Bacteria Powered Batteries
Agent Provocateur writes "SpaceDaily reports on
a battery that is powered by chemical reactions caused by bacteria.
A Pentagon-backed project, University of Massachusetts researchers Swades Chaudhuri, an Indian, and Derek Lovley, an American, say the battery's source is an underground bacterium that gobbles up sugar and converts its energy into electricity.
Their prototype device ran flawlessly without refuelling for up to 25 days and is cheap and stable." The chemistry behind this thing isn't really that complex - keeping the bacteria alive and kicking during that time is prolly the tougher part - you can read more on Al Jazeera, and USA Today. Now, what about replacing this battery?
Is it on the back of a Delorean?
Now I finally have a use for all that old pizza stacked up in the corner of my room......

Similar to this Vehicle?
i wonder what the bastard will smell like.. if it isn't pleasant, might take a while to gain acceptance.
then again, if it smells like garbage, maybe it could attract flies, and maybe the flies could feed it.. ah, that would be funny.

Creationists are a lot like zombies. Slow, but powerful and numerous. And they all want to eat our brains.

I've been running my fridge that way for years now!
One line blog. I hear that they're called Twitters now.
Imagine,
a stack of left over pizza suspended by a magnet waiting above "the Pit". when the power drops, the pizza drops.... voila, instant power back-up...
Need more power???, just add pizza.
Why are other peoples sig's always more witty ???
"It has to be able to use raw materials, rather than giving it refined fuel."
Huh? I for one would happily buy one if it could run my 40W max laptop for 8 hours on an ounce and a half (about 50 grams) of refined sugar. Why does it need further refinement before use?
A colony of e-coli bacteria? Like I don't already have enought of that shit floating round my kitchen.
From the article:
This I want to power my car. And laptop. And house appliances (not just so that I can pour coffee on my computer to recharge the battery)
This solves the hydrogen-storing problem in the hydrogen powered vehicles: no more dangerous concentration of hydrogen, instead you get a small tank containing bubbling "mud". Not quite inflammable in case of a collision.
Add to this that it's hardly polluting (just as much as taking a dump in a bosquet, I'd say), and it even helps reducing the amount of houseold garbage (Powerplants recycling garbage, anyone ?).
The main aspect of this energy source is that it completely suppress the need for combustion. Instead it uses slow, catalyzed, controlled chemical processes that use a lower amount of initial energy. No more smoke.
Maybe I'm overstating all this, but it definitely looks cool. And it's cheap, too. Carrot-powered car, coming our way !
will suddenly be in demand on long flights
Yes, lets keep our fictional facts straite.
The reason raw sugar won't work, is because it will kill the ecoli. The water content in the bug is much higher than that in the surrounding media(pure sugar in this case). The water will will move towards the region of the high sugar content (following the gradient of high water concentration to low). This will dessicate the ecoli and kill them.
Now when we say our battery died, we'll mean it literally.
While this development certainly sounds interesting, calling something cheap and stable based soley on a prototype wihout major major long-term testing seems to be jumping the gun a little.
Walk away from the conference table for a few seconds, when you come back there are no doughnuts left! Just a laptop and cell phone sitting there innocently. They'll never tell....
...
. . . for the bacteria.
83% Efficient? Thats impressive, if true. If you think that a typical car engine is only 20% efficient. Maybe one day you could run your car on Glucose..
"You lied to me! There is a Swansea!"
I wonder how safe these bacteria are? Not in any fearful way, but could they
be used to power an artificial heart, getting the sugar from the body? Perhaps
power artificial limbs?

Are you planning to eat these batteries or something? I'd imagine the bacteria would be prevented from spreading by being outside of it's natual habitat, underground.
I've got a scary fact for you. All of the surfaces around you are covered in bacteria. Even that chair, even your bottle of soap, even the water faucets. You cant get away from them. They're everywhere. If you aren't in a full fledged panic yet, you might remember that humans have lived with bactera for as long as their have been humans. The vast majority of them are harmless to humans.
It's also unlikly that a company would release a battery that killed everyone who bought it, and traditional batteries aren't exactly nice to the environment, so the bar is not set very high for these things to be more eco-friendly.
I read the internet for the articles.
As I said, no offence had been intended. I sidestepped diabetes by apparently a very very narrow step last year. My sugar levels were pretty high and I managed to put them down to normal levels through a sugar-free diet and regular aerobic exercise. I also know people who have diabetes and they simply don't care, which is weird enough since the consequences can be grave, if not lethal. One of them reflected what I thought was the point of your post "there will eventually be a cure so why should I diet", something I find stupid, especially since he's fast approaching 200 kilos. It was that attitude I was replying to, not the specific of your situation - you actually have my sympathies as well as my apology for any offence perceived.
Mother is the best bet and don't let Satan draw you too fast.
As biological systems, these battery bacteria should be susceptible to a host of illnesses -- viruses (called bacteriophages), mold, other bacteria, etc.. Swiping a packet of sugar from the restaurant to fuel a laptop might get you some extra surfing time (about half an hour according to my back-of-the-envelope-calcs) or it may get you some nasty battery disease. Will we need public service announcements on practicing safe laptop recharging?
Sugar may be cheap, but sterilized sugar solution in a handy refill cartridge will cost a pretty penny. And, yes, it only means more sweet spam.
Two wrongs don't make a right, but three lefts do.
Yoghurt contains mass produced bacteria.
Most soft cheeses like Camenbert and Brie depend on bacteria for their production.
Bacteria is used in most sewerage treatment plants.
You're hatching them in your gut and every day you shit them. Multiply that by everyone in your city, the world etc and be very afraid. Ie you are mass producing them.
Did you know living in an environment artificially depleted of bacteria (eg too much bleach), can increase your chances of things like Asthma?
Bacteria are used every day by farmers to control other pests like mould and fungus and caterpillers (dipel). (Ironically penicillin is a fungus to control bacteria). Bacteria are also important to good quality soil and natural recycling of vegetation and animal manure.
It probably wouldn't be a good idea to eat your phone battery, but that's no reason to be afraid of it.
Bacteria only multiply out of control in very favourable conditions. That's why they say you should keep your food refrigerated or boiling ie keep your food at temperatures not conducive to growing toxic bacteria like some salmonella.
I suppose you still eat chicken or eggs? The salmonella is not completely eliminated, only minimised...
And bacteria doesn't generally "spread" really fast without help.
