    This is totally off the wall but...

    I had read something about a concept to kinetically charge a mobile phone, sort of like the Seiko watches, and someone had posted that his phone didn't get a lot of "action" to make anything like this feasible, even if the technology involved was efficient and compact enough. However since Android, WebOS and iPhones are all bedecked with accelerometers, would this be somehow more feasible for smartphones?

    The way I see it, smartphones will benefit from more movement, other than just riding on your belt: (1) movement-based apps, (2) smartphones have more uses than just calling, so will be handled more in general, (3) The Pre and G1 both have sliding keyboard motions that might be harnessed as well.

    At this point, I'm only talking about on-board solutions (or even built into a special battery), since I've seen many other compact human-powered solutions (with a crank, by shaking, etc.). Nevertheless, some of these other solutions could be used and rebranded by Palm, e.g. a mini-Touchstone shaped beltclip contraption in which you could charge a second battery...perhaps even integrate such a combo into a belt case, although how dorky would that look?

    There is a company that is running with the idea: M2E Power

    Their utimate goal is a cell phone battery that will recharge itself using kinetic energy. No need to re-engineer the phone.

    I'm not sure the technology is small enough yet to make this feasible. A watch has much less power draw than a cellphone.

    I hope this company comes up with some way around that though... I had the idea a while back that there should be Wii remote batteries that worked like this, it'd be perfect.

    Ours gobble rechargeable batteries like there is no tomorrow.

    I have a kinetic flashlight here... Has NO battery in it at all..

    Here is a 2 stage idea....

    Build a new keyboard... One that the keys actually produce energy when you press them down (Transfers the mechanical energy from you pressing the buttons down into electrical energy..)
    For those of us who use our phones heavily for email, texting and such we could be recharging our batteries all this time...

    As for over all inductive and or kinetic recharging... Who here wouldn't put up with a large battery back if we knew our 650mh battery was being recharged constantly and the only time it WASN'T being charged was when it was still. And heck if it is still just put it in stand by mode. If you have an active charging system in place why do you need a big battery?

    With the technology and miniature circuit components and such there is no reason not to believe we could have a battery design that could allow inductive charging IN the battery... Now that there is a charger available there is no reason to believe third parties can't take this idea and run with it (Of course depending on patents and such..) You might require a larger battery physically (Like the 2400mh batteries) that actually have smaller capacity but have the charger built in. You could figure once someone has this gimmick figured out it could "explode" on the market.. Just make the inductive charger the same across the board and you have a true universal charger. Now that you will have a phone available with the technology there is no reason not to believe you will see advances both ways...

    By both ways I mean you could start seeing self charging batteries, and some different designs of inductive chargers.

    Now we don't need no stinking ports on the phones to go bad... Blue tooth for your listening pleasure, wifi/bt/3G/4G to connect to your PC, and inductive charging for your charging...

    As to kinetic charging.. I am betting you will more likely see this used to extend battery life as opposed to actually charging your battery. Now unless you wear it while you are at basket ball practice or something like that then you may not get enough movement to actually charge the device. However slowing down the discharge of the device so you get 24 hours or more use out of the phone etc would be a much more efficient use of the "charger". Now backing this up with an inductive charger as I have already said would be the cats meow...

    The technology is NOT cheap and the first few batteries could end up costing $100-$200 when designed as a low volume add on but as it gets used and the shear volume of them being in place goes up you could see it being the normal way to do things in a phone...

    It would be well worth the effort and engineering since there are some kinetic energy producers now that are pretty tiny. Build them into the phone and you could end up making the battery in the phone more of an accessory then a necessity. This also works with any other device you might carry on you to use. (Mp3 players etc..) In that case the battery would be more for use in keeping the phone in standby when you are not moving and if the phone is designed properly you could end up with a soldered in battery that never needs to be swapped out.

    Another technology I am surprised we have not seen much effort placed in is using body heat to produce energy... No reason to believe you couldn't take body heat and produce a charger of some sort as well.. But any such charger would likely be more of a battery drain slow down then a full device charger.

    Ok enough brainstorming and fantasizing for one day...

    But you can begin to see the way things could go with these suckers...
    Anything to keep me from burning up batteries in my phone every 4-6 hours... lol

    I read an article somewhere that scientists are trying to convert radio signals (such as wifi signals) into something that charges your phone. How cool would that be? As long as you are near a wifi signal somewhere, your phone is getting charged.

    I'd bet that you'd need a large physical area to capture the most waves. Foil Wifi collectors-hats anyone?:



    Any wireless specialists out there? Could you use existing metal structures (e.g. your desk, bus stop shelter, Golden Gate Bridge) to somehow get wifi to move electrons? I'm sure shape matters as much as composition...nano-shapes maybe? Imagine if you could actually get some sort of nano-based fibre to collect ambient microwaves, and send it to your microUSB host cufflinks. Not only would you get free electricity, but you'd be shielding yourself from dangerous brain-cooking, hard-boiled-egg-making microwaves!

    Recycling wireless signals into usable electricy sounds fascinating!

    (As I'm typing this, this tic in my leg is making it tap up and down...I'm sure I could charge 10 Pre batteries a day if you stuck them in my heel!!! Then at least my wife wouldn't say "cut that out", she'd say "are you done charging my phone yet?")
