Energy From Vibrations
JN writes "Now here's a nifty invention. What started off as a Small Business Innovation Research grant from the Navy to a MIT professor has turned out to become a great mechanism that harnesses running machines' minute vibrations into energy. The possibilities are limitless. Aside from the obvious, imagine the ultimate cellphone - one that charges the battery every time it rings/vibrates, hence promising extended talktimes, and giving operators all the more reasons to get their customers to use their devices. How cool is that? Do I see 3G applications with a vibrate() call mandatory every couple minutes?
"
On a Harley block these could power my Microwave!
I know plenty of women that get energy from vibrating objects.
Insert tasteless joke about Dildos here.
Since the posts thus far are mostly about cell phones regaining power by ringing.. Step 1: Vibrate. Step 2: Violate laws of thermodynamics. Step 3: ? Step 4: Profit!
Job? I don't have time to get a job! Who will sit around and bitch about being broke and unemployed then?
Perpetual Dildo
Yes! A phone that charges itself when it rings or vibrates.
And next, we can build a machine that, when slowing down from drag, uses that potential energy to cause another part of itself to move faster. Then, it would never stop. We could task it to make electricity to power... everything!
From cars that have more electricity at the end of the trip than when they started, to bicycles that coast faster when going uphill, the possibilities are... perpetual!

I sure hope you are just making a joke. If you're not being deliberately stupid, I impressed by your natural talent.
Anything that obtains energy from vibrations or sound is going to dampen those vibrations or muffle the sound [same thing really]. If phones can save energy like this, maybe you can levitate by pulling your own hair up. In fact, I recommend you try this.

I suppose it's all in how you read it... Note the word 'extended' though. In my dictionary, 'extended' does not equate to 'infinite.'
Slashdot laziness takes an all time low - now people aren't even bothering to read the post itself. What next, just read the headline? The first word of the headline? The first letter?
Ack!
maybe you should stop shoving the phone up your ass then?
No only if they could harness the wasted energy that sites writers use by making all the "high-tech" terms in their articles clickable to websearchs of the said terms to try and make it seem "cutting edge" internet reporting.
Yeup. " Do I see 3G applications with a vibrate() call mandatory every couple minutes? "
You're lazy, all right.
Test your net with Netalyzr
now if I could hook up my Utah Cold Fusion Battery
I could sell back power to the power Co. every night when I plug in my c-phone.
Do I see 3G applications with a vibrate() call mandatory every couple minutes?
;-)
And I thought there was just *one* of them G thingys that needed vibration.
And now its gonna be mandatory?! Every 2 mins?
ahem
This is one slashdot story I'll need to read at -1, just for the vibrator trolls
I dunno about this -- my girlfriend seems to have no energy whatsoever left after I apply vibrations to her for 10-15 minutes straight...
Please. Everyone should make basic errors in logical reasoning in their submissions, that way, we'll never talk about anything else. Slashdot will be ruined. My evil plans will come to fruition! Ah ha ha ha ha HA HA HA!
There are no trails. There are no trees out here.
12 inch vibrator! Save the environment while you pleasure yourself!

Those squiggly pens could be perpetual motion generators! :-)
Pam and Tommy Lee could have powered the United States while they were together..
The San Andreas Power Plant..
The London Philharmonic Orchestral Power Plant..
Unrepaired PowerMac G4's could power themselves

I thought the Second Law said something about Robots being forced to obey humans except if it would harm humans :)
It would help keep the device charged. Because to capture the energy, the vibrations would be dampened such that the phone *wouldn't* vibrate and then you wouldn't answer it. And as everyone knows, If you don't use the phone, The battery won't run down as fast. Of course, it would cease to be useful as a phone. But that's usually what you get when you try to get something for nothing.
Hemos is like a lot of sci-fi fans: he thinks technology is cool, but he hasn't bothered to understand the science it's based on.
:)
That's the most concise description of many sci-fi fans I think I've ever seen. I think I'll have to file that one away for future use.

