truth includes speaking it.

    This is great news! If this is fully implemented in the future, it is possible for us to live in a healthy and energy-efficient world. People will need to take a walk to charge their phones, and this can be beneficial to their health.
