This looks like it has a lot of promise... not so much for regular use so much as emergencies. Laptops have some pretty high power drain sometimes... I'd imagine that a device that can power one for 4 times it owns usage time must require a good deal of input power, aka, work (or the dreaded e (exercise) word).

Also....looking at some of the people this would be marketed to, that five minutes of vigorous activity...man that could be a killer.

Darn, there's so much "brisk pumping" that occurs naturally in society-- wouldn't it be more efficient if we could somehow capture the energy from that?
Wonderful! Now, when my grandmother is knitting me a sweater with her foot-pedeled sewing machine, she can power my laptop too!
This is the answer for XP's peers development utilization question. As one developer would be coding, the second would be pumping up the battery -- no more questionable waist of developers' valuable time by just watching over the coder.

I think it would be great if this device were designed to accept your normal outlet plugs so you plug whatever you want into it without having to buy some kind of adapter... but i guess that means the company loses money on selling you adapters for your gear.. ie: adapter for your ipaq, adapter for your phone.

5 minutes out of every 25 must be spent charging. Ok that means you end up wasting 12 minutes out of every hour. I'd say this is much less than I end up wasting on other things like solitaire, minesweeper. PLUS, you get exercise out of it! Sign me up!
"The StepCharger weighs 10.5 ounces and is roughly the size of a paperback book; it can be used to charge anything from satellite phones to digital cameras and video cameras, as well as laptops. "
I was just thinking such a device could possible adapted to fit on the bottom of your shoes. That way the activity of walking or running could be used to generate power instead of pumping standing still. Man, I must have hit a nerve with someone who's chips and dip ran out or something.
Seems like a rather low yield to me - my grandfather used to sell Singer sewing machines, and has an amazing collection of antiques.
Among them are two treadle style, with a large two-foot pedal, and a long band to transfer the power. That sucker got going REALLY fast, with a lot of momentum. Admittedly, it was all iron as well.
It just seems to me that five minutes of pumping that sucker would have given me about 2 hours worth of laptop power!
You come into work and they've cut every last possible person they can. But they still need cut backs. Next cut, the electric company. The company figures it can save money while keeping it's employees in shape. So 2 of these at every desk. Your required to pump 2 hours a day at first so you can work. It will be raised to 4 or 5 though because the executives will decide they don't want to do it and make you do thier pumping for them. We'll all still be skinny or overweight geeks but well have thighs and calves of steel.

There are a lot of things your clothes do to absorb energy that you don't notice. You don't want the soles of your shoes to be too springy, for example. If you can put some of the absorbed energy to good use instead of turning it into heat, you'd never notice the difference.

I'd have a hard time justifying $150 to recharge a battery with manual labor, when a spare battery can be bought for most devices for a lot less. (especially a cell phone, etc)
Besides, if i'm away from a power outlet of some sort for THAT long of a time, a nice break from the electronics is appreciated.
Sorry, theres only one thing I pump briskly for 5 minutes and I certainly don't get a 20 minute charge out of it.
And if the wall has no power right now, or there is no wall? You're going to feel really silly there with a dying battery and your line-powered charger.

You aren't funny regardless of what three misguided idiots think.
How about shoes which generate power from your step? That way you can be charging while you are getting someplace.
If you are foot-pumping, you have to pay attention in order to keep pumping, and it can really get tedious. Walking is second nature, so you can ignore the fact that you are charging your laptop and it seems like less of a chore.

Another article about generating electrical power from piezoelectric implants in your shoes was posted back in June. Can't say which I'd prefer: constant "trickle" charging from walking around, or Richard Simmons-style express charging ;)
Read my keyboard review.
Sigh. Those gay raver boys have it all.
So by extension, if this device gives the equivalent of wall-socket power, you should be able to recharge the battery while you work (like plugging in your laptop and working), thus obviating the "this wastes 1/5 of your time" argument posted several times above. After all, if N minutes of pedaling gives you 4N minutes of charge, then the battery is charging faster than it's draining, right?
Freedom: "I won't!"
Another approach is to store the power in a wind-up spring, which turns a generator that supplies your power. There's been interest in this approach for years, but it never seems to go anywhere. Probably most people would rather look for a power outlet than turn a crank.

I think the military one is made for walking, the civilian one seems made for stationary pumping stationary pumping. And honestly this doesn't seem to be a huge "Revolution" as this just uses a small generator like design (like those hand pumped flashlights). Now if they made those piezo-electric generator shoes or insoles, that would be cool.

