Urine Powered Battery Developed

ScuttleMonkey posted more than 9 years ago | from the powered-by-relief dept.

Science 286

Saeed al-Sahaf writes "Research investment into developing smaller and cheaper chips to process information in disposable health tests has been significant, but they were still reliant on an external power source. The researchers at Singapore's Institute of Bioengineering and Nanotechnology think they have overcome this problem with their latest urine powered battery. From the article "The battery is composed of paper, soaked in copper chloride, sandwiched between layers of magnesium and copper. The whole thing, once laminated in plastic, is just a millimeter thick, and 6cm by 3cm in size." The breakthrough promises a cheap and disposable power source for home health tests."

January 31st, 2005, was the last day that Michael Sims, Nazi editor [slashdot.org] of Slashdot, ever posted a story or indeed was ever heard from again. But what happened that day to Michael Sims? Did his embroilment in the Censorware.org conspiracy finally catch up with him? Or was he involved in a violent, and ultimately fatal, lovers' spat with his partner Jamie McCarthy? The truth, as we'll see, is much more perverse than fiction.

On New Year's Eve of 2004, the entire Slashdot staff was throwing a party to celebrate another year of Linux propaganda, homosexual recruitment, and the profits that their Microsoft ad banners had raked in for them. Eric Raymond, Emad, Roblimo, Hemos, Taco, Jamie, and Alan Cox all planned to rape Richard Stallman later in the night. Michael had shown up late, however, and was let in on the plans after they were made.

As it turned out, Jamie was to be leading the charge against the Free Software Foundation's founder and would be the first to penetrate Stallman's hairy unwashed ass. Michael, however, was jealous of this and made secret plans to thwart their nefarious venture of homosexual rape. The event was planned for zero hours, right as the ball dropped but Michael had other ideas.

Michael suggested they all toast their plan with Jägermeister, Eric Raymond's drink of choice that was in heavy supply that night, and the rest of the partygoers followed. While everyone downed their first shot, Michael slipped into the VA Software office's break-room, grabbing the syringe Raymond used to inject Rob Malda's semen with on the way. Michael leered at the case of Jägermeister, needle in hand.

Minutes later, Michael reappeared in the conference room with more Jäger, ready for more shots. Over the next couple of hours they indulged in several drinking and party games, spurred on by Michael, as they drank bottle after bottle of the dark brown herbal liquor. If one were to pay special attention to Michael, however, they would note that Michael drank much less than anyone else and only from his own bottle.

Emad and Roblimo were involved in a powerful sixty-nine cheered on by Hemos and Alan whose bent geek penises throbbed near Emad's head and Roblimo's bloated ass, waiting for an opportunity. Moaning, Emad diverted his wet mouth from Roblimo's butthole and took down Hemos and Alan's cocks in quick succession. Hearing the wet, sloppy commotion behind him, Roblimo lost control and glunked all over Emad's chest.

Across the room near the podium, Eric Raymond was man-handling Rob, jamming a handgun down the back of his pants and asking him if he remembered their special night in Holland [slashdot.org] . Rob was giggling like a school girl and squirmed with all his might against the cold steel. Eric rained a shower of Jäger over Rob's head which Rob greedily tongued up even as Eric's skinny red penis entered his ass cheeks, probing for the brown prize.

The conference room was awash in gay cum and chaos, Michael noted happily as he surveyed the carnage around him. Emad had now teamed up with Alan and Hemos to rape Roblimo's ass as Rob was being pistol-whipped to orgasm by Eric, all oblivious to the massive amounts of Rohypnol they were ingesting as they drank the Jägermeister Michael had given them. It wouldn't be much longer before the drug took effect.

Another half-hour into the night, Eric paused from raping Taco's mouth and sodomizing his anus with his Glock, short of breath. His head swam and he looked at his bottle of Jägermeister. I can usually down six of these babies, thought Eric, wondering why he was now farting uncontrollably. Rob's nose wrinkled as Eric's rectum expelled another gallon of aerosolized feces into the air. Stooping, Eric held on to the podium for support.

