StonyandCher writes "Sony has created a battery that produces electricity by breaking down sugar. The bio cell, which measures 39 millimeters cubed, delivers 50mW — a world record for such a cell, according to the company. 'In the bio cell sugar-digesting enzymes at the anode extract electrons and hydrogen ions from the glucose. The hydrogen ions pass through a membrane separator to the cathode where they absorb oxygen from the air to produce water as a byproduct. The electrons flow around the circuit outside the device producing the electricity needed to power it.'"

Battery Product Name? (Score:5, Funny)
Sony refers to the sugar powered battery as a "Teenager".
Note: Purchasing teenagers is illegal in every country except Saudia Arabia and Nigeria.

Yes, but it's been conclusively determined that you can't get any useful work out of a "Teenager" no matter how much sugar you feet it.
Now if you could harness the power that comes from the laser-like glare of contempt they constantly produce, you could probably power a small town...

Besides that though, the article makes no mention of how much power the battery actually holds, i.e. who cares if it can put out 50mW if it can only do it for two minutes.

Close, but no cigar. A bar that's 3.9cm x 1cm x 1cm is only 3.9cm^3. On the other hand, a bar that's 5cm x 3.9cm x 2cm is 39cm^3, which is still a nice-size battery for a laptop (assuming the article meant 39(mm^3) rather than (39mm)^3), if it can last as long as is expected of laptop batteries.

Food subsidies are *EVIL* (Score:4, Interesting)
I'll just point out that the subsidised food actually drives the poor farmers out of business and reduces the amount of land that is then dedicated to farming within the poorest regions. The really nasty problems start when there's a subsequent drought and the remaining productive land doesn't produce enough food to feed the population. The result is famine, starvation, death and a greater need for aid.
Another problem appears when you have thousands of disaffected unemployed ex farmers just sitting around. Ideal supply of soldiers for anyone who decides they want to rebel against their desperate situation. Which obviously makes everything an order of magnitude worse. It's no coincidence that areas which receive lots of aid are areas which have problems with ongoing conflicts. It's a self reinforcing cycle.
Really, food subsidies are a form of economic warfare which attacks the poorest, most wretched, most defenceless people on the planet...
EU and US farmers are directly the cause of millions of deaths in the 3rd world.

Are these in use yet? (Score:5, Interesting)
I know they're planning to have all sorts of implantable blood-powered sensors that send radio signals out to monitors. So, for one example, a diabetic can have a continuous blood glucose meter implanted in their wrist, which is powered by something like this, and sends wireless signals to a wrist-watch that gives continuous readings of blood glucose, bypassing all the finger-pricking blood tests. And the watch could then store that data and send it to the computer, where they can track it, graph it, correlate it with diet and exercise, recognize trends in the disease, etc. I'm sure there are endless cool potential medical uses. But I've been hearing about this for many years now, and while I'm sure I could Google up how it's going with a few hours of reading, would some knowledgeable Slashdot reader like to just cut to the chase and tell us where things stand?

And where do hydrogen cells get the hydrogen? (Score:5, Informative)
Supposing that the biogenesis theory of fossil fuel production is correct (the classic theory, that says it comes from living things over long periods and as such is not renewable) we are going to run out of it at some point. Unless you think we should all go live in the wilderness without power (in which case I say you first) we need to find alternate energy sources. Biofuels may well be a good one.
Hydrogen isn't a solution by itself. We may start using it as a more efficient way to store and transport power, but to get it we need to get energy from somewhere.
Unless we are going to take the Luddite answer of saying we need to stop using technology that requires power (which will lead to millions, perhaps billions of deaths as we cannot sustain the current population on preindustrial means) then we have to look for alternate power sources. We can't stick our heads in the sand and just whine about problems. Any energy source will come with problems, that's just life. The problems have to be weighed against the benefits.
Also please remember: Biofuels are in their infancy. Maybe we should keep investing and working, see if we can't figure out ways to make it more efficient. Plants are pretty efficient little solar cells, when you get down to it, we just need to work on getting ones that we can then efficiently turn in to other forms of energy.

They need to concentrate on getting power out of byproducts like veggie diesel. Now gimme a walkman with a small diesel engine running a small generator and then I'll be happy. Granted i'll have to stand in one place because it'll be too heavy to carry. And my hands will stink after fueling. At least grease doesn't explode to readily.
Hey, here's a question. Would a Vegan drive a volkswagon that runs off of animal fat grease? What a delimma... it's already dead, and it would be 'green.' What about a car that runs off of roadkill. Ok, this is going to be modd'd offtopic
