    "Motorola claims that 45 seconds' winding will produce 4-6 minutes of talk time and 'several hours' of standby time."

    That's actually not bad at all. The only problem is that if you wind it to get standby back, if someone calls you are likely to only have a minute or so of talking. This seems like an excellent idea for emergencies though.
    • The only problem is that if you wind it to get standby back, if someone calls you are likely to only have a minute or so of talking.

      Simple. Turn off the phone while charging it. Turn it back on when you're done.
      • Turning off the phone while charging it may or may not help. Imagine this scenario:

        You are waiting for an important call at the beach (don't ask =] ). Your cell phone dies. You wind it up to keep the phone on standby so you can still get the call. Depending on when the call actually occurs, you may only have a couple minutes of talk time. Of course that would be enough to let the caller know the deal, and then call from a pay phone, but hey *shrugs* :)
    • The only problem is that if you wind it to get standby back, if someone calls you are likely to only have a minute or so of talking.

      Who told you to stop winding after 45 seconds? D-oh!
    • Unless you are in a real emergency. 45 seconds could mean the difference between life and death. Something quicker, like a pump or maybe the use of gears to make the charging quicker would be great.

      It is understood the more work you want out of a system, the more work you have to put in. (Energy can't be created etc...)

    • The only problem is that if you wind it to get standby back, if someone calls you are likely to only have a minute or so of talking.

      Could be a potential problem when I call up those automated voice mail hell^Hp trees that force me to navigate <wind>through the <wind>duration of every inappropriate <wind>branch and <wind>twig until I get to a nice operator <wind>leaf that puts me into a queue to talk to a real person.

      "Thank you for calling $CORP. <wind>Your call is important to us. All of our operators are busy assisting other customers. Please <wind> continue to stay on the line...<music> ... <wind> <product_advertisement> ....<wind> ..."

      (I can see carpal tunnel setting in from winding...)

    • So wind while you're talking.
  • This is nothing more than a dynamo flashlight or disaster radio without the bulb or radio.

    I'm not impressed!

    For years, I've been excercizing for this product, once, twice, or sometimes even three times a day. At last all that hard work and repetitive motion will pay off.

    And if I can get one of those phones that can view color photos, I might be able to continue excercizing after I've charged it.

    Unfortunately, it's not integrated into the phone. There are uses for an "emergency phone" with a built-in crank generator. But this is an external unit you carry around.

    A "squeeze the handle a few times and you can make a call" unit might be more useful.

      Watches are at a pretty high torque point, on your wrist, and will get a lot more energy than something clipped to your belt.

      Also watches require much less power to operate.

      Because watches need fractions of a milliwatt to operate, while a phone typically needs a watt. That's over 1000 times more, in case you're SI-challenged.
    • Because a watch is not only on your hand where it is flailing around all the time, but they require _very_ little power.
  • OK you better be away from a power source for a LONG time before you need one of these. Granted if you were realy desperate and bothered to cary this small brick around with you. The battery side that takes 36 minutes of winding to charge is 1000ma assuming you would spend an hour a day winding this thing up (or just plug it into a socket and recharge it) and that it weighs in at two thirds of a pound you would be better off getting a few extra cell phone batteries (yes some people do actualy remove there battery and replace it every now and again)
    • The point isn't to charge it to capacity, the point is to get your phone running long enough to place a call if your battery goes low.

      I don't get many calls on my cell phone, so I get lazy about charging it. If I could wind it up a few times and get 10-15 minutes of talk time (which sounds reasonable based on the article), then it saves my booty if I get stranded or something.

      You're operating on impractical assumptions there. Heh.
  • Uh, not to repeat myself but... Almost usless news connected to products yet again
  • Now your wrist can get tired on all of your phone calls, not just the ones you hope your significant other doesn't see on the bill.

  • As well as the mobile charger modules, you're given a torch module for the FreeCharge. Unfortunately it's a bit disappointing, considering that FreePlay has produced wind-up torches before.

    This sounds like some cool James Bond device. Battery charger for emergency phone calls AND bad guy incinerator!

    (Yes, it's a joke.)

  • There is more info on the product page [freeplay.net] at Freecharge. But I think it would be cool if there were a little more information. The "45 seconds of winding" for what sounds like full charge seems pretty cool. This would be excellent for camping trips and such.

    The nerd in me wants to know if you are winding a sping or direct charging....

    • If you read the article, it tells you that for a full charge, you need 35 minutes of charging. 45 seconds will get you the minumum "useful" amount of charge (enough for a short call). However, the best use of this seems to be to start with it fully charged (you can plug it in to charge it up), and then whenever you make a call, or if it's been idle for a day or two, you wind it to top off the battery. That way, when you need to make your 30 minute call, you can do it immediately and pay for it later, rather than having to wind it for 20 minutes before being able to perform that emergency heart surgery...