Across the way, Emad pulled his tiny Iranian dick out from between Alan and Hemos's in Roblimo's ass and doubled over. Alan and Hemos continued pounding Roblimo's purple, swollen anus even as Emad bgan vomiting all over their cocks, thinking it a move on Emad's part to spice things up. Roblimo passed out again for the fourth time that night, but as Hemos slapped him, he failed to wake up.

With Emad vomiting even more violently now, Hemos wondered what was going on. He held a hand to his head as he began forgetting why he was balls-deep in some old man's ass. Alan began hiccuping, which led to uneven strokes and finally a quick orgasm which was quickly washed away by more of Emad's vomit. Nausea rose in Alan's throat as the scents of semen, man-ass, sweat, and vomit overcame him.

Michael was smiling from the corner chair at the table when the telecom beeped. He quickly left the conference room and headed toward the VA Software compound's front doors to let RMS in. As he rounded the last corner, however, Michael almost dropped his bottle of untainted Jäger when he saw that Stallman was not alone. Standing next to him was the CEO of VA Software, Larry Augustin.

His mind racing a thousand miles a minute, Michael feigned a security malfunction when he tried to open the door, leaving Stallman and Augustin stranded outside in the cold. Waving his hands in, Larry Augustin was about to get a slim-jim when he stopped, staring, right behind Michael. There, crawling on the ground, was Rob Malda in his familiar green-and-white plaid shirt, covered in chunks of semen, blood, and feces.

Rob Malda looked up at Augustin and feebly reached out to him before vomiting on the cold tile floor and passing out with a squish in his own sick. Larry and Richard's faces were masks of horror and disgust, and they wasted no time in forcing open the doors. Larry disabled the alarms while Richard checked Rob's pulse. As Richard loosened Rob's collar, Larry turned to Michael.

What the Hell happened here tonight?

The conference room was a mess. Feces covered the wall and in some places even the ceiling. The carpet was soaked with blood, semen, diarrhea, and vomit in a stew so unimaginable that the room was later bulldozed instead of being professionally cleaned. On the dry erase board, someone had gotten creative and drawn erect, ejaculating penises in their own poo. And behind the podium lay Eric Raymond, sleeping fitfully.

At the other end of the room, Emad was curled into fetal position surrounded by a lake of vomit and curdling shit, both trailing from his soiled form nothing new to him [slashdot.org] . Hemos and Alan laid moaning next to one another, limp dicks in one another's slimy hands. Behind them the Roblimo's morose form breathed shallowly, ass in the air where he has passed out earlier. He farted in his sleep as Larry Augustin looked on, mouth agape.

Next week, Larry Augustin held a special meeting with the Slashdot staff. Emad, Jamie, Roblimo, Rob, and Hemos all seated themselves and the meeting began. Eric Raymond also showed, though everyone there seemed a little perplexed. Their party had gotten messy but no one remembered how. Eric wanted especially hard to remember, he thought as he patted his stomach, which still gurgled painfully.

Early in the wee hours of January 1st, 2005, Larry watched as sickened paramedics loaded VA employee after VA employee into the backs of ambulances and raced them to the hospital. They were treated for dehydration and were all given stomach pumps, enemas, and several rounds of antibiotics. They were also tested for drugs and the results were more than a little surprising. Michael, however, had been the only one to test negative.

Hour after hour went by in the VA board-room as each one of the partygoer related their experience. Roblimo took the mic, now wheelchair-bound, and shared his experience that mirrored everyone else's: After his first few toasts of Jägermeister, he remembered nothing save waking up a day later in the hospital, tubes and wires trailing from his bruised body. Roblimo was also suffering from a prolapsed rectum he had no memory of.

It was decided by a unanimous vote that Michael Sims was to be fired with due haste, as he had drugged the entire Slashdot staff in an attempt to rape them all. Unfortunately, due haste took about three-and-a-half weeks so the shareholders could approve the move. Their reaction to the story removed any doubt about Michael's fate and the motion was carried unanimously. Michael was terminated January 31st, 2005.

So now you know why Michael Sims hasn't posted any new stories to Slashdot since January. Let it be a warning to you, reader, of what evil lurks in the hearts of psychotic Linux zealots and Nazi propagandists. Since then the boys at Slashdot have been able to laugh it off, but consider their depraved anus-games. You might not be so lucky were Michael Sims to happen to you. You have been warned.

Thank you.