It wouldn't have to be a platform in the platform shoe style. Nike made a shoe that had an extention on the toe only a while ago that was for running in place. Something along those lines would be what I was thinking. BUT, apparently talking about shoes with a pump that recharge electronics is completely offtopic to an article about a device you pump, with your foot, to charge electronics (as the article states, not the /. posting).
It's more usually a sign of stress. It's only (paranoid) schizophrenia when you're tapping your foot because the FBI just passed a message into your brain that if you don't tap your foot they will take you out with their orbital "laser".

:), or buy 2 of them when they'll reach 3rd generation with 15W output.. you'll look like your pedalling at your desk... heh...
Output Power: 0 to 6 Watts / 18 Volts Direct Current (DC18V)
Funny, my laptop draws about 30W of power... I don't know if he talks about powering a PDA or a laptop, but in the case of most modern laptops with almost gigahertz processors with 3d graphics chips and dvd players and 40GB hdd, all of which are power-optimized of course, but still eating a few watts here left and right, it adds up pretty quickly.
Just look at the power rating of your battery, 5000mA/hr 12Volts for example, the battery lasts about 2 hours, if you do quick maths, 5A/hr @ 12 Volts gives you 60Watts/hr, which obvioulsy means you can plug 60Watts power for about 1hr then the battery dies, so effectively, 30W for 2 hours is about right. Now if that device can output 0 to 6 watts, let's take the best case scenario... 6 watts... you'd have to pump 10 hours to keep 2 hours on your laptop.
Unless you're running on a 486 with 10.4 DSTN LCD, I don't see how this is really practical for modern computers... unless you plug the whole office on this to power the server and keep the employees in shape

My brother has for a long time been saying that wherever you have a captive, seated audience you could be generating lots of power.
Think about all those long car trips you took with your family when you were younger. Just imagine how much power you could have produced.
Think movie theatres, assuming it could be made quiet enough.
Think lecture halls.
Think if it could just be springy material which generated a current (there was something about a shoe with that in the sole a while ago I think), then you could put in commonly walked on sections of pavement, or in houses.
While individually, or at once you wouldn't generate any great amount of power, over time with a good battery, and enough people it would start to add up.

I wonder if the Amish could then legally use these then? I know some of the local Amish (mid-east Ohio) are allowed to use compressor powered tools and can even have one business related outlet.

I guess you haven't tried Tantric pumping. It charges you up for hours at a time.
This is somewhat offtopic, but it relates in the aspect of power creation.
:)
Why haven't we created some sort of system along our many many miles of interstates where the vehicles pass over a power generator of sorts? For example, back in the day when you arrived at a filling station, a hose on the ground rang a bell using compressed air. Unless I am totally misunderstanding this system, work is performed by the weight of the vehicle. Why not put these on the roads and have mini substations to collect the energy? I don't mean rubber hoses of course, simply a system that collects energy from weight, like a hydraulic reservoir that gets compressed and pushes on a miniature generator. I don't think we'd want them ringing bells but we certainly could harness this "free" power. There would be costs involved in upkeep and construction, but one would think that the benefits would outweigh these costs.
Another possibility is to put simlar devices in sidewalks that create some sort of power that can be used for things like street lights.
It just seems that in our quest for power sources, we are missing the obvious ones. Let us use what is already working.
It seems reasonable to me, so I'll be waiting for the reasons why these things can't happen.

The latest issue of Fine Woodworking has a short article about an Amish woodworking shop that is powered by a diesel engine driving a big pump to run a bunch of hydraulic motors. All of the machines in the shop had been retrofitted with hydraulic motors. It seems the Amish gent who owns the shop, doesn't use electricity, but has no problem with using heavy machinery. Cost runs about $40/day and the diesel heats the shop as well.

Anybody noticed that there seems to be a problem with the claims presented here?
It seems odd that the charging rate of a personal electromechanical device could exceed that of the power grid, no?
Especially when you notice that the foot pump only produces 6 watts (max) while last time I checked my laptop easily drains above 15 watts of energy.
The article claims 6 Watts of power output.
My previous laptop used about 20W, my current one has a spec stating over 60W on the bottom.
So for a reasonable laptop (25W), it would be more like 20 minutes of pumping would give you 5 minutes of battery life...