    The amount of rigorous cranking it takes to get a charge makes this generator seem inefficient. Maybe efficiency was sacrificed for portability.

    Human legs are much more powerful than arms. some sort of foot-operated device would be more tolerable in terms of effort, but probably not as portable. Piezoelectrics that sit in the soles of shoes are not very intrusive, and could provide power over a long time. I believe this is what the MIT wearables group is using.

    Hand power, foot power, wind power, and water power require different gearing ratios in order to operate efficiently. An impressive design would allow this type of switch through some type of transmission (CVT? Pneumatic?), and have linkage adapters to hands, feet, windmill blades, waterwheels, etc. The problem is accomplishing this while maintaining a light weight.
    • Well then you'd need some sort of cord attaching your shoe to the phone. Or, they could embed the phone in the sole of your shoe. Or -- here we go -- your phone could snap onto the sole of your shoe.
  • What about strapping the thing you your belt and harness the kinetic energy from your movements. There are some things like watches that do this. Of course cell phones use more power than that but, if I get off my fat ass and run the 4 miles home from work, I might build up enough to be able to call and order a pizza. :-)
  • I'll bet they would have liked to have one of these on "Survivor," "Six Days, Seven Nights," or "Gilligan's Island."

    Now if they just would come up with a portable cell tower...

    Seriously, on the chance that in an emergency I would be near enough to civiliazation to use a cell phone, I'd put one of these in the survival kit in my plane. I have a long-shelf-life disposable battery for my Nokia in there now.

    According to the article, there is no clockwork involved in the charger. The handle turns the generator directly. The box is already larger than a cellphone, so why not include clockwork? Instead of using hand power to turn a generator, why not use handpower to compress a spring (at a significant mechanical advantage, of course) that turns a flywheel that turns the generator.

    Of course it would be much harder to turn the crank, but you wouldn't have to keep up an exhausting pace of over 100rpm. At least in my mind, I'd rather turn a very hard-to-turn crank 10 times than an easy to turn crank 1000 times.

    Does this model work? I've seen it work in some of the various other 'squeeze and go' utilities out there. I had a flashlight/FM radio combo a little while back that used something similar (handle, spring, and flywheel arrangement). It was relatively hard to crank, but one or two cranks got you 30 seconds of flashlight or 5 minutes of radio at top volume.

    • Sounds great. But you forget if there's no electricity, then there won't be any antennes from the phonecompany because those need electricity too. And they have only a small radius.
      • A good point, but the nice thing about many lightly populated areas of the world (I'm thinking much of africa, central australia) is that they're (a) flat and (b) have very few buildings. This increases the tower's range hugely. As an example, there is a cell tower on top of the cliffs near Dover (south east UK). If you get the ferry over the channel to france, you can still pick up a signal from it almost all the way over (about 25 miles), because there are no hills or buildings.

But first of all a cow had to be created. And fed. In a place with electric fences. And a sewer system. And grass that had to be mowed by a tractor that had to be created somewhere in Pennsylvania. And then the cow had to be hollered over to the slaughterhouse in a big truck made in Detroit. And the truck would do about a mile to the gallon. And require new tires every 6 months. And the slaughterhouse would have to buy new Magnum 45s every year to shoot the lead bullets in the cow's brain. And all those people that where so busy making your hamburger now also lost energy and could use a hamburger themselves.

    And you call THIS good for the environment?!

    I bought one of those Sony emergency radios, it's bright orange,AM/FM, has little light for the dial, water resistant,an audio beacon (sounds like a smoke detector), and it's crank/battery/ac adapter powered. It's pretty basic, but it sounds okay.

    I bought it to be my work radio, just to listen to talk radio while I'm working in my office. But I started using it in the kitchen while I'm cooking because it's small and durable.

    Anyway, I figured I'd never have to buy batteries for it. If you crank the thing for one minute, you get about 30 minutes of power. But the thing is, it's a pretty stiff crank (heh), and you have to crank it pretty fast. After about 3 minutes, you're pretty much sick of doing it. But that does give you a good hour or so of listening. It'd be good if you were stranded in the woods and you wanted to hear the ball game, or use the smoke detector noise scare away predators. Otherwise, it's just easier to use batteries, which seem to last forever.

    These crank-up electronic devices are really only useful in emergency situations, or by really committed environmentalists.

  • 60 or 70 years after we quit using hand-cranked generators in phones, we get them back again.
  • First they were telling us that moving from hand-cranked coffee grinders to electric coffee grinders was progress. Now they're telling us that moving from electric cell phone chargers to hand-cranked cell phones chargers is progress.

    So are hand-cranks "old-fashioned" or are they "innovative"? Technology is so confusing these days.