Hate to reply to myself, but....
What about hooking your sister/daughter/wife up with a phone that generates electricity when she's talking. That could really answer the worlds energy needs...
At least pay for the phone calls themselves...
"Hon, time to call your mother again, the lights are getting dim."
"Unless the phone happens to be one of those nifty wrist-based one, the answer is no, this won't work."
:)
1: Momentum powered wrist cell phone
2: Porn
3: !!!!!!!!!
4: Profit! (or at least unlimited power!)
Can't believe that in Slashdot, and in the 21st century, some people still think you can get "free energy"... sigh...
:o)
Hey, you can!
Just run an extension cord over to your neighbor's house when he's sleeping
Slightly OT, there are actually watch stands made specifically for these kinds of watches. You put your watch on it, and there's a motor inside that swings the whole thing from side to side. How do I know this? I saw such a contraption on eBay once. It sold for about $300. It's really one of those "WTF LOL" things.
Did you know you can fertilize your lawn with used motor oil?
They cant do THAT!
I have a patent on perpetual motion engines!!!!!!
I'm gonna sue
lick the cancle button (at least thats what our Chinese QA says)
My girlfriend certianly seems to get a lot of energy whenever anything vibrates near her....can I claim patent infringement?! ;-)

How marvellously novel. I'm sure no-one has ever found a way to absorb energy from movement and store it for later use before, or turn that stored energy into electricity.
And on the subject of using the phone's own vibrating alert to recharge the battery: "Lisa! In this house we obey the laws of thermodynamics!".
You win again, gravity!
Damn thermodynamics... always holding us back.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
Just raise the taxes on crack.
Imagine an energy scavenger like this inside a standard PC keyboard. You could power Intels hungriest processors using Windows and Ctrl-Alt-Del...
In this house, we OBEY the laws of thermodynamics!
Random is the New Order.
Lisa! In this house we obey the Laws of Thermodynamics!

That explains it !!
It's not their body heat - it's the cell phones of all those sleeping people that power The Matrix.
Now I understand.
More importantly, let's hope for commercial windmill farms that don't kill birds.
better yet, a windmill farm that converts the birds it kills into energy.

Do I see 3G applications with a vibrate() call mandatory every couple minutes?
You do not. MC Hawking wrote an excellent article on why this wouldn't work:
Entropy, how can I explain it? I'll take it frame by frame it,
to have you all jumping, shouting saying it.
Let's just say that it's a measure of disorder,
in a system that is closed, like with a border.
It's sorta, like a, well a measurement of randomness,
proposed in 1850 by a German, but wait I digress.
"What the fuck is entropy?", I here the people still exclaiming,
it seems I gotta start the explaining.
You ever drop an egg and on the floor you see it break?
You go and get a mop so you can clean up your mistake.
But did you ever stop to ponder why we know it's true,
if you drop a broken egg you will not get an egg that's new.
That's entropy or E-N-T-R-O to the P to the Y,
the reason why the sun will one day all burn out and die.
Order from disorder is a scientific rarity,
allow me to explain it with a little bit more clarity.
Did I say rarity? I meant impossibility,
at least in a closed system there will always be more entropy.
That's entropy and I hope that you're all down with it,
if you are here's your membership.
Chorus
You down with entropy?
Yeah, you know me! (x3)
Who's down with entropy?
Every last homey!
Defining entropy as disorder's not complete,
'cause disorder as a definition doesn't cover heat.
So my first definition I would now like to withdraw,
and offer one that fits thermodynamics second law.
First we need to understand that entropy is energy,
energy that can't be used to state it more specifically.
In a closed system entropy always goes up,
that's the second law, now you know what's up.
You can't win, you can't break even, you can't leave the game,
'cause entropy will take it all 'though it seems a shame.
The second law, as we now know, is quite clear to state,
that entropy must increase and not dissipate.
Creationists always try to use the second law,
to disprove evolution, but their theory has a flaw.
The second law is quite precise about where it applies,
only in a closed system must the entropy count rise.
The earth's not a closed system' it's powered by the sun,
so fuck the damn creationists, Doomsday get my gun!
That, in a nutshell, is what entropy's about,
you're now down with a discount.
Seriously, if the Sun and the earth were the only two objects (no third body problems, PLEASE!!!) and they were point masses then it should from a newtonian perspective always revolve with the same speed for all time.
If there were no third bodies (as you said), and the sun and earth were in a closed, complete vaccuum with no other matter (which they're not), and the radiant energy from the sun didn't have any effect on the earth's movement (which it does - albeit very, very slight) then yeah, they should always rotate the same speed for all time..
But to paraphrase Suzie Derkins, "as long as you're wishing, you should ask for a pony."
Solution:
1- Buy cheap, efficient, quiet motorcycle
2- take motorcycle to local adult store
3- buy the largest vibrator they have, tell them it's for your girlfriend (it's not like they know you're a geek) make up some story about you having to go away for a week and her needs needing to be filled or some junk.
4- Utilize your mad case-modding skillz to make a recess for the vibrator and connect it to the bike's electrics.
5- Profit
6- ???