Why don't we have hand cranks? (3, Insightful)

hellomynameisclinton (796928) | more than 9 years ago | (#13325699)

Why don't they just give us a hand crank? They're more than efficient to power or charge all sorts of small electronics. All we need is a universal plug interface, and we can all be our own emergency backups.

"Pee in this... and turn this."

While they're at it, why doesn't my car have an emergency gear/wheel/crank system that I can connect ot my battery on cold days when my Jolapy won't start?

There is no way you could crank enough to generate the power to start your car. You would be better off with a crank for the engine.

My dad had an old Model T with an actual engine starting crank. Do it wrong and it could backfire and break your arm. I wouldn't call it convenient either, unless you're some sort of armwrestling champion.

Thankfully it also had the electric starter option.

Actually I always thought hand cranks were very convenient. Never had a Model T, mostly tractors or stationary engines. You are correct that they can be dangerous, but that has very little to do with convenience. There are many things that are convenient, but not safe.

Regardless, seems to me it wouldn't be hard to engineer a hand crank that is a little safer than the one on the old Model Ts. Something with a one-way clutch that can't pop back and hurt you. Maybe with a gear reduction so it's easier to turn. Many of the engines in modern cars are smaller than the old Model T engines and probably turn easier, so a crank could be a viable option.

temojen (678985) | more than 9 years ago | (#13325809)

Because it needs enough power to run the fuel pump, injectors, ecu, ignition coil, ignition system, oil pump, and turn the engine fast. Plus batteries & alternators are plenty reliable enough in most conditions, and less likely to break your arm on a backfire.

On Radioshack you can buy a hand crank operated radio.

Build a generator yourself, it's not that hard, it involves magnets and copper wire.

If what you want is standard hand cranks and plugs, and stuff, then it would have to be actually useful. Sorry , it isn't.

The urine is only the electrolyte, the chemical reaction would be: Mg + Cu2+ --> Mg2+ + Cu The battery would also work with pure water. But the whole thing won't be a very "clean" source of energy. Copper chloride is not good for your environment.

So, let's get some facts...Jeeves says [ask.com] that normal humans feel the need to urinate when they hold 150 - 200mL of urine in their bladder. 200mL sounds decent for this math.

200mL / 0.2mL per battery = 1000 batteries that can be charged on a normal fill of urine.

1000 batteries * 1.5 mW per battery = 1.5 W
1000 batteries * 1.5 V per battery = 1500 V
1.5W / 1500V = .001 Amps = 1mA

So, my own piss only has as much power as a spark of static electricity. Sorry folks, but it's going to take more than one run to the toilet to power your laptop.

1 battery outputs 1.5 mW / 1.5V = 1mA

theoretically you could get 1A at 1.5V by wiring them in parallel, OR 1mA at 1500V by wiring them serial, both outputting 1.5W of power.

If this thing could be made small enough, it could be put within the <a href=http://en.wikipedia.org/wiki/Urinary_bladder> bladder</a> (1.1 to 1.3 litres) to work as a permanent machine. It could talk using 802.11b and bluetooth, be its own 'hotspot' so that a human mesh can be made. You wouldnt need to carry a wallet at all. It could also check your health that way. I wonder if it can be used with a plug and an actuator to 'hold it' for you when you really have to go and have nowhere to go.

Are they sure that it's urine powered? (4, Informative)

ChiralSoftware (743411) | more than 9 years ago | (#13325889)

It sounds like it's using urine as an electrolyte. That's like a "potato battery", which again is just using the potato as an electrolyte, and is not getting any power from it.

They should make diapers with this, so when your baby pees itself, you'd know to change their diaper before they have to cry.

Better yet, when the baby pisses itself, it will get an electric shock. Quick, easy toilet training. They need a similar technology for streets in San Francisco.

I'm afraid this post will get lost in all of the pee-pee jokes, but what the hell. I don't see what function urine serves in these batteries. I didn't think urine was all that energetic. The article says these things can output a maximum of 1.5 mW at 1.5 V, so why not just use a tiny alkaline battery? A very tiny battery could be produced for a few cents and they have shelf lives of several years. I just don't see why you need to involve urine at all (other than the fact that it gets your research in the news). What am I missing?
